EPSON Stylus Pro 9000

4.1 Overview

This section provides disassembly and assembly instructions for the EPSON
Stylus Pro 9000. Except as otherwise noted, you can reassemble the printer by
reversing the order in which you took it apart.

4.1.1 Precautions

In addition to reading the precautions that appear throughout this chapter, read
and keep in mind the following:


To prevent electric shock or damage to the printer, always
turn off the power switch and unplug the power cable
before servicing the printer.


If you have to remove the printer housing while the printer
is on to view internal operations, be very careful around
moving parts such as the fans, gears, carriage, and
carriage drive belt.


Keep in mind that the steel carriage drive belt and cutter
blade have sharp edges and can be dangerous.


The printer is very heavy (about 200 lbs). If you need to
separate the printer from its stand or lift the printer, four
people are needed.


For safety reasons, the front cover's position, up or down,
is detected by the cover-open sensors, located under the
left and right side covers of the printer. Do not block or
modify these sensors.


If ink gets on your hands, wash them thoroughly with soap
and water. If ink gets in your eyes, rinse them immediately
with water.


Because the main board includes a lithium battery for
memory backup purposes, keep the following in mind:
—Avoid shorting the battery, which can make it very hot
or cause it to explode.
—When replacing the battery, make sure the positive and
negative sides are correctly installed.
Disassembly & Assembly


Because ink may leak from the printer when servicing ink-
related parts, remove the paper hammock and put a sheet
or cloth under the printer when performing such repairs.


Static electricity can damage sensitive printer
components, especially on the main board. Use an
anti-static wrist band or similar grounding device to
prevent static electricity buildup.


The cutter blade is very hard and can damage or scratch
printer parts. Also, it can be easily chipped or damaged.
Be careful when handling or replacing the cutter.
