Recoverable errors
Although normal printer operation is not possible after a recoverable error occurs, this is not a
printer malfunction. These errors can be recovered easily by turning the power on again or
sending an error recovery command from the driver after eliminating the cause of the error.

Autocutter error
Note:
The error recovery command is valid only if a recoverable error (excluding automatically recoverable
errors) occurs. If a recoverable error occurs, the printer recovers from the error upon receipt of an error
recovery command from the driver after the cause of the error is eliminated. Turning the printer's power
off and on is not required.
Unrecoverable errors
Normal printer operation is no longer possible when unrecoverable errors occur. The printer
must be repaired.
