Installing the Time/Date
Battery
A time/date battery is provided as an
accessory to be used for backing up the touch
panel display time. The battery will maintain
the settings for the internal clock. The battery
will be consumed even if the printer is not
used for a long period of time.
a
Press and hold the (Power) button to
turn the printer off, and then disconnect
the printer from the AC power outlet. If
the rechargeable Li-ion battery
(optional) is installed, remove the
rechargeable battery.

Press the cover release lever on either
side and lift up to open the RD Roll
compartment top cover.

Using a coin or similar object, slowly turn

direction of the arrow on the battery
cover until it stops, and then remove the
time/date battery cover.

Install the battery.
NOTE
When removing the battery, press part A,
shown below, to release the battery so
that it can easily be removed.
 Only use recommended batteries in
the printer. Other batteries may
cause damage to the printer.
 Dispose of the battery at an
appropriate collection point, not in
the general waste stream. In
addition, be sure to observe all
applicable federal, state, and local
regulations.
 When storing or discarding the
battery, wrap it (for example with
cellophane tape), to prevent it from
short-circuiting.
