Scan Quality (Image Displayed on the Monitor) Is Poor

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.

See[Adjusting Color Mode and Output (Scan) Resolution]

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.

• 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

• Windows 7:

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).

Check 6: Clean the platen and document cover
