Cleaning and
Maintenance
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 determines 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 (should be replaced at 30 k prints)
■
The multi-purpose tray cork separator (should be replaced when multi-
purpose pick roller is replaced)
■
The feed rollers
■
The auto-duplex unit rollers
■
The cabinet interior
■
The exit rollers
