Printing a cleaning sheet

If you are experiencing blurred, faded, or smeared printouts, you can clear the problem by printing a cleaning sheet, provided by your printer. You can print:

OPC cleaning sheet: cleans the OPC drum of the toner cartridge.

Fuser cleaning sheet: cleans the fuser unit inside the printer.

This process will produce a page with toner debris, which should be discarded.

2Press Menu until System Setup appears on the bottom line of the display and press OK.

3Press the Scroll buttons until Maintenance appears and press OK.

4Press the Scroll buttons until Clean Fuser or Clean Drum appears and press OK.

Your printer automatically picks up a sheet of paper from the tray and prints out a cleaning sheet with dust or toner particles on it.

Maintaining the toner cartridge

Toner cartridge storage

To get the most from the toner cartridge, keep the following guidelines in mind:

Do not remove the toner cartridge from its package until ready for use.

Do not refill the toner cartridge. The printer warranty does not cover damage caused by using a refilled cartridge.

Store toner cartridge in the same environment as the printer.

To prevent damage to the toner cartridge, do not expose it to light for more than a few minute.

Expected cartridge yield

The toner cartridge yield depends on the amount of toner that print jobs require. The actual number may also be different depending on the print density of the pages you print on, and the number of pages may be affected by operating environment, printing interval, media type, and media size. If you print a lot of graphics, you may need to change the cartridge more often.

Saving toner

To save toner, press Toner Save on the control panel. The button backlight turns on.

Using this feature extends the life of the toner cartridge and reduce your cost per page, but it also reduces print quality.
