Menu item Sub-menu item Description
Cleaning Page Use this option to clean the product if you see toner
specks or other marks on the printed output. The
cleaning process removes dust and excess toner
from the paper path.
When you select this item, the product prompts you
to load plain paper in Tray 1 and then press the
OK
button to start the cleaning process. Wait until the
process is complete. Discard the page that prints.
NOTE: For models that do not have an automatic
duplexer, the product prints the first side and then
prompts you to remove the page from the output bin
and reload it in Tray 1, keeping the same orientation.
