6.5 Print and Image Quality Problems 255
Clearing the Interior (LED Printheads) of the Printer
When you find deterioration in print image quality, clean the interior (LED printheads) of the
machine.
Important
• Clean the LED printheads periodically when you replace the waste toner bottle.
1. Make sure that the machine is not
operating, and open the front cover.
2. Rotate the release lever of the drum
cartridge cover counterclockwise.
3. Lower the cover.
Note
• You can now see the drum cartridge.
4. Slowly slide out the cleaning bars housed
within the LED printhead until it stops. The
cleaning bars are located in the cleaning
connection just under the drum cartridges
(R1, R2, R3, or R4).
Note
• Slide out the cleaning bars until you see "zzz".
Important
• Do not remove the cleaning bars from the housing.
