•When an error has occurred
Error Status
Chapter 1 Product Overview
There are two possible error types: recoverable errors and unrecoverable errors.
Recoverable Errors
Printing is no longer possible when recoverable errors occur. They can be recovered easily by turning the
power off and then on again or sending an error recovery command from the driver after eliminating the
cause of the error.

The carriage is
malfunctioning due to a
paper jam.
Printing on the slip is not
performed correctly due to
a cover-open.
Recovery measure

Slip ejection error The slip is not ejected when
the printer feeds a specified
amount of paper.
The error recovery command is valid only if a recoverable error occurs.
Send the error recover
command to recover.
