Troubleshooting

4.1 When the ERROR LED is Flashing

Confirm the LED flashing patterns by referring to the table below, and try the recovery
methods.

(*1) The head high/low temperature error is in the expected range of temperature changes and it is not a failure.
(*2) "All the covers" includes the roll paper cover, carriage cover, scanner cover, and scanner unit.
When paper or a card is jammed, remove it, and send the error recovery command. If the recovery
command is sent with paper or a card still jammed, the printer goes in the error status again immediately after
error recovery. (See Section 4.2, "When Paper/Card is Jammed," on page 4-3 for removal of jammed paper.)
Note:
When paper other than roll paper is selected as the paper source, if the error recovery command is sent, the
printer releases the sheet and waits for the sheet to be removed.
