Check 1: Increase the scanning resolution if the image is jagged
Adjusting Color Mode and Output (Scan) Resolution
The data in the image you have scanned is a collection of dots carrying information about brightness and color. The density of these dots is called "resolution", and resolution will determine the amount of detail your image contains. The unit of resolution is dots per inch (dpi). Dpi is the number of dots per inch (2.5 cm).
The higher the resolution (value), the more detail in your image; the lower the resolution (value), the less detail.
Check 2: Set the display size to 100 %
Some applications do not display images clearly if the display size is too small.
Check 3: Update the calibration data
Perform calibration by scanning after setting Execute at Every Scan in Calibration Settings to ON on the Scanner tab in the Preferences dialog box of ScanGear (scanner driver). Calibration may take time depending on your computer.
Check 4: If moire (stripe pattern) appears, take the following measures and scan again
- On the Basic Mode tab of ScanGear, select Magazine (Color) in Select Source.
- On the Advanced Mode tab of ScanGear, set Descreen in Image Settings to ON.
REFERENCE
If moire appears when you scan a digital print photo, take the above measures and scan again.
- If you are using IJ Scan Utility, select Magazine for Select Source on each tab of the Settings dialog box, or expand Image Processing Settings and enable Reduce moire, then scan again.
Check 5: Check the monitor's color depth
From the Start menu, select Control Panel > Appearance and Personalization > Display > Adjust screen resolution > Advanced settings.
On the Monitor tab of the displayed dialog box, set Colors to High Color (16 bit) or True Color (32 bit).
From the Start menu, select Control Panel > Appearance and Personalization > Adjust screen resolution to display the Display Settings dialog box, then set Colors to Medium (16 bit) or Highest (32 bit).
From the Start menu, select Control Panel > Appearance and Themes > Display to display the Display Properties dialog box, then set Color quality to Medium (16 bit) or Highest (32 bit) on the Settings tab.
Check 6: Clean the platen and document cover
Clean the platen of the scanner and light source of the Film Adapter Unit, while taking care not to press the platen heavily.
Check 7: If the document is in poor condition (dirty, faded, etc.), use Reduce Dust and Scratches, Fading Correction, Grain Correction, etc. in Image Settings on the Advanced Mode tab of ScanGear
Adjusting Image Settings
Check 8: If the color tone of images is different from the original document, take the following measures and scan again
- On the Advanced Mode tab of ScanGear, set Image Adjustment in Image Settings to None.
- On the Color Settings tab in the Preferences dialog box of ScanGear, set Color Matching.
Check 9: Cover your scanner with black cloth if white spots, streaks, or colored patterns appear in scan results due to interference from ambient light
