PRINTING JOBS
With the stitcher/stacker output configuration, a few sheets are
held in the stitching tray when you enter RESET. These sheets
are released when the next print job begins.
Ending a print job
The ENDJOB command signals to the system that the current
print job is the last job coming from the host. All formatted
pages in the output queue are printed. This command can only
be used in online mode.
Interrupting a print job
If you need to interrupt a job during printing for any reason, do
one of the following: use one of the three variations of the
STOP command (STOP, STOP I, or STOP O), press on
the keyboard, or press the Stop button on the printer control
console. It is important to understand the difference among
these variations.
STOP command If you enter the STOP command, the following messages display:
OS0510 INPUT stopped
OS0500 OUTPUT stopped
This command stops both input and printing.
STOP I command If you enter the STOP I command, the following message
displays:
OS0510 INPUT stopped
This command stops input, but printing continues until output
catches up with input.
STOP O command If you enter the STOP O command, the following message
displays:
OSO500 OUTPUT stopped
This command stops the printing, but input continues.
key The key on the keyboard stops both input and
printing, just like the STOP command.
Stop button The Stop button on the printer control console stops only the
printing, just like the STOP O command. Input is not affected.
What to do when the system stops printing
The LPS may stop printing because all jobs being held in the
queue require an unavailable resource. A series of messages
appear indicating that the reports that cannot be printed are
being held in the queue.
