Solving Problems
You can’t print scanned images,
or the printed image looks
garbled.
■ Make sure your printer is
securely connected to your
computer and that you’re using
the correct cable.
■ Make sure the correct printer is
selected in your printer
software.
OCR scanning produces poor
character recognition.
■ Select OCR as both the Image
Type and Destination .
■ Select Text Enhancement
Technology for the Black and
White Option in the Image
Type window.
■ Adjust the Threshold setting in
the Image Controls window.
The image doesn’t scan, or you
can only scan a few dots.
■ Make sure the document is face
down on the document table.
■ If you’re using an automatic
document feeder, make sure the
original document is inserted
face up.
■ If you’ve selected OCR as your
Image Type , select None for
the Black and White Option
in the Image Type window.
Then adjust the
Threshold
setting in the Image Controls
window.
Or try changing the
Image
Type from OCR to Line Art ,
then adjust the Threshold
setting.
You’re using a transparency unit,
and the colors of your negative
film preview look strange.
■ Make sure you’ve selected TPU
for Neg. Film as your
Document Source .
■ The scanner perceives the film
guide’s frame as white, which
alters the exposure of the
scanning area and makes the
preview appear darker. To see
the correct colors, do a zoom
preview on an area toward the
center of an image.
■ If you see light vertical lines on
the scanned image, the TPU
calibration area may contain
dirt or dust. Clean the
calibration area with a lint free
cloth.
