Print quality is not satisfactory
(part 1)
Check the paper being used
■ Non-standard paper used?
Check that the paper conforms to the specifications. Refer to
"LOADING PAPER" in the operation manual for copier.
■ Are you using paper with a high moisture content?
Use paper that is in good condition, with a low moisture
content and no curling.
■ Is the paper loaded with the wrong side up?
Some types of paper have a front and a back side. If the
paper is loaded so that printing takes place on the back side,
toner will not adhere well to the paper and poor print quality
will result.
■ Are you printing on paper that has an uneven
surface?
It may not be possible to print correctly on paper with seams
such as the back of an envelope.
