When using a printer it is usually necessary to replace a complex toner cartridge, containing the photoconductor drum and peripheral parts, every few thousand pages. Instead, KYOCERA has implemented a long-life design concept utilizing various ECOSYS technologies, including a-Si (amorphous silicon) drums, so that only the toner needs to be regularly replaced. As a result, as many as 300,000 pages can be printed with having to replace anything except toner, significantly reducing both waste and cost.
