Introduction
This chapter explains how to use the built-in Service Tests and Service Utilities and what to do if any of
the Service Tests fail.
NOTE: If possible, always perform a Service Test on the component that you are about to replace,
just to make sure that is the component that has failed. If the test on that component passes, there is no
need to replace it.
Diagnostics—self test
Whenever the printer is switched ON, it automatically performs a series of internal self tests and
mechanical initialization sequences. If any of the parts fail, a system error will appear; see
System error
codes on page 41.
Phone support
In certain circumstances, a Call Agent can try and troubleshoot the printer by requesting the Customer
to perform a Service Test via the phone. Using this process, it can be determined whether the printer
requires any on-site maintenance.
Remember that the key combination for the customer to enter the Service Tests and Utilities is different
from the one that the engineer will use.
