Scratch
Note: A scratch is damage to the media surface caused by contact with a roller or other Printer
components. Sometimes scratches occur before the media is inserted into the Printer.
Some media is very sensitive to surface abrasions. Contact between the Pinch Rollers, the Paper Feed Roller, and
the media is necessary to support and move it. If the media’s coating is too fragile, the Pinch Rollers (the Rollers
that contact the media’s coating) can scratch the coating.
Inserting the scratched media back into the paper path, and compare the location of the scratch on the media to adja-
cent rollers. Check the adjacent rollers for issues.
If the Print Head makes contact with the media, it can cause scratching. Usually Print Head contact leaves ink resi-
due as well. Print Head contact is usually because of excessive media curl, or incorrect platen gap.
