Troubleshooting

There are image quality problems that are not related to HW errors. These could be due to

either insufficient cleaning, bad calibration or limitations in the CIS technology.

Streaks running in the scan direction which seems to

appear and disappear during the scan is most likely

caused by dust. Clean the scanner and the original.

The streaks are often a darker shade of color.

Streaks that run in scan direction, that are color depen-

dent or a lighter shade of the color, are often related to

the calibration. Dust that was present in the scanner

during calibration, but has been cleaned away since.

Dust Problems

Other issues could be that the scanner simply needs to be calibrated, either because the pa-

rameter block has been erased, never been calibrated or that the scanner has been moved

around.

Stitching problem between 2 CIS modules.
