Workarounds
This image quality problem is a product limitation. So, it has NO
solution. Anyway, due to the limited cases where the problem could
appear, large amounts of complaints are not expected.
If any customer complains about this problem, provide the
following workarounds:
Rotate the image. Remember that this problem only appears on
the scan-axis direction when there are light colors are fills in the
borders. By rotating the image, you may avoid this type of colors
in the scan-axis direction.
If using a RIP, print in bi-directional print-mode.
Circle the print with a black frame that will stabilize the
printheads before doing the print.
Ink Marks on Printouts
Problem statement:
Customers usually describe the issue as “Ink marks on printouts” or
“Ink smearing”.
These marks are not located everywhere, but at very distinct places
on the printout. Depending on their location, we have identified two
different problems that can create these marks.
As a summary:
It is very important to identify the problem very clear, because their
work-arounds are different.
It is important that you thoroughly follow the qualification steps
explained in this document in order to solve correctly the
customer’s problem.
