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).
