Introduction 257
Removal & Installation
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.
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.
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.
4. Ground (earth) your body while disassembling and working on the Printer.
5. After removing a cover from the Printer, attach an earthing (ground) lead between the PCA
common and earth ground. Touch all tools to earth ground to remove static charges before
using them on the Printer.
6. After removing any PCA from the Printer, place it on a conductive foam pad or into its con-
ductive packaging to prevent ESD damage to any ICs on the PCA.
Required Tools
The following tools are required to disassemble and repair the Printer.
• A long Torx Screwdriver with the following attachments: T8, T10, T15, T20, and T25.
• A long thin-bladed T-10 Torx Screwdriver to remove the Primer. The blade must be longer
than 12 cm with a maximum diameter of 10 mm.
• A long thin-bladed T-20 Torx Screwdriver to remove the OMAS Sensor. The blade must be
longer than 11 cm with a maximum diameter of 4 mm.
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.
WARNING!: Serious shock hazard leading to death or injury may result if you do not take the follow-
ing 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.
