You can keep the machine in optimum condition by cleaning it on a regular basis. It is a good idea 
to clean the drum unit during this routine. Avoid using thinners or other organic solvents to clean the 
machine and do not use water.

Unplug the machine and lift the document cover. Clean the glass platen and white film with 
methylated sprit on a lint-free cloth.

Lift the ADF unit. Clean the white roller, and the glass strip under the roller with methylated sprit 
on a lint-free cloth.
