Scuff Marks and Smudging Issues:
Scuff Marks occur when the media makes contact with an area of the printhead that has ink on it.
Smudging occurs when the wet image, on the media, makes contact with something (most commonly the
printhead) before it is dry. This issue will also increase the chance for scuff marks.
Scuff Marks:
Here is an example of “scuff marks” that occurred when the high points on this media made contact with
the printhead.
Possible Solutions for Reducing Scuff Marks:
•
Make sure the “Head Media Guide” is properly installed.
•
Make sure media is as flat as possible.
•
Manually wipe the printhead surface, using a lint-free cloth dampened with distilled water to
remove excess ink.
•
Allow the printer to sit, powered on, for 2-3 hours to give it time to remove excess ink from the
wiper roller; or 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.
