MX-4101N  ADJUSTMENTS  5 – 91
 
21-C
Printer density adjustment (low density part 
density adjustment) (Normally unnecessary 
to adjust)
This procedure is to adjust image density of low density area in
printer mode.
Adjust to reproduction (not reproduction) setting of the low density
image.
This adjustment is required in the following cases.
* When reproduction of low density image is required. When repro-
duction of low density image is not required, conversely.
* U2 trouble has occurred.
* When the MFP PWB is replaced.
* When the EEPROM on the MFP PWB is replaced.
* When there is request from the user.
1)
Enter the SIM 67-36 mode.
2)
Enter the adjustment value and press the [OK] key.
In case of increase of the image density on low density part,
increase the adjustment value. In case of increase of the
image density on low density part, increase the adjustment
value. For diluting the image density on low density part,
decrease the adjustment value.
 
21-D
Printer high density part desnsity 
correction setting (high density part tone 
gap countermeasure) (Normally 
unnecessary to the setting change)
This procedure is to adjust image density of low density area in
printer mode.
This setting normally not required. When, however, there are case
of following, change the setting.
* When a tone gap occurs on part of high density.
* When there is necessity to increase the density of the part of
high density.
* 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 67-34 mode.
2)
Select the item A, B with the scroll key.
* If a tone gap occurs on part of high density, set 0 to item A and B
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 and B.
The tone gap may occur in high density part.
