What causes the lines in an image?
Lines or Banding Within the Image
If the scanner is generating lines or banding within the image during preview and/or scan, below is a list of possible solutions.
Horizontal Lines: If the lines run horizontally throughout the image, it is almost definitely interference of some kind. First thing to try is reverse the cable (Astra series only, except for 2400S), trying with and without termination as well. It could also be the SCSI card itself that is causing the interference. Try reseating it in a different slot, away from other cards. Try moving the scanner itself to another location, farther away from computer components such as monitors and CPUs. If none of that works, search for the file ?prescan.dib? on the hard disk and delete it, then try the scan again. If that still doesn?t work, follow the clean uninstall and safe mode install of our software. If these troubleshooting steps do not work, it could be a physical defect within the cable that?s generating extra interference, and the cable should be replaced. If the cable has been replaced already, it may be the UDS-IS11 itself generating the interference from being defective. Replace it.
Vertical Lines: If the lines run vertically throughout the image, it is probably a hardware problem, most likely with the scanner itself. However, follow the cable-reversing instructions above, remove the ?prescan.dib? file, and try the scan again. Often, if they are thin lines they are from dust within the optics. Open the case and blow out the dust with compressed air.
