Scanner: Text/Chart DFU
These SP codes enhance the quality of originals scanned in the Text/Chart mode
(selected on the operation panel).
5 MTF : 0(Off) 1-15 (Weak-Strong)
Sets the MTF coefficient scanned in the Text/Chart mode. When the original
image is converted to electrical signals, the contrast is reduced due to the
influence that adjacent white and black pixels have on one another as a result of
CIS properties. This may cause very narrow bands or spacing between black and
white areas. Use the MTF adjust to correct this problem and emphasize image
detail.
