Charging the Battery

printer sounds three short beeps. Plug the AC Adapter
into an appropriate power source. The Charge LED
turns red when charging and turns green when fully
charged. (For more information on the Charge LED, see
Using Buttons, LEDs, and Audio Indicators on page 12

A complete charge takes approximately 2 to 4 hours.

charge, unplug the power cord. Wait 30 seconds, then
replug the power cord.
