Problems Related to the Scanning Results

Problem
Not whole image scanned
Stitching problems – Image sections
misaligned (at points between the cameras -
overlapping pixels)
Edge distortion with thick originals
Possible Causes and Remedies
1. Check in your scanning application that your size settings are either for Auto detection or correspond to the size of the whole
original.
2.
Check in your scanning application that you are loading the original correctly in relation to your choice of Center-loading or
Side-loading. If you selected Side-loading in your application then the original must be fed into the side of the scanner
starting from the 0 marking on the top ruler. If Center-loading was selected in the application then align the center of the
original with the scanner's center arrow marking.
If scanning normal paper thin media – Remove the original from the scanner, turn power off and then on to reboot so the
1.
scanner runs its self-test procedure. The self-test includes camera-stitching correction.
If scanning normal paper thin media and above procedure does not correct the problem – Remove the original from the
2.
scanner and run full scanner maintenance.
3. If scanning thick media, thick stiff originals will rest on top of the scanner rollers and thus raise a small distance over the
glass-plate. This can lead to stitching irregularities. In such cases, the stitching parameters will need to be modified. You can
modify stitching parameters through your scanning application. See the section When Scanning in Thick Media Positions in
this guide.
4. Summon your technical service provider if the problem persists.
1. Scanning thick stiff originals can give distortions when the front edge meets the exit rollers or the trailing edge leaves the
entry rollers. To omit this, the leading and trailing edges are by default skipped when in one of the extended media thickness
positions.
Leading/trailing edge skipping can be turned off/on through the scanning application's setup dialogs. If you encounter edge
distortion, control that the Leading/trailing edge skipping option is set in your application.
