HP DesignJets 1050C and 1055CM 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.
