Solution
C
A visible stitching error
appears typically as a column
of broken lines between 2
cameras. Normally it can be
solved by running Scanner
Maintenance, which will
perform an automatic stitching
adjustment. With some curled
or creased/crumpled originals
it is necessary to straighten out
the original to prevent it from
lifting from the glass plate.
With thick originals it can be
necessary to adjust the
stitching (stitching used for
thick originals only, set this in
scanner setup). A visible
stitching error should not be
confused with the error
message "Error 32 - Could not
stitch Camera A and B"
Solution
C
Perform Scanner
Maintenance: Cleaning and
Camera Alignment. Using
Test 20 from SCANtest 6 may
help to identify dusty/dirty
areas.
Solution
C
Try upgrading the firmware
version. See 5-33.
Solution
C
Try the following:
1 - Use Test 6: Motor Test
to check the functionality of
the Stepper Motor.
2 - Replace the Driver Board.
3 - Replace the Stepper Motor.
