Scan Quality (Image Displayed on the Monitor) Is Poor

1. Check 1 If the image is jagged, increase the scanning resolution, or select TIFF or PNG in Data Format of the Settings dialog.

   • Resolution
   • Settings Dialog

2. Check 2 Set the display size to 100 %.

   Some applications do not display images clearly if the display size is too small.

3. Check 3 Clean the platen and document cover.

   For the cleaning procedure, click Home to return to the top page of the Online Manual for your model and search for "Maintenance."

4. Check 4 If moire (stripe pattern) appears, take the following measures and scan again with IJ Scan Utility Lite.

   • Set one of the following settings in the Settings (Document Scan) dialog, Settings (Custom Scan) dialog, Settings (Scan and Stitch) dialog, Settings (COPY) dialog, or Settings (SEND) dialog of IJ Scan Utility Lite, and then scan from the IJ Scan Utility Lite main screen.

     • Set Source Type to Magazine and set Color Mode to Color
     • Select the Reduce moire checkbox in Image Processing Settings
     • Settings (Document Scan) Dialog
     • Settings (Custom Scan) Dialog
     • Settings (Scan and Stitch) Dialog
     • Settings (OCR) Dialog
     • Settings (E-mail) Dialog
     • Settings (COPY) Dialog
     • Settings (SEND) Dialog

     Note

     • If moire appears when you scan a digital print photo, take the above measures and scan again.

   Check 5 When a thick book or similar item is scanned, white spots, streaks, or colored patterns may appear in scan results due to interference from ambient light. In that case, cover your scanner with black cloth or the like.
