Service preventive maintenance procedure

Whenever you check, service, or repair a printer, you should perform the following
procedures. Cleaning the printer, as outlined in the following steps, assures proper
operation of the printer and reduces the probability of having to service the printer in
the future.
The frequency of use and the type of paper a customer prints on will, in large part,
determine how critical cleaning the machine is. Users of ordinary Bond paper (copier
paper) should have very few problems since this paper is smooth and relatively dust-
free. You should thoroughly inspect and clean these printers.
Ask each printer customer about the type of paper he or she uses so that you can be
sure to clean the parts of the printer that particular paper may affect. If a customer is
printing on the more unusual or dustier papers, then you should pay particular
attention to these printer parts:
The standard pick roller
The multi-purpose pick roller
The feed rollers
The cabinet interior
The exit rollers
