Solving Common Image Issues

Problem
Incomplete image or copy
Stitching problems – sections of image not
joining properly or parts of image
repeating or missing
Edge distortion with thick originals
One or more thin vertical lines appear in
the scanned image but are not present in
the original (paper movement direction).
Possible Causes and Remedies

Check in Nextimage that the input size is set for auto detection or set for a paper size large enough to cover the whole of the
original

Check that the original is centered if using centered scanning or fully against the keypad end of the scanner if using side-
justified scanning
Normal mode

Remove the original and switch the scanner off and then on again. Powering on the scanner runs the stitch maintenance
procedure, which should correct the problem.

Remove the original from the scanner and run the cleaning and calibration maintenance procedure
OTAC mode

The scanner stitch settings must be changed for best results when using thick media. See the section about modifying the
stitch values for OTAC earlier in this guide

Call your technical service provider if the problem persists

Image distortion caused at the edges of thick media is excluded from thick media scans by default. It can be included in the
scan by turning the exclusion feature OFF in Nextimage
Dirt, glue or dust on the scan glass

Clean the scan area and rollers

Particles from dirty documents can be carried into the scan area and remain on the scan glass before rolling away. Wipe
badly contaminated documents with a dry lint-free cloth before feeding them into the scanner. These lines are usually green

The scanner may have been calibrated with a dirty glass or white background last time and it has memorized the dirt specs.
Clean the scanner then use WIDEsystem to recalibrate the scanner. These lines are usually white

If the glass plate or white background are badly scratched, replace them following the instructions in this guide.

The calibration sheet might be creased, damaged or worn out. Obtain a new sheet and recalibrate the scanner
