Removal and Installation

HP DesignJet 5000 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/or replace a component
or assembly, always make sure that you have performed the
relevant service test for each component as described in 4,
Service Tests and Utilities
. If the test passes you will not need to
replace the component.
NOTE
To install a component perform the removal procedures in
reverse order unless a specific installation procedure is provided.
NOTE
After removing and/or replacing a component, the relative
procedure will state whether any calibrations and/or tests are
required (5,  Service Calibrations
). 
Safety Precautions

prior to performing any maintenance.
Prevent water or other liquids from running onto electrical
components or circuits, or through openings in the module.
