aligned properly. The paper guides are not
pressed up against the paper
stack in the tray. Slide the paper guides against
the edges of the paper stack.
The paper has an excessive
curl. Smooth out curls in the paper
and reload the paper stack in
the tray.
The printed page is curled. The paper that was used curls
easily (as with recycled paper). Remove the paper from the
paper tray, turn it over, and
then load it again.
Change the paper.
The edge of the printed output is
dirty. You have selected paper of a
size larger than the original
(when the zoom ratio is full
size). Select paper that is the same
size as the document.
Otherwise, enlarge the print to
the selected paper size.
The original is not placed in the
correct position (when the
zoom ratio is full size). Select the same paper size as
the original. Or, reload the
paper in the same direction as
the original.
The reduction ratio selected
does not match the paper size
(when the copy is made at a
manually adjusted reduction
ratio). Select a zoom ratio that adjusts
the copy size to the size of the
selected paper. Otherwise,
make a reduced copy with a
zoom ratio that matches the
paper size.
