2. Appendix 2: Service Program Mode
8 Contrast: 1-255
Sets the overall contrast of images scanned in the Photo mode.
[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 Photo mode.
[0 to 7/0/1]
0: Default (Off) 1 (Weakest) to 7 (Strongest)
4565 Scan Apli:GrayScale DFU
These SP codes enhance the quality of originals scanned in the Grayscale mode
(selected on the operation panel).
5 MTF: 0(Off) 1-15 (Weak-Strong)
Sets the MTF coefficient scanned in the Grayscale 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.
[0 to 15/8/1]
0 (Weakest), 8 (Medium: Default), 15 (Strongest)
6 Smoothing: 0(x1) 1-7 (Weak-Strong)
Sets the level of smoothing for originals scanned in the Grayscale mode.
[0 to 7/4/1]
0 (Weakest), 4 (Medium: Default), 7 (Strongest)
7 Brightness: 1-255
Sets the overall brightness images scanned in the Grayscale mode.
[1 to 255/128/1]
1 (Weakest), 128 (Medium: Default), 255 (Strongest)
Note: Raising the brightness level may increase moiré
