Chapter 13 – Troubleshooting Guide
This is caused by the paper touching the OPC drum.
421.
The paper pressure plate is not functioning properly.
a. Make sure the paper pressure plate is properly installed.
b. Make sure the mylar sheet is not damaged and is making good physical contact with
the paper.
c. Make sure the paper pressure plate spring is functioning correctly. The plate should be
spring loaded so that it pushes the paper down away from the OPC drum.
422.
The transfer charger is rising too high when it engages.
a. Make sure the dampers on the transfer charger are not missing or excessively worn.
b. Make sure the transfer charger is not engaging or rising before the paper starts to
move.
1) The engagement lever might be bent and not pulling the charger down enough when
the fuser closes. Replace the lever.
423.
The paper stock being printed is too heavy and is touching the OPC drum when the
transfer charger is engaged during printing.
a. Use a lighter stock paper during printing.
424.
The paper stock is folding as it enters the printer.
a. The paper brush is not installed in the printer. Replace the paper brush.
430.
Blurred image on the first line of the first page of a print job.
431.
The transfer charger bounces when it reaches its uppermost position. It strikes the paper
causing the toner to scatter.
a. The dampers on the transfer charger are missing. This condition produces a loud noise
when the charger engages. Replace the transfer charger.
b. The transfer charger is worn and needs to be replaced.
440.
Blurred image on the first to third line of the last page of a print job.
Under normal printing conditions, the last page of a print job is not fed through the fuser.
441.
The last page of the print job has not been fused, and is still in the printer. The fuser melts
the toner of the first few lines on the page.
a. As soon as the print job finishes, perform a form feed to fuse the last page.
b. At the end of each print job, print a blank page or include a form feed in the commands
from the host to the printer.
450.
Uneven or light print density across the page.
451.
The gap between the developer sleeve and the OPC drum is too big. This results in
uneven toner transfer from the sleeve to the drum.
