USING SERVICE PROGRAM MODE
Function/[Setting]
Selects the gamma table used for linear adjustment by the
mode selected by SP4-921.
[0 = Linear / 1 = 16-bit gray] IP
Selects the value of the center ID adjustment notch for the
ID adjustment LEDs. Applies only to the mode selected by
SP4-921.
[–1 = Light / 0 = Normal / +1 = Dark]
Normally the center notch is 3 (range 1–5). If –1 is
selected, each notch shifts down (becomes lighter). If +1
is selected, each notch shifts up (becomes darker).
Adjusts the image sharpness processing (MTF and
smoothing coefficients) for the mode selected by SP4-
921.
[–2 ~ 2 / 0 / 1/step] IP
Higher values produce greater sharpness.
Adjusts the texture removal threshold for the mode
selected by SP4-921. IP
[0 ~ 4 / 0], where:
0: The mode's default value is used.
1: Fixed threshold.
2: Varying threshold (low variance)
3: Varying threshold (medium variance)
4: Varying threshold (photo error diffusion)
Adjusts the line width correction algorithm for the mode
selected by SP4-921. Positive settings produce thicker
lines; negative settings produce thinner lines.
[–2 ~ 2 / 0 / 1/step] IP
Selects the dot erase level for the mode selected by SP4-
921. Higher settings provide greater erasure.
[–2 ~ 2 / 0 / 1/step] IP
Not effective on this machine. DFU
Selects the bad-dot correction method used by the mode
selected by SP4-921.
[0 = selected mode's default / 1 = off / 2 =1-dot correct /
3 = 2-dot correct / 4 = 3-dot correct / 5 = 4-dot correct]
DFU (Not effective on this machine.)
