The toner is an important part in the precisely coordinated process of producing printed images. Both electromagnetic properties for transferring the toner to the printing drum and to the paper, and mechanical properties play an essential role. Finally, the toner also fulfills an important cleaning and polishing function and serves as a lubricant for the complex mechanics. Kyocera toner is precisely matched to Kyocera page printers and multifunctional devices to prevent damage and to deliver flawless printing results over the long term. The toner particles are also lubricants for the complex mechanics. Unsuitable toner can significantly shorten the lifetime of mechanical parts (developer unit, drum).
