MX-5001N ADJUSTMENTS 5 – 77
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
is changed.
If these values are changed, be sure to execute the copy color bal-
ance density adjustment. (Auto adjustment)
20-P Copy color balance adjustment (Single
color copy mode) (Normally not required)
This adjustment is used to set the color balance and the density in
the single color copy mode to the user's request.
The adjustment is made by changing Y, M, C components of each
color.
This adjustment is not required normally, but executed when there
is a request from the user.
When the default adjustment value is changed, this adjustment is
required in the following cases.
* 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 46-25 mode.
2) Select the color to be adjusted with the scroll key.
3) Select the color (YMC) to be adjusted with the color key.
4) Enter the adjustment value with 10-key.
5) Press [OK] key.
6) Press [Close] key to exit the simulation.
7) Make a copy in the single color copy mode and check the
copy.
If a satisfactory result is not obtained, return to the SIM 46-25 mode
and change the adjustment value.
Repeat the above procedures until a satisfactory result is obtained.
20-Q Copy density adjustment in the RSPF mode
(Normally unnecessary to adjust)
This setting is 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 CCD unit has been replaced.
* U2 trouble has occurred.
* When the MFP PWB is replaced.
* When the EEPROM on the MFP PWB is replaced.
