MX-B382/B402  ADJUSTMENTS  4 – 22

 

Use for setting the condition of read operation (Exposure) for docu-
ment density in monochrome auto copy mode.
When a copy with correct density is not obtained by type of docu-
ment, change the setting.
This adjustment is required in the following cases.
* When a copy with correct density is not obtained in auto mode.
* U2 trouble has occurred.
* When the MFP PWB is replaced.
* When the EEPROM on the MFP PWB is replaced.
1)

Enter the SIM 46-19 mode.

2)

Set REALTIME, STOP or PRE-SCAN to adjustment item AE
STOP COPY. For contents of each setting item, refer to below.
Change the setting value of "AE WIDTH" item to "FULL" or
"PART", in some cases.

NOTE: MODE1: High gamma (Improves the image contrast)

MODE2: Normal gamma
STOP: 
Reads the density of 3 - 7 mm area from leading edge of
document, decides the output image density according to
the density of that part. (The output image density is con-
stant at whole area.)
REALTIME: 
Reads the density of width of the document one by one,
decides the output image density according to the density
of each part of the document. (The output image density
may be not constant at whole area.)
PRESCAN: 
The densities of the all surface of document are once
scanned, and the output image density is determined
according to the average of the scanned densities. (The
output image density is even for all the surface.)
AE WIDTH FULL: 
Document density reading area in auto mode is 3 - 7 mm
(leading edge of document) x Document width. No relation-
ship to PRESCAN MODE

AE WIDTH PART: 
Document density reading area in auto mode is 3 - 7 mm
(leading edge of document) x 100 mm (width). No relation-
ship to PRESCAN MODE
Operation in auto copy mode: 
When the density of the document of the read area is light,
output image density is increased by control. When the
density of the document of the read area is dark, output
image density is decreased by control.

the scroll key.

3)

Enter the adjustment value with 10-key and press [OK] key.
When the adjustment value is increased, reproducibility of the
background and the low density image is increased. When the
adjustment value is decreased, reproducibility of the back-
ground and the low density image is decreased.

 

Use to adjust the reproducibility for the red image and the yellow
image when printing color document that included the red/yellow
image in copy mode.

value.
When the adjustment values of the adjustment items A and B
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 the adjustment item A is
decreased and the adjustment value of the adjustment item B
is increased, the copy density of red images is increased.

2)

Select the item A with the scroll key.

* If a tone gap occurs on part of high density, set 0 to item A.

The density of high density part decreases. However, the
tone gap is better.

* In case of more increase of the density on high density part,

set 1 to item A.
The tone gap may occur in high density part.

3)

Press [OK] key.

NOTE: When the value of item B (MAX TARGET) is changed, the

density in the high density section is changed.
If these values is changed, be sure to execute the copy
density and gradation adjustment ADJ 12B. (Auto adjust-
ment)

 

This setting normally not required. When, however, there are case
of following, change the setting.
* When copy in RSPF mode differs from copy in document table

mode.

* When copy density in RSPF mode is low or too high.
* When the RSPF unit is replaced.
* When the RSPF unit is disassembled.
* The carriage unit has been replaced.

2)

Select the mode to be adjusted with the scroll key.
When adjusting density on low density part, select "A (COPY
LOW)". When adjusting density on high density part, select "D
(COPY HIGH)".

3)

a. General
In the user program mode, the user can execute the auto calibra-
tion (auto adjustment of the copy density and gradation).
This adjustment is to set Enable/Disable of the above user opera-
tion with SIM 26-53.

NOTE: This setting must be set to ENABLE only when the user's

understanding on the automatic adjustment of the copy
density and gradation and the user's operational ability are
judged enough to execute the adjustment.
When set to ENABLE, give enough explanations on the
operating procedures, notes, and operations to the user.

This adjustment is required in the following cases.
* U2 trouble has occurred.
* When the MFP PWB is replaced.
* When the EEPROM on the MFP PWB is replaced.
* When the PCU PWB is replaced.
* When the EEPROM of the PCU PWB is replaced.
b. Setting procedure
1)

Enter the SIM 26-53 mode.

2)

Select ENABLE or DISABLE with 10-key.
When disabling, set to "0" (NO). When enabling, set to "1"
(Yes).
