XEROX DOCUPRINT 4050/4090 IPS TROUBLESHOOTING GUIDE
When a jam occurs, the system controller and printer send damaged
or lost pages to the print queue. For severe jams, the Printer
Controller performs the recovery while the printer reinitiates a system
status check.
The next level of recovery is for Host Channel Unit (HCU) errors, on
channel-attached systems only. If these occur, reboot the Sun
workstation and the HCU. Job recovery restarts and resumes at the
last checkpoint held by the host.
When printing resumes following a paper jam, there is a slight
paper jam possibility that duplicate sheets may be printed or sheets may be
missing from a job. For that reason, you should check job integrity
once the job has been printed.
Follow this procedure:
1. The printer offsets the first sheet printed following a paper jam.
Locate that sheet.
2. Check the sheets immediately before and after the offset sheet
to see if there are any missing or duplicate sheets in the job.
3. Check the output for data missing from the pages.
The following figure shows all areas in which printer jams can occur.
Note: This diagram contains the jam clearance areas for both the
dual stacker (areas 8, 8A, and 9) and the stitcher/stacker (areas A
and B). This is to give you an overall perspective of the locations of
all the printer areas relative to each other. An actual printer cannot
have both a dual stacker and a stitcher/stacker.
