4555 Scanner: Drawing DFU
These SP codes enhance the quality of originals scanned in the Line Drawing
mode (selected on the operation panel).
5 MTF : 0(Off) 1-15 (Weak-Strong)
Sets the MTF coefficient scanned in the Drawing 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.
