Scanner: Text DFU

These SP codes enhance the quality of originals scanned in the Text mode
(selected on the operation panel).
5 MTF : 0(Off) 1-15 (Weak-Strong)
Sets the MTF coefficient scanned in the text 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.
