Troubleshooting

Use the following to troubleshoot and repair the printer:

Self-test

Use the self-test to check the operation of the control circuitry and the printer mechanism.

Troubleshooting flowchart

When the source of the problem is not clear, use the flowchart to find and replace a defective
component.

Troubleshooting table

Follow the steps outlined in this table to repair a defect whose symptoms are known.

Self-test

Initiating the Self-test

1. Insert a paper roll and a ribbon cassette in the printer, and close the printer cover.

2. Turn off the printer.

3. Turn on the printer while keeping the FEED button depressed. The self-test starts, and status

information is printed.

Self-test Standby

1. When status information printing is complete, the following is printed:

“Self-test printing. Please press PAPER FEED button.”

The PAPER OUT LED flashes alternately to indicate the standby condition.

2. Press the FEED button to continue the self-test.
