4-2 Service Tests HP DesignJet CP Series Printers
Introduction
This chapter explains how to use the built-in Service Tests (Diagnostics) and
what to do if the tests fail. 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
Initialization Sequences
Whenever the the Printer is switched on, it automatically performs a series
of internal self tests and mechanical initialization sequences. If the Printer
is switched ON in Service Mode, the front-panel display will show a code
next to the message “Initializing”. These codes refer to the part which the
printer is testing at that moment. If any of these parts fail, a system error
will appear and you should consult the System Error Codes
' Chapter 2.
