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.
