Battery Charging
Precautions
❏ The battery slowly runs down even when you do not
use the printer. Charge the battery before you run
the printer on the battery.
❏ We recommend turning off the printer when not in
use to save the battery. You can also set to turn off
the printer automatically.
❏ The battery's usable time is shorter in low
temperature environments, even if you have
charged the battery fully.
❏ You do not need to use the battery completely
before charging it.
❏ The battery may be hot right after it is charged or
used; this is normal.
❏ Charge the battery within a range of 3 to 50˚C (37.4
to 122˚F). The battery may not be fully charged or
the battery may deteriorate if you charge it in low or
high temperatures.
❏ Charging only takes place if the printer is idle, in
sleep mode, or turned off.
❏ If the battery's usable time is significantly short even
after the battery is fully charged, the battery may be
at the end of its service life. We recommend
replacing the battery with a new one.
❏ If you do not use the printer for a long time, charge
the battery on a regular basis to avoid letting it run
out. If the printer does not turn on, charge the
battery for more than 30 minutes, and then turn on
the printer again.
❏ Charge the battery before using it if it has not been
used for a long period. If the battery charging light
does not turn on, charge the battery for more than
30 minutes. If the light remains off, contact Epson
support.
Charging the Battery by
Connecting to an AC
Adapter
After installing the battery, charge the battery using the
AC adapter.
Connect the power cord to the AC adapter, connect the
AC adapter to the printer, and then plug in the power
cord.
Note:
❏ The battery charging light turns on when the battery
is charging, and turns off when the battery charge is
finished.
❏ It takes approximately 5.0 hours until the battery is
fully charged.
Precautions on Storing
and Disposing the Battery
❏ Store the battery out of children’s reach in order to
avoid troubles by swallowing.
❏ When not using the printer for a long period of
time, remove the battery from the printer and store
them separately to avoid over-discharging the
battery.
