Service Tests and Utilities

4-2

HP DesignJets 500, 510 and 800 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 via the

phone. Using this process, it can be determined whether the Printer

requires any on-site maintenance.

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 Chapter 2 - System Error Codes.

Entering Service Menu at Power Up - Only for Onsite Repair

If the Printer fails to initialize completely because of a System Error

and you need to use the Service Menu (Service Tests and Utilities),

the Printer can be powered up in Service Mode by pressing the Up

and Enter keys while switching the Printer ON. This will give you

access to some of the Service Tests and Utilities without having to

complete the System Initialization (if you perform some of the tests,

they will need to initialize the relevant part of the System).
