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 37.
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.
