Jan,

    Does your scanner have the virtual rescan software? If so, there is a skew
setting option in the virtual rescan software. If you have gone down that road,
then it could be the feeder rollers not turning uniformly and/or the assembly
bar (rollers attached to it) not turning uniformly.
    If the authorized service technician cannot fix the problem, then I would
check with your vendor about swapping your defective scanner for a new scanner
to resolve your problem.
