MX-C250  SIMULATION  6 – 46

When the adjustment values of SLOPE are changed, the gamma of
the total image is changed. 
When the adjustment value of SLOPE is increased, the image con-
trast of the total image is increased. When the adjustment value is
decreased, the image contrast of the total image is decreased.
When the adjustment value of INTERCEPT is increased, the image
density of the total image is increased. When the adjustment value
is decreased, the image density of the total image is decreased.

Adjustment/Setup

Used to set the AE reactivity control.

1) Select an item to be set with 10 keys.

2) Enter the set value with 10 keys.

3) Press [OK]/[START] key. 

The set value in step 2) is saved.

Adjustment/Setup

Used to adjust the color document repro-
ducibility in the monochrome copy mode.

1) Select an item to be set with Arrow keys.

2) Enter the set value with 10 keys.

3) Press [OK]/[START] key. 

The set value in step 2) is saved.

This simulation is used to adjust the reproducibility of red and yel-
low images when copy a color document of red and yellow images
in the gray push scanning mode.

When the adjustment values of items 1 and 2 are decreased, the
copy density of yellow images is increased. When the adjustment
values are increased, the density is decreased.
When the adjustment value of item 1 is decreased and the adjust-
ment value of item 2 is increased, the copy density of red images is
increased. When the adjustment value of item 1 is increased and
the adjustment value of item 2 is decreased, the copy density is
decreased.

:

Adjustment/Setup

Used to adjust the sharpness of FAX send
images.

1) Select an item to be set with Arrow keys.

2) Enter the set value with 10 keys.

3) Determine the value and starts the test print with pressing

[START] key. 

Input small numeric value to obtain crispy image. Input large
numeric value to decrease moire.

Adjustment/Setup

Used to adjust the FAX send image density.
(Collective adjustment of all the modes)

1) Set the original on the original table.

2) Enter the set value with 10 keys.

3) Press [OK]/[START] key. 

When [START] key is pressed, the adjustment value is set and
the scanned document image is outputted.

Adjustment/Setup

Used to adjust the FAX send image density.
(Normal)

1) Set the original on the original table.

2) Select an item to be set with Arrow keys. 

3) Press [OK]/[START] key

When [START] key is pressed, the adjustment value is set and
the scanned document image is outputted.
