Charging and discharging the optional battery pack

Charging

Attach the connector end of the AC adapter into the AC power receptacle on the back of the battery case.

Plug the other end of the AC adapter into an electrical outlet. The CHARGE light blinks as the battery pack charges.

When the battery is fully charged, the CHARGE light turns off.

Discharging the battery pack

It's a good idea to let the battery pack completely discharge before you charge it. This will optimize the charge capacity of the battery pack.

If you notice the printer is printing fewer pages with a full charge, you can initiate a complete discharge process. First, make sure the battery pack is installed in the battery case, and make sure the AC adapter is attached.

Press the Refresh switch using such as a ballpoint pen.

The Refresh light blinks during the discharge process. This process takes about 10 hours.

When the battery pack is completely discharged, the CHARGE light begins blinking as the battery pack automatically starts recharging.

Note : You can still print while the battery pack is discharging.
