Solving Problems
The edges of the document aren’t
scanned.
■
Check the position of your
document. Adjust it so that the
image is within the glass area of
the document table.
■
If colors are patchy or distorted
at the edges of the image, the
document may be too thick, or
there may be outside light
interfering with the scan.
Your image scans at an angle.
Check the position of your
document. It may be placed at an
angle on the document table. Align
it so the horizontal and vertical
edges are carefully aligned with the
scales on the top and side of the
document table.
Straight lines in the image come
out jagged.
Make sure the document is aligned
with the scales on the top and side
of the document table.
