lights on scanner control panel fail to come on

   

    1. check that the power supply is connected to the scanner.

    2. check that the scanner is switched on.

    3. check that the scsi bus is correctly terminated.

    4. check that scanner is not in firmware download mode.

   

    red error light on the display panel indicates a failure during start up

   

    1. ensure that the normalization target is fitted correctly during calibration.

    2. ensure that the lid is closed.

    3. re calibrate the scanner.

    4. scan a 200dpi, 2 inch by 2 inch in rgb mode.

    5. if the fault persists then a service engineer is required.

   

    streaks appear on the image

   

    1. change the aperture tape if fitted.

    2. if the lines are vertical and continuous please re calibrate the scanner making sure that the calibration target is as clean as possible. you may need to load new firmware, so please check with section 6 of this manual.

   

    document twists visibly in the scanning plane as it is loaded or during scan

   

    1. check lid height setting.

    2. check that neither edge of the document is hitting the side of a pinch roller. move the document left or right prior to loading if necessary.

   

    document slips when scanning

   

    1. reduce scanning speed. if the problem persists, the document may be too heavy or slippery to be accepted.

    2. if the document is light, then try mounting it on a less slippery backing before scanning.

    3. drive motor stalls when loading.

    4. check for correct height adjustment.

   

    drive motor stalls when scanning

   

    1. reduce scanning speed.

    2. check for correct height setting.

    3. check scanner throat is clear and all surfaces are clean.

    4. if the problem persists, then document may be too heavy or slippery to be accepted.

   

    there is a vertical discontinuity in the image halfway across the whole scanner width (4260e, 3680e), or 1/3 or 2/3 of the way across the scanner (5480e, 4280e)

   

    1. carry out the auto-stitch procedure.

    if this does not solve the problem re-stitch using auto stitch function with the auto-stitch target attached to a piece of media of similar qualities to the document being scanned.

   

    there are visible color artifacts in the image that are very prominent in the horizontal direction and the scanner stops and starts while scanning.

   

    use the fractional speed function on the software to slow down the document speed and avoid the motion of stopping and restarting.

   

    horizontal artifacts in the image at approximately 2.7" or 70 mm from start or end of document

   

    attach 2.7" or 75 mm wide strip of similar media to the leading or trailing edge of the document.
