  • Page 24: Stitching Problems

    Troubleshooting Dust Problems 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.
