Message Types
Status Messages
Status messages reflect the current state of the printer. They inform
the user of normal printer operation and do not require user
interaction to clear them. They change as the state of the printer
changes. Whenever the printer is ready, not busy, and has no pending
warning messages, the status message READY is displayed if the
printer is online. If the printer is offline, the message OFFLINE is
displayed.
Warning Messages
Warning messages inform you of data and print errors. These
messages typically alternate with the READY or OFFLINE messages
and remain displayed until you press
G O . If CLEARABLE WARNING
is set to JOB in the printer’s configuration menu, then these
messages are cleared by the next print job.
Attention Messages
Attention messages inform you that some action must be taken, such
as adding paper or clearing a paper jam. For certain errors, the
printer continues printing without user intervention. If AUTO
CONTINUE is set to ON in the configuration menu, the printer will
automatically attempt to return online.
Critical Error Messages
Critical Error messages inform you of a device failure. You can clear
some of these messages by turning the printer off and then on. These
messages are not affected by the AUTO CONTINUE setting. If a
condition persists, service is required.
