SMUDGES APPEAR ON PRINTED OUTPUT
Check Solution
Are you using paper that is not within
the specifications?
Use SHARP-recommended paper.
Using paper that is for other models or special paper that is not supported may
result in misfeeds, creases, or smudges.
- "SUPPLIES" in Start Guide
Try setting the paper type to a type that is slightly heavier or slightly lighter than
normal. (For plain paper, switch plain paper 1 to plain paper 2 or plain paper 2 to
plain paper 1.) Depending on the paper type, print quality may be improved. For
details, contact your dealer or nearest SHARP Service Department.
Are you printing on pre-punched
paper?
Take care that the image does not overlap the punch holes.
If the printed image overlaps the punch holes, smudges may appear on the
reverse side of the paper following 1-sided printing, or on both sides following
2-sided printing.
Does a message appear indicating the
need for maintenance?
Contact your dealer or nearest SHARP Service Department as soon as possible.
Remove the paper, turn it over, and
reload it. Using a different paper type
may solve the problem.
This may improve some states of paper curling.
