HP DesignJet 5000 Series Printers 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. 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.
Phone Support
In certain circumstances, a Call Agent can try and troubleshoot the
Printer by requesting the Customer to perform a Service Test or
Utility via the phone. Using this process, it can be determined
whether the Printer requires any on-site maintenance. In Phone
Support the user will have access to a limited number of Service
Tests or Utilities.
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, an error code will appear. Below is a
description of the initialization sequence, describing front panel
messages and the sequence of the Print Quality LEDs, the error
messages and error codes that may appear, and the corrective action.
NOTE Because of the speed at which the initialization sequence is
performed, some of the steps described in the intialization
process may not be visible unless they are interrupted by an
error code.
NOTE Before troubleshooting error codes try the following:
n Check that the BootROM DIMM, the DRAM DIMM’s and
the Hard Disk Drive are correctly installed.
n Try powering the Printer Off and On to see if the error code
disappears.
