Xerox WorkCentre 450c/450cp Service Manual
Introduction
This chapter describes the tasks that a service technician must complete when responding
to a problem at a customer site. Collectively, these tasks are the Service Call Procedure.
These procedures direct you to other sections when diagnosing and repairing the Xerox
WorkCentre 450c/450cp. You should always return to this section to continue with the
Service Call Procedure.
Complete the procedures in this chapter in the order given. By ignoring the sequence of
procedures, you may diagnose a symptom incorrectly and cause the customer undue
frustration and expense.
Initial Actions are used to gather information regarding the performance of the machine
and prepare the product for servicing.
System Checks are used to verify the normal operation of the machine. In the Y/N steps
of the system checks, a Yes response will lead you to the next step. A No response will
indicate the next step to perform or will direct you to a RAP.
RAPs will provide the instructions to isolate the faulty part or provide a list of suspect
parts, when isolation is not possible.
Subsystem maintenance contains routine maintenance procedures.
Final Actions describe procedures you carry out when completing the service call.
