a. Adjustment procedure
1)
Enter the SIM 46-23 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.
NOTE: Do not change the setting values of item C, D, E and F. If
these values are changed, density of the high density part

* 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
SIDEA:LOW)". When adjusting density on high density part,
select "D (COPY SIDEA:HIGH)".

select "D (COPY SIDEA: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.
