Service Preventive Maintenance Procedure

Perform the following procedures whenever you check, service, or repair a printer.
Cleaning the printer, as outlined in the following steps, assures proper operation of the

The frequency of use and the type of paper a customer prints on determines how
critical and how often cleaning the machine is necessary. Record the number of sheets
printed.

Black light protective bag
