6.1 Overview

This chapter provides information on how to maintain the printer in its optimum
operating condition.
Basically, servicing on the printer should be performed on-site. Be sure to strictly
observe the following precautions when servicing to avoid an accident or injury
causing the user trouble.
The power switch is installed on the secondary side of the
W A R N I N G
power circuit, so power is always supplied to the power supply
circuit even when the switch is OFF unless the power cord is
unplugged from the wall power outlet. Unless otherwise stated
(for printing or operation checks), be sure to unplug the power
code from the wall outlet before disassembling or assembling
the printer to prevent electric shock and damage to the circuit.
The Front Sensor provided for detecting open/close status of
the Printer Cover also acts as a safety interlock switch. Never
disable the switch function to prevent possible injury.
A lithium battery is mounted on the Main Board (control
circuit) for memory backup. Be sure to observe the following
precautions when handling the lithium battery.
Be careful not to short the electrode of the battery.
•
When replacing the battery, make sure to insert it in correct
•
orientation.
• Never heat the battery or plunge it into the flames.
• Do not put the Main Board directly on conductive materials.
Be extremely careful not to get the ink into your eye or let it
come into contact with your skin. If it happens, wash out your
eye or skin with water immediately. If any abnormality is
found, contact a physician.
