Printer Maintenance
• Verify that the printer’s amber CHARGING INDICATOR is illuminated. If so, the charger circuit is
functioning properly.
• After the battery has been charged for five minutes, disconnect the power adapter.
• Perform a printer Self-Test by pressing and holding the PAPER FEED button, pressing the ON/OFF
button, and then releasing them both.
• 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, turn off the printer and allow the battery to fully charge (180
minutes). At the end of this time the CHARGING 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 the battery or how long it
may hold a charge.
