Testing the Power Adapter and Battery

To verify that the printer's internal battery charger is functioning properly, perform the following steps.
Test the power adapter (100-240VAC/50-60Hz, 12/24VDC adapter) with a voltmeter to verify that its
output voltage is 9 VDC.
Connect the power adapter to a power source and then connect it to the printer.
Verify that the printer's Battery Indicator is illuminated. If illuminated, the charging circuit is
functioning properly.
Note: If the battery is already fully charged, the Battery Indicator will turn off after a short time.
After the battery has been charged for five minutes, disconnect the power adapter.
Perform a printer Self-Test.
Make sure the printer is turned off.
o
Press and hold the Paper Feed Button while turning the printer on.
o
If the printer successfully prints the Self-Test, the battery is functional. If the Self-Test does not
complete and the printer turns itself off, repeat this test with a known good battery.
Once this test has completed successfully, allow the battery to fully charge. At the end of this time the
Battery Indicator will turn off.
If the printer and battery do not appear to successfully pass these tests, refer to the Troubleshooting section for
possible causes and solutions.
Note: This test only verifies that the power adapter, the internal charging circuit, and the battery are
functioning properly. This test does not provide a valid indication of the relative capacity of the battery
or how long it may hold a charge.
