Scuff Marks
Scuff Marks occur when the media makes contact with something (most commonly the Printhead) that has ink on it.
Here is an example of “scuff marks” that occurred when the high points (thicker/puffier areas) on this #10 envelope
made contact with the printhead.
Possible Solutions for Reducing Scuff Marks:
•
Increase the “Print Height” value, in Media Setup.
•
Make sure media is as flat as possible and folds are as tight as possible.
•
Manually wipe the printhead surface, using a lint-free cloth dampened with distilled water to remove
excess ink.
•
If possible; rotate the media and image 90, 270 or 180 degrees. Sometimes the direction of feed and the
mechanics of how the media is driven through the printer can have an effect.
•
Run “Wiper Transfer” in Wiper Menu, to reduce ink (moisture) on Wiper Roller.
•
Contact your support representative to have the wiper roller replaced.
•
Use a more suitable media (flat and uniform in thickness).
NOTICE!
It is OK to run the “Quick Clean Printhead” routine once, to see if this has any effect on improving this
issue. However, if it doesn’t help, you shouldn’t repeat this process or use a higher level cleaning routine. Over-use
of the “…Clean Printhead” routines will normally increase this issue, because the wiper roller will become more
saturated with ink with each cleaning routine; if done too frequently. An over-saturated wiper roller will leave more
ink behind on the printhead.
