Service Tests and Utilities
3-2 Designjet Z Series — Service Manual
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.
Diagnostics - Self Test
Initialization Sequences
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 and you should consult
2, System Error
Codes.
Phone Support
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.
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 Customer Engineer will use.
