Possible Cause
The settings of the computer monitor
are wrong.
The scanning glass is dirty.
The scanning resolution settings,
combined with patterns within the
scanned image, may cause this
problem.
If the length of a document is less than
about 148 mm, feeding speed control
will be activated for exiting
documents; this is normal behavior.
Remedy
Adjust the computer monitor settings.
Clean the scanning glass. (page 48)
Change the scanning resolution, and
perform scanning again.
