This printer is equipped with a lithium battery. When handling
W A R N I N G
the lithium battery, the following precautions should be
followed.
• When replacing the battery, replace it with a specified type
of battery. Using a different type of battery may cause excess
heat or explosion.
Dispose of used batteries according to manufacture's
•
instructions and local regulations. Contact your local
government agency for information about battery disposal
and recycling.
• When disposing of the battery, be sure to securely cover the
positive terminal (+) of the battery with a tape to prevent
combustion or explosion.
Do not charge the battery.
•
Do not use the battery if it is discolored or damaged, or if any
•
leakage of electrolyte is observed.
• Do not dismantle, solder or heat the battery. Doing so could
result in leakage of electrolyte, heat generation, or explosion.
Do not heat the battery or dispose of it in fire.
•
If the electrolyte leaked from the battery contacts with your
•
skin or gets into your eyes, rinse it off with clean water and
see a doctor immediately.
The power switch for this printer is installed on the secondary
side of the power circuit; therefore, the power is always
supplied unless the AC Cable is unplugged. To prevent electric
shock and circuit damage during servicing, make sure to follow
the instructions below.
Before removing a circuit board, make sure to unplug the
•
AC Cable from the AC outlet and confirm the LEDs are
turned off by pressing the Power button on the Operating

printer.
• Make sure not to place the removed circuit boards on the
metal and such directly.
