MX-7040N  ADJUSTMENTS AND SETTINGS  5 – 63

 

This setting is normally not required, however, in the following
cases, make changes to the setting:
* When copy in DSPF mode differs from copy in document table

mode.

* When copy density in DSPF mode is low or too high.
* When the DSPF unit is replaced.
* When the DSPF unit is disassembled.
* The CCD unit has been replaced.
* U2 trouble has occurred.
* When the MFP PWB is replaced.
* When the EEPROM on the MFP PWB is replaced.

a. Adjustment procedure
1) Enter the SIM 46-9 mode.

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)

Enter the adjustment value with 10-key.
In case of increase of image density, input large numeric
value. Or in case of diluting the image density, input small
numeric value.

4)

Press [OK] key.

5)

Make a copy in the DSPF mode and check the copy.

If a satisfactory result is not obtained, return to the SIM 46-9 mode
and change the adjustment value.
Repeat the above procedures until a satisfactory result is obtained.
 

 

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

CAUTION: This setting must be set to ENABLE only when the

user's understanding on the automatic adjustment of
the copy color balance and density and the user's oper-
ational ability are judged adequate enough to execute
the adjustment.
When set to enable, operation procedures must be fully
explained to the user.
