Service Tests and Utilities

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.
