This printer is equipped with a lithium battery. When handling
the lithium battery, the following precautions should be
followed.
• When replacing the battery, replace only 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
(+) end of it with tape to prevent combustion or explosion.
• Do not recharge 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 is installed on the secondary side of the
power circuit, so power is always supplied unless the power
cord is unplugged. Unless otherwise stated, be sure to unplug
the power code before disassembling or assembling the printer
to prevent electric shock and damage to the circuit.
Always wear gloves for disassembly and reassembly to avoid
injury from sharp metal edges.
If ink gets in your eye, flush the eye with fresh water and see a
doctor immediately.
Never touch the ink or wasted ink with bare hands. If ink
comes into contact with your skin, wash it off with soap and
water immediately. If irritation occurs, contact a physician.
