Maintenance and Troubleshooting

Testing the Power Supply 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 supply 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: that 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 supply.

•Perform a printer Self-Test.

oMake sure the printer is turned off. The power indicator will be off and the LCD Display will be blank.

oPress and hold the Paper Feed Button.

oContinue holding the Paper Feed Button and turn the printer on using the Power Button until “Printing Current Menu Values” is displayed.

•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.

Note: If the printer is turned on, the battery status shown in the bottom right corner of the LCD display will always show a “full” battery whenever the printer is connected to the power supply.

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.
