My prints have Lines across Them

Have you ever seen lines across your printouts? These are known as light stripes, a common print quality issue with ink and toner cartridges alike. Luckily, there is a way to easily fix this issue with inkjet printers, as well as laser toner printers.

With an inkjet printer, the first step is to identify which colors are producing the stripes. Looking at our image of the parrot, we see consistent black striping going horizontally across the printed image. At first it looks as though the black may be coming out when it is not supposed to, but the actual problem occurring here is with the black ink cartridge not ejecting enough ink throughout the page. When we zone in on the lower beak of the parrot, white lines are clearly visible where the black ink is supposed to be.

Similarly, the picture of the boy with painted hands shows the magenta ink cartridge not producing ink consistently, resulting in the same light stripe pattern occurring where the magenta ink is supposed to be. This often occurs with new ink cartridges, cartridges that have been sitting for a while, or when printing images that use both light and dark versions of the same color on one printout.

After identifying the color or colors giving you the issue, the next step is to remove the cartridge and clean the contact spots (usually the bottom of the cartridge where ink is dispelled) on the ink cartridge and the printer with a damp paper towel or something similar. This will help remove any debris or dust that can build up and clog the cartridges.

The final step is to print a Test page of the color(s) in question. This will help clear the nozzles / printheads of any dried ink or residue and will also help stir the ink mixture inside the cartridge as the cartridges move inside your machine. You may have to run the test multiple times to completely clear the nozzles.

The test pages should be producing more solid coloration on each consecutive printout. If a test page prints out with the same amount of striping, or the striping has not faded at all from the previous test print, we recommend taking the cartridge out and cleaning the contacts once again with a damp cloth.

Once the test page is printing solid colors without the striping effect, the cartridge is ready to be used once again on your printouts. Cleaning the ink cartridges with a damp cloth and printing test pages can be done as many times as necessary, and will not damage the cartridge, ink mixture, or printer.

List of Steps to Remove Ink cartridge Light Stripes:

1. Identify the color(s) causing the striping to occur.

2. Remove the problem cartridge(s).

3. Clean the contact spots of the cartridge and printer with a damp cloth.

4. Print test pages of the problem color(s) to clear nozzles.

5. Repeat steps 2 – 4 as many times as necessary.

 

Laser toner printers and cartridges can also produce a striping effect across your printouts. And unlike inkjet printers which are not distributing enough ink, striping occurs on laser toner printouts because of an excess of toner powder on the drum unit. This usually occurs after a paper jam or when printing out a new document after having just printed a large number of copies.

The quickest way to eliminate stripes with a laser toner printer is to open the machine and gently wipe the surface of the drum unit with a damp paper towel or something similar. Once the area of the drum unit showing has been wiped clean, carefully rotate the drum unit manually so a new portion is showing. Simply rotate and clean the drum unit with the damp cloth until the entire surface of the drum unit is clear of all toner powder and debris.

Once the drum unit has been cleaned, your printouts will no longer contain blotchy spots or stripes. If the problem persists and becomes a constant issue whenever starting a new printing task, it is time to replace your maintenance kit. The purpose of the maintenance kit is to clean to drum unit between prints and to collect any excess toner powder that was dispersed and not used. A consistently dirty drum unit is an indication that the maintenance kit needs to be replaced.

List of Steps to Remove Stripes and Blotchy Spots with a Laser Toner Cartridge:

1. Open the machine to expose the drum unit.

2. Gently wipe and rotate the drum unit with a damp cloth.

3. Close the machine and print.

How Inkjet Printers Work: A Look at the Components

Inkjet printers are all around us and used every day to create a vast array of projects from important documentation to photographs taken just prior. An inkjet printer works by creating extremely small droplets of ink and jetting them onto a substrate or surface passing through the printer. The jet of ink droplets is guided by a series of nozzles contained in printheads and release to create a specific pattern based off layouts given to the printer from a computer or other digital device. Small electrical impulses will trigger the ink cartridges to release or eject ink at the appropriate times, forming dots onto the media and eventually creating images and texts. The inkjet printer will be able to handle simple layouts such as text documents and extremely complex layouts that have details challenging resolution capabilities. Inkjet printers are the most common type of household printer because they generally have a quiet operation and can produce photograph quality results.

What components are needed and how do they work?

Inkjet printers have a lot of internal components that affect the overall quality, speed, reliability, and durability of the printer and its ink cartridges. To better understand how the printer works, an understanding of what components are needed, what their functions are, and how they interact with each other is needed.

The Ink Cartridge

Ink cartridges or inkjet cartridges are the starting point and most recognized component in an inkjet printer, as they are the only component that must be replaced when the ink runs out. There are several different types of ink cartridges and they vary greatly depending on the printer model and manufacturer intended for. Ink cartridges can contain black ink only, black and color ink in a single cartridge, just color inks in a single cartridge, or separate cartridges for each individual color. Many photograph printers will even have light cyan and light magenta cartridges to provide life-like tonality on photograph printouts. The main purpose of the ink cartridge is to house the colorant or ink, until being released into the printheads.

Printheads

The Ink cartridges are directly connected with printheads or contain their own printheads built-into the cartridge. The Printhead is where all the magic happens inside the machine and is the component responsible for guiding the ink onto the page. A printhead consists of a series of tiny nozzles that are used to jet out or spray the aqueous ink solution from the cartridges to the piece of media passing through the printer.

When separate from the ink cartridges, printheads are the component that you snap the ink cartridges into when replacing ink. They look a lot like a trough or sunken in bench with small round protrusions arising into the ink cartridges. The round protrusions will insert into the cartridges when snapping them into place opening a passageway for the ink to travel down during the printing process.

An ink cartridge that contains its own printhead will rest at the bottom of the cartridge and looks like a computer chip or smoothed metal contact filled with tiny circuits and groves. Both printheads, separate and included, are responsible for letting the cartridge know when and where to release the ink.

Control Circuitry

In order to figure out the precise mathematics of when to release ink and when to hold back ink, a Control Circuit is interposed between the printer driver from the host computer and the printer itself. The circuit will actually control where energy is distributed amongst the chip and where to remove current flow. This will cause the ink cartridge to open or close particular nozzles to either start jetting ink out or to stop the flow of ink.

The printer driver on the host computer will translate images and text documents into a mathematical map or grid known as bitmap. The process of translating the images from a computer to a grid is known as the Raster Image Process. This lets the printhead Control Circuit know when to energize a specific spot on the circuit, releasing the ink and when to de-energize an area to stop the flow.

Stepper Motors

A Stepper Motor will rapidly move the printheads and the ink cartridges back and forth inside the machine and across the width of the media passing over every portion of the paper.  The Stepper Motor also has a secondary job of putting the rollers in motion during the printing process. This is achieved in a number of ways from belts to meshing gears, a common way to get multiple parts moving. The purpose of the Stepper Motor is to transform received electrical power into motion, which is basically making the internal components move.

Stabilizer Bar

Included with the printheads is a Stabilizing Bar that evenly distributes force on the printheads when they are in motion, moving quickly back and forth along the media. As the printheads and ink cartridges rapidly move back and forth, the inner particles are pulled from one side to the other. Similar to being in a car that is taking a sharp turn, the centripetal force will push you to one side of the vehicle. The Stabilizing bar helps to keep the cartridges at a steady angle to eliminate or reduce this effect. This will help keep the ink formulations from clotting or collecting in one location of the cartridge.

Belt

A belt is also one of the components found inside an inkjet printer. Just like the belts used in car motors, the printer belt is used to rotate additional parts. A belt is generally banded to a rotating component on a motor and stretched to wrap around other components that need to rotate. When the motor is powered on, a magnet will rapidly start rotating inside the motor causing external components on the motor to also spin or rotate. The belt uses the spinning force of the motor to spin or rotate the other parts that need to move.

In the inkjet printer, the belt is connected to the printhead assembly from the stepper motor, in order to move the ink cartridges back and forth inside the machine. Belts can also be used to assist the rollers found inside printers.

Rollers

The purpose of the rollers is very simple. They are used to carry or drive a piece of media (usually paper) through the printer. The rollers will grab a piece of media from the top of the stack placed inside the designated Input Tray and will transport that piece of media underneath the printheads and ink cartridges before ejecting the finished printout to the Output Tray. Some office inkjet printers that have Automatic Duplex capabilities can even have rollers that drive the media back through the printer to expose the reverse substrate underneath the printheads to create two-sided printouts.

Paper Trays

Another very recognizable component of the printer is the Paper Trays. Typically Inkjet printers will have a single Input Tray located at the top or back of the printer and a single Output Tray located in the front of the machine. Another common tray configuration is to have the Input Tray and Output Tray conflated into a single front-feeding tray. When both are used as one tray, such as with the HP PSC series printers, the tray will usually have small mounting members on either side of the tray to elevate the printed material from entering back through the printer. These also act as guides when loading new media into the Tray and as a divider between the Input and Output sections of the tray.

Power Supply

To supply power to the stepper motor and control circuitry a standard power supply has been incorporated into the printer. The purpose of the power supply is to convert the alternating current (AC) from a wall outlet to more controllable direct current (DC), needed to operate the stepper motors and circuitry inside printers. The power supply is also responsible for lighting up and energizing additional features such as display screens and scanning equipment.

Interface Ports

Also included with inkjet printers are ports that allow users to connect and transfer digital data between devices. The most common printer interface is the Hi-Speed USB 2.0 port which was created to outperform the older IEE Parallel interfaces. The Hi-speed USB 2.0 ports also broaden the range of external peripherals or devices that can be connected with the printer. The Interface ports main purpose is to provide a means to transfer data (usually text documents and images) from the computer to the printer and vice versa.

Photograph inkjet printers will typically have compatible media card slots as well, that allow users to walk-up and plug media cards and flash drives directly into the printer to print the files and photographs on the card without needing a computer.

These are the main components that can affect the output quality, durability, and performance of an inkjet printer and its ink cartridges. Hopefully this will help you identify and possibly prevent or fix any issues that are occurring with your machine.

What is a Toner Cartridge?

Toner is a reasonably familiar substance to most people working in offices or for companies that have office photocopy machines and big industrial printers. These machines inevitably use toner to form images and text onto a sheet of media, usually being a plain white piece of paper. In other words the toner acts with the same purpose ink has, although ink is an aqueous solution whereas toner is in the form of powdery, dust-like solids. And due to the fact toner is a powder, cartridges should not be shaken as the material can spread through the air and adhere to unwanted surfaces, permanently dying them. Before handling any toner cartridge, make sure you are aware of the potential dangers and health risks involved with these units by clicking here.

In its early form, toner was a mix of carbon powder, iron oxide, and sugar. Eventually, to improve the quality of the printout, the carbon was melt-mixed with a polymer. The polymer is a thermoplastic that now comprises about 40 to 95 percent of the toner mixture and is crucial to binding and carrying colorant to the drum unit and substrate. The polymer is often referred to as the “binder” being able to hold the toner powder mixture together, carrying the powder to the transfer belt or drum unit, and holding the mixture in place for the heated fuser rollers to bind the powder to the paper with heat and pressure.

To better understand this process, let’s take a look at the different components that make up a toner cartridge and their functions. A basic toner cartridge contains several parts; one common component in each cartridge is the hopper which houses the toner powder until being picked up by a magnetic developer roller. The magnetic developer roller is a cylindrical sleeve used to transfer image forming toner powder particles to an image forming drum unit. This roller protrudes partially into the hopper and has several magnetic beads inside that will attract the toner powder mixture from the hopper to the roller during the printing process. As this piece rolls, the picked up toner is brushed against the drum unit.

The drum unit, having a greater static attraction, will once again pull the toner powder but this time from the magnetic developer roller. Any excess powder on the developer roller will be scrapped off with an MDR Doctor Blade before passing by the drum unit. The MDR Doctor Blade is a precision leveling blade that is designed to keep only one layer of toner powder on the developer roller. This ensures more evenly distributed toner and helps to prevent the drum and toner cartridge from clogging. The magnetic developer roller also has a secondary blade, known as the MDR Sealing Blade, to clean off any powder left on the surface of the roller after passing by the drum and before rotating back into the hopper section.

The drum unit itself is sometimes included with the toner cartridge in 2 in 1 or all inclusive toner cartridges. And whether the drum unit is a separate unit or has been included with the toner cartridge, the drum serves the same purpose. The drum is a photoconductive cylinder that contains a laser neutralized image of the project about to be printed out. A laser will actually neutralize parts of the drum unit, based off the desired image about to be printed. The neutralized parts of the drum will not be able to attract toner, which is how the drum forms an image, only being able to attract toner where desired on the image. Once the drum unit has picked up the toner powder from the developer rollers, the unit will then transfer them immediately to the paper substrate passing through the machine.

To keep the drum unit charged, a primary charge roller inside the toner cartridge rests against the unit, recharging the drum and eliminating neutralized areas of the unit. The drum also has a cleaning blade know as the Organic Photoconductor Wiper Blade. Any extra toner left on the surface of the drum unit after transferring the powder to the paper will be scrapped of by the wiper blade into the waste container. The last part to creating a printout involves the fuser rollers and some assisting transfer rollers that drive the media through the machine and are usually separately sold components that do not need to be exchanged as frequently as toner cartridges or even drum units.

All these components are necessary pieces to having a functional toner cartridge that can produce images onto a piece of paper using pigmented polymers, colorants, and carbons as the ink or image forming material being adhered to media. The current laser toner cartridge powders are comprised of a mixture of colorant pigments, external additives, and wax substances in addition to the binding polymers. The external additives can be iron oxide molecules, chemical release agents, charge control agents, and flow agents all designed to keep the mixture at optimal functioning compositions. Many toners now have protective wax coatings encapsulating each toner powder particle for longer lasting printouts and resistances to smudging and blurring.

Smart Chips on Printer Cartridges

Many printer manufacturers’ have added a smart chip to some of their ink and laser toner cartridges in an attempt at combating the fiscally beneficial Refill Kit and Compatible or Remanufactured ink and toner cartridge market. The sole purpose of the smart chip is to count the number of droplets dispensed from the device and report that data to the printer to track ink usage until a predetermined amount has been reached. Once that amount has been reached, the printer will display one of several messages, such as “low ink,” “out of ink,” “replace ink,” and other similar messages that prevent the user from continuing to print. These messages can also appear from time to time if a third party cartridge is used that is not recognized by the printer, even though it was just installed and is full of ink or toner. Simply refilling the cartridge will not fix the error message either, as the chip measures dispensed droplets and not the actual amount of substance inside the tanks. To solve the error message issues, there are a few different solutions consumers can try.

Solution 1: has hidden costs and can be messy

One route is by purchasing a refill kit and chip re-setter device, which is a small box-like device with a few metal prongs (or contacts) protruding out in one little section. These are very easy to use and only take a few seconds to operate. To reset the chip, the user simply has to align the chip on the cartridge to the prongs on the re-setter device and hold it there for a certain number of seconds. The re-setter will then “reset” the chip, allowing users to print the predetermined amount once more. There are some dangers involved in refilling your own cartridges and this method is not recommended unless you have a very safe and clean environment to work in. This method is messy and some toners can be toxic when inhaled or rubbed into the skin. Moreover, the device itself is an additional cost that cuts into the savings earned when refilling the ink and toners yourself.

Solution 2: free but can be complicated

There are some software companies out there offering free programs that can help the user take control of the printer’s chip such as the SSC Smart Chip and Printer Service Utility for Epson Printers. The program works with most Epson Desktop printers and was designed to reset the chip or “freeze” the count in cases where resetting is not possible. “Freezing” is a method that suspends the chip from transferring the droplet count data to the printer, which prevents the printer from locking your cartridge when reaching the predetermined amount of droplets. Freezing the chip can only be done with brand new cartridges before the user starts to print but allows the users to refill and reuse the same cartridges. These programs should always be free to use, so do not get fooled into purchasing a plan from another company offering someone else’s free software.

Solution 3: easy and affordable

The recommended option is to simply purchase Remanufactured or Compatible cartridges from a quality third party ink and toner distributor. Compatible cartridges and Remanufactured cartridges are always offered at reduced prices from the OEM (Original Equipment Manufacturer) or brand name cartridges, helping users save anywhere from 30 to 82 percent off retail. And when purchasing from quality distributors such as Inkgrabber, you can feel safe knowing that all their products have been tested and ISO9001 certified to ensure pristine functionality. These companies produce their own compatible products or refill OEM cartridges and place brand new smart chips on them for a 100% guarantee of compatibility and performance.

Refilling Ink

Is refilling ink cartridges the right choice for you? Refilling cartridges has its advantages and disadvantages depending on where and how it is done. There are several options to consider before making the decision to refill cartridges. The point is, of course, to obtain the best deal, without having to spend so much time on the project as to negate the savings through your own manual labor. That is the tricky part, but knowing what type of kit to buy and how to fill your cartridges can make all the difference.

There are two main types of ink compositions from long-lasting pigmented inks like ChromaLife 100+, DURABrite Ultra pigments, Vivera Inks, and UltraChrome inks, to bolder dye-based concoctions found in most inkjet printers today. The pigmented inks are made up to tiny encapsulated particles that sit on top of a substrate instead of absorbing or sinking into the page like dye-based inks. This helps with placement and overall resistance for printouts that have finer line detail and last longer without fading. However, due to the rather complex chemical formulation, pigment based inks are not refillable (for the time being). So inevitably, ink refill kits are going to be dye-based mixtures in three colors and one shade.

Luckily most refill kits are sold specifically for certain printer models or by the number found on the original cartridge. The color refill kits contain a cyan (blue), magenta (red / pink), and yellow ink bottle each with an accompanying syringe or plunger to transport the liquid from the bottle to the cartridge. The black ink refill kits also contain a bottle or two with accompanying syringes and / or plungers to help streamline the process. When filling a cartridge at home or by yourself, make sure to watch instructional videos or thoroughly read the instructions provided with the purchased refill kit.

Each kit has some similar steps such as working over paper towels and placing or peeling back a guide sticker to direct the insertion of the syringe or plunger, but they all vary slightly. The instructions will provide helpful tips to prevent the cartridges from overflowing or being pierced in an incorrect spot which can lead to leaking. Once a cartridge has been filled, the instructions will most likely suggest letting the cartridge sit for a moment, before doing a final wipe clean and inserting the piece into your machine, to allow any excess ink to drip out.

Taking a cartridge to major store chains such as Costco, Walgreens, and Office Max to be refilled may seem like an easy alternative to refilling the cartridge yourself but beware. The employees have no formal training in office supplies or how ink cartridges work. They are simply minimum wage workers with no prior experience refilling ink or toner. And frequently, customers end up with messy components that leak after taking them to be refilled at the chain corporations.

Before ordering a refill kit, be sure to check out the directions or steps associated with the particular kit. This will help you get an approximate understanding of how much time the entire process will take. If the steps are only going to save you a couple dollars but take an hour to complete, the refill kit may not be the way to go. However, if you have a chance to save tens of dollars and the steps do not seem cumbersome or time consuming, the Refill Kit can be the most advantageous. The Refill Kits provide enough liquid to fill the cartridges multiple times (around 4 to 8 times each) which can significantly reduce the cost to operate your printing machine.

The Final, and perhaps easiest way to obtain a refilled cartridge is to simply buy a Remanufactured ink cartridge. Remanufactured Ink Cartridges are simply refilled cartridges that have been returned or recycled to the vendor. The difference between filling an ink cartridge yourself and having the factory do it, is the testing steps. At the factory, all the cartridges have been cleaned and inspected before and after being refilled to ensure defective products do not get shipped out. They also have the volume to simply throw out or disregard any cartridges that can lead to potential issues.

Is too much Toner Ink Exposure Dangerous?

Most users of laser toner printers and photocopiers are unaware of the dangers mishandling toner can have to their health. The toner powder used inside each cartridge contains compounds that can be potentially harmful to humans when not handled correctly. The key to properly handling toner is being aware of the risks and how to prevent them from occurring.

The International Agency for Research on Cancer has classified toner powder as a type 2B carcinogen with the primary ingredient in most laser toner cartridges being Carbon Black. Carbon dust, which toner is mainly composed of, is known to emit carcinogens which can be dangerous to humans and result in a form a cancer when inhaled. Normal operation of photocopiers and laser printers will not expose users to these possible risks; however a broken cartridge that explodes toner powder in the office can be a different story.

To avoid overexposure to toner by inhaling or touching the chemical, gloves and a paper breathing mask should be worn to clean the mess. If any of the toner compounds get onto your skin, you should wash the toner off under cold water. Hot water or even warm water can melt the powder into your skin which can ultimately attack or transform bacteria resulting in some undesirable side effects such as irritation and itchiness. Inhaling the carbon-dominate dust may cause headaches, eye irritation, chronic itchiness, and even small growths on the tongue.

When laser toner cartridges inside of some photocopy machines overheat, the toner can conceivably become even more dangerous. First of all, the cartridge itself can severely burn the skin when handling the toner ink cartridge immediately after printing.  So do not attempt to replace toner cartridges that have recently been used to print with. Give the cartridges a few minutes to cool off inside the machine before changing the toner.

Secondly, photocopiers that use toner ink may emit carbon monoxide into the atmosphere when overheated. Inhaling a cloud Carbon Monoxide can cause an increased heart rate, severe headaches, and drowsiness. To prevent exposure to overheated toner cartridges emitting carbon dioxide, these machines should be used in well ventilated rooms. Opening windows and doors can also be useful to help dilute the air containing the carbon dioxide pollutants.  The most common occurrence of this happening is in offices that are consistently printing throughout the day. So be sure your frequently used laser printers and copies are in a well ventilated room before operating them.

Furthermore, some photocopiers are likely to radiate high levels of ozone during electrical discharges that occur each time toner is ejected from the cartridge. And regular exposure to high levels of ozone can cause some unwanted effects, similar to the effects of overexposure to carbon dioxide, including headaches, irritation, nausea, and even dermatitis in extreme cases. By ensuring your machine is operating in a well ventilated area will prevent this from becoming a potential problem.

Once again, the normal operation will not have harmful effects to users. And to eliminate the potential threats mentioned, be sure to use laser toner printers and photocopiers in areas with good air flow or ventilation, wash toner off with cold water, do not breathe unnaturally close to the machine when operating, and do not attempt to replace or change recently used cartridges. By following these fairly simple guidelines, laser toner printers and photocopiers using toner ink are relatively harmless and are necessary office components in today’s workplace.

Ink or Toner?

Ink and toner share many similar aspects, both being able to administer color and black pigment onto media forming specified characters and integrated images that make up a printout. Each is comprised of three main elements, a vehicle, a pigment, and a holding cell. Both laser printers and inkjet printers also come in a variety types from All-In-One devices, being able to print, scan, copy, and fax, to monochrome machines that were designed to handle black and white or grayscale only printouts. These machines can be used for the same purposes, having the ability to complete nearly any type of printout, although toner and ink have distinct advantages and disadvantages depending on the type of printing you are performing. To help better understand which type of printer will be more beneficial, we have to first understand to main properties of ink and toner.

Printing ink is a liquid or paste based solution used to create shapes and patterns onto the substrate. The liquid solution is housed in a reservoir within the cartridge until being forced to the release chamber(s). Once inside the release chambers an impulse will trigger a reactive element embedded to the chamber to forcibly jet out or drop the pigment through a nozzle and out onto the media. The reaction will also force new droplets into the chamber for rapid reproduction.

Toner is a type of concentrated pigment or dye-based powder used in laser printers to complete the electrophotographic process. The powder is stored within the cartridge compartment known as the hopper. The powder in the hopper is a carbon-based polymer that will attract and repel from particular static electrical charges which is the key to applying the powder to the substrate. A transfer roller will pick up the oppositely charged toner particles from the hopper and roll the particles against an imaging drum unit that has an even greater opposite electrical charge. The laser printer will create a light impression on the drum successfully creating a magnetic impression for the toner to attract to. Once the toner is placed onto the media, a pair of fusing rollers will actually melt the powder into the page to create the desired images.

There are three main properties to consider when choosing whether to print with toner or ink, including how they dry, the structural design, and the optical output. With a laser toner printer, the fusing rollers will burn the toner that has been layered on the substrate to adhere the particles to the page. Inkjets will apply an ink solution that rapidly dries being exposed to the room temperature air. The speed at which the ink will dry varies, depending on the added drying or thermal agent inside the ink mixture.

The cartridges are also made in completely different sizes and shapes, with toners generally being much bigger in size due to the amount of components (or pieces) needed to apply the pigmented polymers. And having an entire roller covered in particles that spans the size of the accepted media and a drum unit that holds an image, allows the laser toner to swiftly reproduce that same image, which is ideal for printing out multiple copies of one page. Inkjet printers will slowly render and apply ink as the cartridges pass over the media to help capture fine details, making them better for single page printing.

Toners are made and formed with very specific particle solutions and processes that pertain to the particular printer model. For example, some toner particles can be shaped by a vortex procedure giving each grain a rounded shape, whereas the more typical chemically created particles contain jagged edges and can damage rollers that are made to transport rounded particles. Therefore, most toner cartridges will only work with a specific printer or series of printers. The inkjet cartridges, on the other hand, are often interchangeable with several printer series and even manufacturers. When the ink formulations are changed, the viscosity is usually balanced between inkjets allowing almost any printer to apply the contained ink as long as the cartridges have the same size and shape.

In general Inkjets will be able to produce higher quality images and photographs, whereas the toner particles are able to create higher quality text documents. The laser toners will also be able to produce more printouts due to the sheer amount of pigment able to be held by the toner cartridges as opposed to the ink cartridges. Ink cartridges are typically more expensive when comparing the cost to print per page although they can provide a wider color gamut to work with and added definition. So depending on what types of printing you are performing more of, will determine the type of printer and cartridges that will be more beneficial. For the photograph enthusiast, inkjets are recommended for added detail. To create multiple copies of a single page or text documents, a laser toner printer and toner cartridges will be better for your overall printing needs.

What is a Drum Unit?

The Drum Unit is an integral part of technology used in laser printing and photocopying to create an image and transfer that image onto paper with the use of toner and heated fusing rollers.  First the photoreceptive cylinder, known as the drum unit is negatively or positively charged.  Then a laser will transfer the desired image to the surface of the drum by neutralizing the areas on the surface where the image would be.  The toner, after being charged negatively or positively is exposed to the drum unit.  The toner will attract to the areas of the drum in which the laser has passed over and neutralized, while the remaining toner will be repelled from the areas of the drum untouched by the laser, having the same electrostatic charge. The drum then rolls over the paper, transferring the toner to the paper.  Once the toner is on the paper, it will pass through heated fusing rollers to melt the toner onto the page, leaving the desired image behind. Inkgrabber.com offers all three varieties of Drum Units including the Original Equipment Manufacturer (OEM) or Genuine drum units which are created by the printer manufacturer, the Remanufactured drum units which are refilled genuine drum cartridges that are tested to ensure quality performance, and the Compatible drum units which are created as a generic alternative to the OEM and can be offered at a fraction of the genuine cartridge price.

All products, including the Brother DR-350, are ISO 9001 certified, meeting the highest standards. Every Remanufactured, Compatible, and Genuine Brother Drum Unit has up to a 2-3 Year Shelf life and is backed with the Inkgrabber 90 Day Money Back Guarantee. In addition Inkgrabber.com also provides a 1 year cartridge exchange policy for damaged or faulty hardware.

How does a Copy Machine work?

Copy Machines and / or photocopiers have a dynamic ink delivery system utilizing static electricity to pull pigmented polymer composites (toner powder particles) to a specific image transferred onto the surface of the drum. The image being transferred is taken from the original paper being copied.  Then heated fuser rolls melt the toner particles on the drum, adhering the toner to the page being created. Inkgrabber.com uses only the finest quality pigmented polymer composites in all Copier Toner cartridges available. Inkgrabber.com offers all three varieties of toner cartridges including the Original Equipment Manufacturer (OEM) or Genuine cartridges which are created by the printer manufacturer, the Remanufactured cartridges which are refilled genuine cartridges that are tested to ensure premium performance, and the Compatible cartridges which are created as a discounted alternative the genuine cartridge.  All products, including the Canon e40, are ISO 9001 certified, meeting the highest standards and offered at only $[+RETAIL_PRICE+].

A Belt Unit or Transfer Belt serves the function of collecting toner powder particles from each photoreceptive drum unit. Each drum unit will contain an electrostatic image pertaining only to the color of the toner being applied. Most color laser printers will contain four different drums for each color (cyan, magenta, yellow and black).  Other laser printers will vary depending on the amount of individual toner cartridges inside the machine. As the belt passes over each drum, the original image will develop on the belt, layer by layer, color by color. Once the belt has passed and collected toner from each drum unit, the belt will carry the toner to one last transfer roller. The last transfer roller will emit a high-voltage, static pulse attracting the toner from the transfer belt toward the roller, to be intercepted by a passing piece of paper. Any leftover toner particles on the belt will be cleaned (or scrapped) off by a small rubber blade before starting the process all over again.
