Scanning Using the Scanner's Control Panel
Text Enhancement:
Make blurred letters in the original clear and sharp.
❏ Edge Enhancement:
You can enhance the text edges (the border between the text and the background).
When you increase the value, the edges of thin text become black.
Decrease the value if there is too much noise in the scanned image.
❏ Threshold:
You can adjust the borderline for monochrome binary (black or white).
The black areas become larger when you increase the value, and the white areas become larger
when you decrease the value.
❏ Noise reduction level:
You can adjust the level of noise reduction (unnecessary black dots).
The higher the level, the more noise reduction is applied.
Remove Shadow:
Remove the shadows of the original that appear in the scanned image.
❏ Frame:
Remove the shadows at the edge of the original.
Correct Document Skew:
Correct skew in the scanned image.
This feature may not be able to correct documents that have been over skewed.
Skip Blank Pages:
Skip blank pages when scanning if there are any in the originals.
If the result is not what you expected, adjust detection level.
Note:
❏ Some pages may be incorrectly skipped as blank pages.
❏ This feature is not available when scanning double-sided originals that are stitched.
Automatic Feeding Mode:
Set Automatic Feeding Mode. This feature allows you to continue scanning automatically after the
originals are scanned. This feature is useful when scanning different sizes or types of originals one by
one.
Adjust the edge guides of the scanner before placing each original.
❏ On (Full-Auto): Start scanning when an original is set while the continuation confirmation
message is displayed.
❏ On (Semi-Auto): Start scanning when the Start Scanning button is pressed while the continuation
confirmation message is displayed.
