Errors
Errors indicate that something has occurred to prevent the printer from printing or executing other
primary functions.
Errors are classified as Table 2.3.1 according to their cause and how they are
resolved.
Table 2.3.1 Types of Error
Name
Description
Example causes
Recoverable error
An error condition that can be reset by the
user.
The printer returns to normal status
when the user removes the cause of the error.
Open cover, paper out, paper jam,
Unrecoverable error
An error condition that cannot be reset by
the user because the user cannot remove the
cause of the error.
Detector failure or motor failure
caused by aging equipment.
Error status occurs when there is some cause of error in the printer.
When the printer recognizes that
all causes of the error have been removed, it returns to idling status.
Figure 2.3.1 Error Status Transition Diagram
When the printer is in error status, the printer behaves differently than the normal idling status as
described below.
Commands for printer mechanisms, such as print requests, cannot be executed.
Indicators (LEDs/LCDs) indicate errors.
"~H(SMA,S"(Send printer operation status ): ER (error status) is returned.
"~H(SEA,E"(Send error status): the cause of the error is returned.
