Chapter 9 Installing and Using the Battery Pack 139
Battery Pack Capacity
With a fully charged battery pack, you may be able to print up to 180 pages
without the use of AC power. The actual printing time depends on the
complexity of the data you are printing.
Printing With a Low Battery
When you are using the battery pack and the battery starts to run low, the
printer beeps twice, displays C and 5 alternately, and stops printing. You
can press ON LINE to continue printing. After printing a few more sheets,
the printer will stop again. You can press ON LINE to continue several
times. When you finish printing, turn off the power.
When the battery becomes completely discharged, the printer beeps for
about five seconds, displays F and C alternately, and stops printing. Any
data that has not printed is lost. Press the POWER button to turn off the
printer.
To continue printing, make sure the printer is turned off and attach the
AC adapter to supply power.
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 that the printer is printing fewer pages with a full charge, you
can initiate a complete discharge process. Follow these steps:
1. Make sure the battery pack is installed in the battery case.
2. Make sure the AC adapter is attached.
3. Using a pointed object, such as a ballpoint pen, press the REFRESH
switch.
