Introduction
This chapter is a step-by-step guide to the removal and installation of the key components of the printer.
You may find it useful to tick off the steps as they are performed. Use the illustrations for 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 (see
Service tests and utilities on page 81). If the test passes, you do not
need to replace the component.
Safety Precautions
Review the instructions identified by WARNING and CAUTION symbols before you service the printer. Follow
these warnings and cautions for your protection and to avoid damaging the printer.
WARNING! Serious shock hazard leading to death or injury may result if you do not take the following
precautions:
• Ensure that the AC power outlet (mains) has a protective earth (ground) terminal.
• Switch the plotter off, and disconnect it from the power source prior to performing any maintenance.
• Prevent water or other liquids from running onto electrical components or circuits, or through openings in
the module.
Electrostatic Discharge (ESD) Precautions
To prevent damage to the printer circuits from high-voltage electrostatic discharge (ESD):
1. Do not wear clothing that is subject to static build-up.
2. Do not handle integrated circuits (ICs) in carpeted areas.
3. Do not remove an IC or a printed circuit assembly (PCA) from its conductive foam pad or conductive
packaging until you are ready to install it.
