There are three possible error types: automatically recoverable errors, recoverable errors, and unrecoverable
errors.
Automatically Recoverable Errors
Error
Head temperature error
Cover open error in the
middle of printing
Recoverable Errors
Error
Autocutter error
Instead of closing the roll paper cover, you can make the printer recover from the error using a
dedicated command, however, doing so will cause the printer to go offline due to a cover open error.
Unrecoverable Errors
These include a high voltage error, CPU execution error, and communication unit error. If the error persists
after turning the printer off and then on again, the printer may be defective. Contact qualified service
personnel.
If an unrecoverable error occurs, turn off the power immediately by pressing and holding the
power button until the power LED flashes or by unplugging the DC cable or power plug.
