Cleaning the Printer

Printing a cleaning sheet
Printing a cleaning sheet cleans the drum inside the toner
cartridge. Use this process if you are experiencing blurred,
faded or smeared printouts. This process will produce a page
with toner debris, which should be discarded.

Make sure the printer is turned on and in the ready state and
that there is paper loaded in the paper tray.
2
Press and hold Demo on the control panel for about 10
seconds until all control panel lights remain steadily lit, then
release.

Locate the long strip of glass (LSU) inside the top of the
cartridge compartment, and gently swab the glass to see if dirt
turns the white cotton black.
