Charging the Battery Pack
1 Install the new battery pack in the printer.
2 Connect the power adapter to the AC outlet, and then to the printer.
The printer starts charging the battery pack. The printer does not need to be
turned on for charging to take place.
The Charge light is lit while the printer charges the battery pack. You can
print while the printer is charging, but this will increase the time needed to
fully charge the battery pack. The Charge light goes off when the battery
pack is fully charged. The printer charges a new or completely discharged
battery in 6 hours.
Maximizing Battery Pack Performance
When a nickel-cadmium battery pack is charged multiple times without
being completely discharged, you may find that the printer begins to print
fewer pages with each charge.
If the battery pack is the primary power supply for your printer, completely
discharge and fully charge the battery pack once a month to maximize its
performance.
