REV.-A
4.1 BEFORE DISASSEMBLY
This chapter describes the disassembly procedure for replacing any of the major
components of the printer. Before disassembling the printer, be sure to read the following cautions.
DANGER
• Before disassembling, assembling, and adjusting the printer, be sure to disconnect the AC
power cord.
• Wear protective glasses to protect your eyes from the ink. If any ink comes into contact
with the eyes or a wound, wash it off immediately with plenty of water, then consult a
doctor.
• If the ink comes into contact with skin (i.c. hands), wash it off with soap and plenty of
water. If any irritation develops, consult a doctor.
• The main board of the printer is equipped with a lithium battery. Before disassembling the
main board, read the following cautions so that you can handle the battery safely. Also be
careful of its storage condition.
a. Do not store lithium batteries stacked together or with other metal parts, to prevent the
+
and - sides from making electrical contact, which could cause a short circuit.
(If a battery is shorted, a large current can flow. The battery could ignite or burst due to
the heat generated.)
b. Do not heat the battery. Do not throw it away into a fire.
c. Do not solder any portion other than the connection terminals.
(The battery might burn or burst if the internal solution leaks out or if it shorts internally.
If the solution in the battery leaks and it is left as it is for a long time, the printer
components around the battery could be damaged.)
d. Do not charge the battery.
(If it is charged, gas would be generated, and it could ignite or burst.)
e. Do not disassemble the battery, or deform it using pressure.
(The gas in the battery could irritate your throat, or the battery might
burst or ignite, and the solution might leak.)
f. Do not mount the battlery (+ and - sides reversed).
(If the
+
and --sides are reversed, the battery might ignite or burst due to a short
circuit.)
WARNING
• Before transporting or repairing the printer or printer mechanism, observe the notes indi-
cated in the repair procedure below to keep the repair personnel safe and keep the printer
clean. Also, be sure to start repairs by draining the ink, and only transport the printer under
the correct conditions.
• Please instruct customers on the precautions for transporting the printer whenever you have
a chance to talk to them.
• Use the specified tools to maintain optimal printer performance. Epson will not take
responsibility for printer parts being damaged by tools other than those specified.
• Be sure to perform the specified lubrication and adhesive application. (See Chapter 6.)
