Can not Print Correctly?
If the unit’s print quality becomes unsatisfactory, consider the following
suggestions:
J
Most paper has one side that provides better print quality than the other. If
the print quality is poor, try turning the paper over and printing on the other
side.
J
If the characters and images are blurred, make sure you’re using the correct
type of paper, and printing in the correct printing area.
J
If the reverse side of the printed page is smudged, the inside of the unit is
probably soiled with toner powder. Clean the inside of the unit with clean
soft, dry, lint-free cloth. (
Q
p. 9-3)
J
If printed images are blotched or uneven, the problem may be noise in the
phone/fax lines. Try using ECM receiving (though if the lines are very busy or
in poor condition, you may have to ask the sender to try again). See page A-8
for details on setting ECM.
Also, remember that the sending fax machine usually determines the quality of
the fax. To see if your unit is the cause of the problem, use it to make a copy: if
the copy is clear, the sending fax machine may be the problem; if the copy is not
clear, your unit may need to be cleaned.
