Technical Bulletin

When Printing Black-only documents with your color laser printers, premature drum wear can occur.

The most common Black-only printing includes email abd word document printing where no color is being used.

For example, after printing 500 monochrome-only prints, an end-user will find that the page count for the K cartridge has increased by 500 pages

While C/M/Y cartridges remain the same.

However, the drums in the C/M/Y cartridges are turning even in Black-only printing. This type of printing pits elevated wear on C/M/Y drums.

Becasue no toner has been transferred, significantly reducing lubrication with the cartridge.
