W A R N I N G
The power switch for Stylus Pro 7600/9600 is incorporated in
the secondary circuit of the power supply circuit. Therefore, the
printer is always supplied with electric power, unless the power
cable is disconnected. Before servicing, unless otherwise stated,
be sure to unplug the power cord from the wall outlet to
prevent injury, burn, and electric shocks or damage to the
circuit. In doing so, be sure to turn the printer off and wait
several seconds first and then unplug the power cord. If you
must keep the power supplied to measure voltage, be aware of
the potential for electrical shock and do all tasks with the most
care.
With the front cover open, the cover sensor stops the operation
of the CR motor and PF motor. To ensure safety, you are
prohibited from disabling this interlock function.
A lithium battery for memory backup is installed on the main
circuit board of Stylus Pro 7600/9600. To prevent accidents
caused by the battery, never fail to observe the following
instructions when serving the main circuit board:
• 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 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. (This may 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
caused.)
• Do not short-circuit the terminals of the battery. Do not put
the battery on a conductive table in such a way that the
terminal face comes in contact with the table.
• Do not remove and install the battery. Do not install the
battery in the wrong direction.
• Do not heat the battery or put it near fire.
