that the cover is securely closed. If it is not firmly closed,
printing errors may occur when you print.

Printing a cleaning sheet
If you are experiencing blurred, faded, or smeared printouts,
printing a cleaning sheet will clean the drum inside the toner
cartridge. This process will produce a page with toner debris,
which should be discarded.
1 Ensure that the printer is turned on and in the Ready mode
with paper loaded in the tray.
2 Press and hold down the Cancel button on the control
panel for about 10 seconds.
