1.2 Installing and Charging the Battery Cartridge
Note: One battery cartridge is included with the printer. Similar to a cordless phone battery, the
printer’s battery must be charged before using it. For optimal performance, we recommend
charging the battery twice before initial use. Charge the battery for 3 hours; disconnect power
adaptor, reconnect and charge again. After initial charge, charge battery for 180 minutes
whenever the low battery indicator comes on or as directed by your IT team.
Extech batteries must be cycled several times to achieve maximum capacity.
To cycle a battery, fully charge it and then allow full discharge through normal
use in the printer.
1.2.1: Installing the battery
Note: Refer to
Figure 2
below to install the battery pack in the printer.
Unlock the battery door by sliding the battery door locking tab up.
Open the battery door to an angle of about 90 degrees. Do not force open.
Insert the battery as shown (non-contact end first and let contact end drop into place).
Close and lock the battery door by sliding the locking tab down.
FIGURE 2: INSTALLING THE BATTERY CARTRIDGE
Note: If paper door does not open easily, tap the printer against the palm of your hand near the
paper door hinge.
