Description:

• Composition: Toner is largely composed of plastic polymers that have a low melting point. This allows the particles to be melted and bonded to the paper using heat and pressure during the printing process.
• Printing Process: When a document is printed, a laser creates an electrostatic image on a photosensitive drum inside the printer. The charged toner particles are attracted to these areas on the drum, then transferred to the paper. The paper then passes through a fuser unit (heated rollers), which melts the plastic in the toner, permanently fusing it to the paper.
• Form Factor: Toner is typically housed within a replaceable toner cartridge. In some printer models, the cartridge may also include the drum unit, while in others, the drum is a separate, longer-lasting component.
• Colors: While monochrome (black) toner is common, color laser printers use a set of four cartridges: cyan, magenta, yellow, and black (CMYK) to produce a full spectrum of colors.
• Advantages: Toner-based printing is known for producing sharp, smudge-resistant text, high printing speeds, and being more cost-effective for high-volume printing needs because the cartridges last longer and the powder does not dry out like liquid ink.
