4.1.1.2 Recoverable Errors
When a recoverable error occurs, after the cause of the error is removed, the printer
can recover from the error by receiving an error recovery command without turning off
the power:
Note:
(*1) These conditions are selected by MSW 8-5 and 8-8. When MSW 8-5 (mapping of the cover open
status) is OFF, the error does not occur and a “paper end error” occurs instead. If MSW 8-8 is ON, this
error is handled as a recoverable error.
