SERVICE PROGRAM MODE
Function and [Setting]
Selects the MTF filter strength in the main scan
direction in the text/photo mode. Select a higher
number for stronger application of the filter.
However, increasing the value could increase
the incidence of moiré.
[0~7 / 1 / 1 step]
0: 1/32x 1: 1/16x
4: 1/2x 5: 1x
Selects the MTF filter strength in the sub scan
direction in the text/photo mode. Select a higher
number for stronger application of the filter.
However, increasing the value could increase
the incidence of moiré.
[0~7 / 1 / 1 step]
0: 1/32x 1: 1/16x
4: 1/2x 5: 1x
Selects the MTF filter coefficient in the main
scan direction in the text/photo mode. Select a
higher number for stronger application of the
filter.
However, increasing the value could increase
the incidence of moiré.
[0~15 / 9 / 1 step]
Selects the MTF filter coefficient in the sub scan
direction in the text/photo mode. Select a higher
number for stronger application of the filter.
However, increasing the value could increase
the incidence of moiré.
[0~13 / 10 / 1 step]
Selects the MTF filter strength in the main scan
direction in the text/photo mode. Select a higher
number for stronger application of the filter.
However, increasing the value could increase
the incidence of moiré.
[0~7 / 2 / 1 step]
0: 1/32x 1: 1/16x
4: 1/2x 5: 1x
Selects the MTF filter strength in the sub scan
direction in the text/photo mode. Select a higher
number for stronger application of the filter.
However, increasing the value could increase
the incidence of moiré.
[0~7 / 2 / 1 step]
0: 1/32x 1: 1/16x
4: 1/2x 5: 1x
Selects the MTF filter coefficient in the low-
density mode.
Although selecting a larger number strengthens
application of the filter and improves contrast, it
could also increase the incidence of moiré.
