Description: Printed light color pages

Possible Reasons:
- Improper storage can cause the toner to become damp or run out.
- Aging of the printer’s transfer roller can also result in a lighter overall print. If only specific colors in a color toner cartridge are lighter, the aging of the transfer roller can be ruled out.
- A dirty printer laser can also cause lighter prints.
- Both aging of the printer transfer roller and a dirty laser can be verified by replacing the printer’s drum unit.
