(Abnormal end (Auto transition))
After completion of the operation, the simulation is canceled.
8)
Use the servicing color test chart (UK0G-0283FCZZ) in the
Text/Photo mode (Manual) to check the copy color balance/
density. (Refer to the item of the copy color balance/density
check.)
If the copy color balance and density are not satisfactory, per-
form the following procedures.
9)
Execute the initial setting of the half tone image correction.
(SIM 44-21)
10) Execute the half tone image correction. (Forcible execution)
(SIM44-26)
11) Use the servicing color test chart (UK0G-0283FCZZ) in the
Text/Printed Photo mode (Manual) to check the copy color bal-
ance/density. (Refer to the item of the copy color balance/den-
sity check.)
Repeat the procedures 9) – 11) until a satisfactory result is
obtained.
However, the number of times of repeat is limited to 3 times. If the
copy color balance and density are not adjusted to the specified
level by repeating the procedures 3 times, there may be another
cause.
Troubleshoot the cause and repair or perform proper treatments,
and try all the procedures of the print image adjustment from the
beginning.
If the automatic adjustment cannot obtain satisfactory results of the
copy color balance and density, use SIM 46-21 (ADJ M19C) (Man-
ual adjustment).
20-C Copy color balance adjustment (Manual
adjustment)
This adjustment is required in the following cases:
* When a consumable part (developer, OPC drum, transfer belt) is
replaced.
* When the CCD is replaced.
* When a U2 trouble occurs.
* When the MFP PWB is replaced.
* When the EEPROM on the MFP PWB is replaced.
* When the scanner control PWB is replaced.
* When the EEPROM on the scanner control PWB is replaced.
a. General
The color balance adjustment (Manual adjustment) is used to
adjust the copy density (15 pts for each color) of CMYK according
to a request from the user for changing (customizing) the color bal-
ance because the automatic adjustment stated above is resulted in
an unsatisfactory result or a fine adjustment is required.
In this manual adjustment, adjust only the color patch which could
not adjusted properly in the automatic adjustment.
If the color balance is improper, execute the automatic color bal-
ance adjustment in advance, and execute this adjustment for better
efficiency.
b. Note for the color balance adjustment (Manual adjustment)
1)
The print engine section must have been adjusted properly.
2)
The CCD gamma adjustment must have been adjusted prop-
erly.
3)
Set the color patch image adjustment patter on the document
table, and place 5 sheet of white paper on it.
4)
Be sure to use the specified paper for color.
5)
Before execution of the image quality check and adjustment,
be sure to execute the following corrections to set the image
forming section to the optimum state.
* Execute the high density image correction (process correc-
tion) forcibly. (SIM 44-6)
* Execute the half tone image correction forcibly. (SIM 44-26)
c. Adjustment procedure
1)
Enter the SIM 46-21 mode.
2)
Press [EXECUTE] key. (A3 or 11" x 17" paper is automatically
selected.)
The color balance adjustment pattern is printed.
3)
Check that the following specification is satisfied or the color
balance is satisfactory.
If not, execute the following procedures.
The print density must be changed gradually from the lighter
level to the darker level. The density changing direction must
not be reversed.
