WAITING ON INPUT
END JOB?
WARMING UP
means...
The compiler is waiting on
incoming data for the first job in
the queue. The job may not
have an end-of-job indicator and
therefore cannot end. The
message clears if more input
arrives from the port or if you
press the Cancel key. No other
jobs can be printed until this job
has ended.
The printer is warming up.
Do this...
Wait until the job is
finished and the printer
goes idle to access the
configuration menu.
Wait. No other action
needed.
