2. Appendix 2: Service Program Mode
8 Contrast: 1-255
Sets the overall contrast of images scanned in the Text mode (printing).
[1 to 255/128/1]
1 (Weakest), 128 (Medium: Default), 255 (Strongest)
Note: Raising the contrast level may increase moiré
9 Ind Dot Erase: 0(Off) 1-7 (Weak-Strong)
Sets the level of independent dot erasure to improve the appearance in the backgrounds
of images scanned in the Text mode (printing).
[0 to 7/0/1]

4551 Scan Apli:Txt DFU
These SP codes enhance the quality of originals scanned in the Text mode (copying)
(selected on the operation panel).
5 MTF: 0(Off) 1-15 (Weak-Strong)
Sets the MTF coefficient scanned in the Text mode (copying). 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.
[0 to 15/8/1]
0 (Weakest), 8 (Medium: Default), 15 (Strongest)

7 Brightness: 1-255
Sets the overall brightness images scanned in the Text mode (copying).
[1 to 255/128/1]
