Paper Handling (PA)

Issues with paper handling (PA) cause a range of defects, as detailed in the following
sections.
Page Marking from Paper Handling
Page Marking from Paper Handling displays as smudged ink.
Cause
This defect results when the top of the media makes contact shortly after printing.
Solution
1. Print a solid area fill plot (insert plot name) and confirm area of contact.
2. Check the area of contact on the upper clamshell features to verify that nothing is
hanging down that can contact media.
3. Verify that the media entering the print engine is flat and undamaged.
4. Verify that the media is not skewed when entering printer.
5. Verify that the platen in the maintenance module platen is free to move up fully in its
guides to the datum from the printhead.
6. Confirm that the printhead is properly seated.
PA01: Printhead Strikes
PA01: Printhead strikes commonly appear as visible smudging on the paper. These
are due to the printhead striking the paper as it passes underneath. If the printhead is
dirty, then ink transfers to the paper.
Cause
Some common causes of this defect are: media bent or curled prior to entering the
printer; pinch rollers not free to move or starwheels missing; obstruction or debris in
paper path; platen in maintenance module not properly seated.
Solution
1. If it is determined that the media is damaged prior to entering the printer, then
the damaged media needs to be removed and discarded.
2. Check that the feeder is properly adjusted to prevent media damage.
3. Check for foreign objects in the printer that can cause the media to strike the
printhead or cause a pinch roller to stop functioning.
4. Ensure that no starwheels are missing. Replace, if required.
