    Damn.
    I'm sitting here looking at a copy of your example. What happens if you lay the original on the glass and make a copy?

    Hello mikadonovan:

    It may happen the shifting of the bands. Sometimes well defined, othertimes difused. In one ocasion the copy was good (without bands)

    thank you.

    If you lay the original on the glass and leave the document feeder open and make several copies, is your scanner movement smooth and performing a full 11x8 1/2 scan each time? You may have already done this, but I am just trying to eliminate the possibilty of a mechanical malfunction with the scanner. Also when you do this does your lamp brightness stay steady or flicker?

    The movement of the scanner is smooth. Iīm not sure if the lamp brightness stay steady or flicker. Yet I donīt replace lamp an Vib Board, perhaps iīll replace them until tomorrow.

    Could it be possible that one of your mirrors is missing it's securing clips and is just floating around in the light source unit? I ask this because the problem characteristics change between scans.

    Itīs a good sugestion, but the mirrors are firmly in place.

    As far as the mechanical side goes, make sure that your scanner motor pulley is secured to the shaft and that the tension spring is on the motor assembly to prevent the belt from slipping its teeth.

    Guicho, I am getting ready to call it day. I am very interested in this problem, so post an update on your repair. I will check back in tomorrow. I am just sorry we haven't figured it out yet. If the scanner motor components are OK, I would say were looking for an electrical malfunction. We have covered all the mechanicals I can think of.
