Removal and Installation

8-2

HP DesignJets 500, 510 and 800 Series Printers Service Manual

Introduction

This chapter is a step by step guide to the removal and installation of the key components

in the printer. You may find it useful to tick off the steps as they are performed. Use the

illustration at each procedure to identify the parts referred to in the text.

The procedures appear in order of removal. So the whole machine can be stripped down

by starting at the beginning of this chapter and working through the subsequent

procedures.

NOTE Before using this chapter to remove and install a new component,

always make sure that you have performed the relevant service

test from Chapter 4. If the test passes you will not need to replace

the component.
