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 setting of the low density image.
This adjustment is required in the following cases.
* When reproduction of low density image is required.
* 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.
10-key
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. 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 is normally not required, however, in the following
cases, a change of setting must be made.
* 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.

correction
* 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) If the setting values of item C, D, E and F are changed,
density of the high density part is changed.
When these values are changed, be sure to perform the printer
color balance and density adjustment. (Automatic adjustment)
