The toner is an important part in the precisely coordinated process of print image generation. Both electromagnetic properties to transfer the toner to the printing drum and to the paper and mechanical properties play an important role. Finally, the toner has 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 multifunction devices in order to prevent damage and deliver perfect printing results over the long term. The toner particles are also lubricants for complex mechanics. Unsuitable toner can significantly shorten the life of mechanical parts (developer unit, drum).
