What is common to both toner cartridges and solar panels? Both require energy to carry out its respective operations and work efficiently. Solar panels need sunshine to store electrical energy into its storage batteries while cartridge units run on electrical energy to sustain the supply of DC voltage bias to its magnetic rollers. In the absence of solar energy, the solar panels will not be able to convey electrical energy into its batteries resulting to insufficient power supply in line with the underutilized energy storage bins. Meanwhile, the toner cartridge will not be able to supply adequate toner powder to form the raster graphic image and bond its particles on the media, to cause uneven toner delivery and consequent defects over printouts.

Toner powder per se is non-toxic. Therefore, the material is deemed non-hazardous to laser printer users who come in closer contact with it. However in the process of laser printing, as the fuser melts toner at 200 degrees Celsius, fumes and gases are emitted. Experts claim that the inhalation of these gases can cause minor inconvenience to the person operating the laser printer. Therefore it is in the best interest of all users for laser printers to be located in an area where gases and fumes can be contained.

The imaging system of a laser printer is a toss-up between the OPC photoreceptor drum and the laser scanning assembly. After the image is formed on the OPC drum, toner powder is introduced simultaneously. Through the action of static electricity, toner literally jumps into the paper media and the whole (paper and toner) thing moves into the fuser to permanently bind toner to paper. The laser printer component responsible for supplying a sufficient amount of toner to the photoreceptor drum is the detachable toner cartridge.

5 Recycling Tips for the Brother TN-350 Toner Cartridge

Are you intending to refill the toner supply of your Brother TN-350 toner cartridge? Why not use the Brother TN-350 toner refill kit to just that. The refill product comes supplied with high grade toner powder that is designed to deliver the same quality prints and yield as the OEM toner. Refilling the toner cartridge is so easy that you can actually complete replenishment in less than 5 minutes. As an added reference, find below a few tips relevant to the replenishment and Maintenance of the TN-350 toner cartridge.

Vacuum Dry the toner cartridge’s supply chamber. As much as 70 grams of toner routinely lingers in the supply chamber of the toner cartridge, even when the printer has already alerted you with the “Toner Out” prompt. Thus, before proceeding with the refill, make sure that the toner hopper or supply chamber is sucked free off toner residues. Failure to do so will cause backgrounding and may even damage the toner cartridge.

Clean the Developer Roller and Blade. Using the lint free cloth, wipe off bits of toner powder that may be sticking to the developer roller and blade. Again, this will keep the cartridge from backgrounding while extending its serviceable life.

Replace worn out components. If it’s the second or third time that the cartridge is being replenished of toner, better inspect the condition of pertinent parts. Replaceable components such as the drum, transfer roller, doctor blade and developer roller will wear out over time and will require replacement to ensure the cartridge’s sustained functioning.

Clean the printer before and after replacing the cartridge. Apart from tidying the laser printer’s casing as well as removing spilled toner powder, dust and paper fragments; it is also recommendable to perform automatic cleaning and test prints using the printer’s bundled software.

Do not recycle toner powder. Used toner will not only cause backgrounding but also contaminate the cleaning mechanism of the drum unit. Eventually, bad toner will contaminate the newly installed toner and shorten the cartridge’s useful life.

Do not use chemicals to clean cartridge components. Avoid using ammonia based cleaners to prevent causing permanent damage to the toner cartridge. Instead, use a dry, lint free cloth to clean cartridge internal components.

Do not touch the transfer roller and fusing area. Avoid hand contact with the transfer roller and fusing area. Doing so would leave skin oils on the surface which could trigger print quality problems and affect the fusing of toner powder to paper respectively.

Observe proper gear maintenance. The gear side of the toner cartridge also requires careful maintenance to guarantee the proper functioning of the unit. The gear shafts should be adequately greased and replaced with lithium grease if shaft is dried up. In case toner powder contaminates the grease, the shaft and gear should be wiped clean of toner to avoid backgrounding and cartridge damage.

Take note of the above mentioned tips and follow closely the instructional material supplied with the kit; and surely you’ll have that toner cartridge going again in a few minutes. But just in case you encounter troubles along the way while refilling the cartridge with the Brother toner refill kit, rest assured that you have available over-the-phone customer assistance for your inquiries and other concerns.

Why compatible toner can produce OEM-quality prints?

Do you really know what materials are used in the manufacture of those miniscule; electrically-charged powder that adheres and forms images on paper? Moreover, what particular specifications constitute compatible toner powder that allows it to produce decent prints and achieve a yield rating similar to that of the OEM toner?

Chances are that most consumers really do not care so long as the toner product can deliver the print quality and yield it is bruited about. But here is a quick look at toner composition in general and the specifications pertinent to its production.

Toner Powder Composition

Special polymers with low melting points make up the composition of toner powder where each micron-sized grain has been jet milled to a certain particle size in order to match the resolution specifications of the laser printer. These factors combined produce different toner formulations from one manufacturer to another and likewise from one printer model to the next.

Compatible Toner Specifications

Toner grain size. Grain size is set based on the laser printer's dpi (dots per inch) setting which determines potential resolution or the ability of the laser beam to carve the dot size on the photoreceptor drum's surface.Compatible toner supplied with toner refill kits is produced to duplicate the varying grain requirement set per laser printer model. Duplication is important, as an unmatched grain size will result in poor print resolution.

Toner melting point. Toner powder is characterized with low melting points but the melted particles cool rapidly to create a strong, permanent bond with the paper। Heat requirement is dependent on grain size, composition and is likewise designed to match the operating capacity of the fuser; since laser printers require differing temperatures to facilitate bonding of toner particles to paper fibers.

Extreme temperature on the other hand will cause paper burns and prevent toner from being melted properly and consequently adhering to paper. Thus, third party manufacturers likewise observe OEM toner melting point in the design and production of compatible toner.

Toner gram weight. Toner gram weight determines cartridge yield or rating. As such, OEM toner and compatible toner of similar composition and grain size but with differing gram weight will produce varying yield. Toner with less gram weight will definitely generate lesser printed pages.

OEM quality prints and yield is produced when compatible toner supplied with toner refill kits (1) comes in a grain size that matches printer requirements (2) is set with heat temperature that is enough to melt toner and (3) has a similar gram weight as the OEM toner.

Universal Laser Printer Toner - Is there such a thing?

A user of a popular community website asked if toner powder compatible with the Samsung ML1640 can be used on an ML2010 printer series. I take it that the user was considering the refill of an ML2010D3 cartridge with third party toner intended for the MLT-D108S which loads the ML1640 series.

Well, this is typical since same brand OEM toner cartridges are designed compatible for use on other laser printer units from the same or another series, as specified by the manufacturer. The ML2010D3 loads not only the ML2010 unit but also the ML2510 and ML2570 printers. Third party toner on the other hand extends this compatibility across laser printer brands as Samsung ML-2010 toner refill kits can also be used to replenish the toner supply of Xerox Phaser and Workcenter models as well as Dell 1100 toner cartridges.

So can one indeed refill toner cartridges with compatible toners sparingly? In the case of the ML1640 and ML2010, OEM specs do not indicate compatibility and the same goes for third party toner refills. While both units are monochrome laser printers and can produce effective resolution of 1200x600 dpi, yield rating for both the ML2010D3 and MLT-D108S varies at 3000 and 1500 pages - at 5% page coverage.

Page yield is directly influenced by toner particle size and this likely is an indicator of incompatibility, among other factors. In a WhatTheyThink.com interview, Xerox VP Hadi Mahabadi discussed how a 5 micron toner can produce double the yield of a 9 micron toner.

There is no such thing as a universal laser printer toner. While toner composition can be identical, differences in particle size and toner technology used in its production generate various toner formulations that are specific to the output requirements of a laser printer in terms of resolution, speed and yield - including the fusing process. This should then prompt laser printer users to stick with specific OEM cartridges or be meticulous in the choice of compatible toner as well as with vendors supplying toner refill kits because toner is exclusive for a certain laser printer or a particular series and is not compatible with just about any printer unit or cartridge for that matter.

Toner Powder deciphered. Laser printer OEMs base toner specifications on the technical designs of a laser printer, as follows: Toner substances utilized are usually of the styrene acrylate copolymer, polyester resin, styrene butadiene copolymer and a few other polymers, tested by manufacturers to fit a printer’s specification. Toner formulation differs for each laser printer model, particularly on the percentages of substances deemed necessary to produce the desired printed output. Granule size is also a major consideration since it will all depend on the laser beam's capacity to engrave the dot size on the photoreceptor surface that could accommodate a toner particle. Naturally if the dot calls for a 4 micron toner particle, such should be supplied or the printout quality will be affected. Toner melting point is the most important aspect, since toner is expected to bond with the paper fibers in the process of fusing. Toner is devised to have low melting point, because it will need a lot of energy if fusing temperature exceeds 220 degrees Celsius.
