Gamma/Brightness/Contrast correction on scanned images

bobn0gfh — Thu, 18 Apr 2019 14:30:37 GMT

I'm the Canon MF Scan Utility with my mf249dw and Windows 10 to scan b/w documents to pdf files. The scan quality is poor compared to the same scan done with a different scanner.

Canon scan:

Other scanner:

How can I improve the quality of the image from my Canon scanner?

Hi bobn0gfh.

You can adjust the image quality settings using the Advanced mode of the ScanGear MF driver. To access the driver, open the MF Scan Utility, and then click ScanGear. A new window will open.

Please follow the steps at the link below to adjust the settings:

Adjusting Brightness and Color Settings

Is there any way to fix the presets, or do I have to do a custom scan every time I want a quality scan?

The quality settings within ScanGear are only available when scanning from the computer. There are image processing options within the preset options on the printer, but they will need to be adjusted in the MF Scan Utility. Please follow the steps at this link to access those settings:
