Since the power switch is mounted on the secondary
circuit of the power supply circuit, unless otherwise
specified, always turn off the printer using the power
switch. After all moving parts have stopped, wait several
seconds and then disconnect the power cable from the AC
plug socket to prevent electric shock or circuit damage
during service operations.
The cover open sensor for detecting the open/close
condition of the front cover has an interlock switch that
functions as a safety device. Therefore, it is prohibited to
turn off this switch.
A lithium battery is installed on the MAIN Board of
this printer. Be sure to observe the following
instructions when servicing the battery:
Keep the battery away from any metal or other batteries
so that electrodes of the opposite polarity do not come in
contact with each other.
Do not heat the battery or put it near fire.
Do not solder on any part of the battery. (Doing so may
result in leakage of electrolyte from the battery, burning
or explosion. The leakage may affect other devices close
to the battery.)
Do not charge the battery. (An explosion may be
generated inside the battery, and cause burning or
explosion.)
Do not dismantle the battery. (The gas inside the battery
may hurt your throat. Leakage, burning or explosion may
also be resulted.)
Do not install the battery in the wrong direction. (This
may cause burning or explosion.)
Be careful not to let ink get into your eyes or your skin. If
ink gets in your eye, flush the eye with water, and see a
doctor if you feel discomfort in your eye.
