MX-M1100  ADJUSTMENTS  6 – 57
By this procedure, the service target is revised. 
It is recommended to keep and store the adjustment pattern 
adjusted and printed with Sim. 46-16. By using this adjustment pat-
tern, the same copy density and gradation target can be registered
to another machine. 
It’s also useful to re-register the service target data.
Do not fold it and keep it under the circumstances which protect it
from discoloration and dirt. The service target data are basically
registered immediately after the copy density and gradation adjust-
ment (Manual) with Sim. 46-16.
The correctness of the service target data can be judged as follows.
Select the service target with Sim. 46-24 and execute the copy
density and gradation adjustment, and check the adjustment result.
When the result is unsatisfactory or abnormal, the registered ser-
vice target data may be improper. This may be caused when an
improper adjustment pattern was used or when a registration error
has occurred (Sim. 63-7).
b. Setting procedure
(Setting procedure of the copy density and gradation as the
service balance target)
1)
Use Sim. 46-16 (Copy density and gradation adjustment (man-
ual adjustment) mode) to print two sheets of the adjustment
pattern.
If the copy density and graduation is shifted from the standard,
an adjustment is required. If not, an adjustment is not required.
When an optional copy density and graduation is requested by
the user, make an adjustment.
2)
Enter the Sim. 63-7 mode. 
3)
Press [SETUP] button.
4)
Set the adjustment pattern which was properly adjusted and
printed with Sim. 46-16 (Manual copy density and gradation
adjustment) on the document table. 
Note that the adjustment pattern which was printed by another
machine may be used. 
Set the adjustment pattern so that the light density section
comes on the left side. Place 5 sheets of white paper on the
adjustment  pattern.
5)
Press [EXECUTE] button. 
The adjustment pattern is scanned.
6)
Press [REPEAT] button, set the second adjustment pattern on
the document table, and perform the procedure 5) again.
The target density setting level for each density level can be
checked. Check to confirm that the setting level is increased
from B to O gradually. If there is no change or change is
reversed, it is judged as abnormal. In case of an abnormality,
perform the procedure again. 
7)
Press [OK] button.
The density and gradation of the adjustment pattern used in
the procedure 5) is set as the service target.
(How to set the service target to the same density and grada-
tion of the factory target)
NOTE:
This procedure must not be executed when the copy density and
gradation was adjusted with Sim. 46-16 to a unique copy density
and gradation requested by the user and it was registered as the
service target with Sim. 63-7.

4)
Enter the adjustment value with 10-key, and press [OK] button. 
When the adjustment value is increased, the density is
increased. When the adjustment value is decreased, the den-
sity is decreased.
When the arrow key is pressed, the color densities selected
with the color keys are collectively adjusted.
That is, all the density levels (points) from the low density point
to the high density point can be adjusted collectively.
When [EXECUTE] button is pressed, the adjustment pattern is
printed out.
Though each density level (point) can be checked with the
printed adjustment pattern, it is more practical to make an
actual copy (in the Text/Printed Photo mode (Manual)) and
check it. 
 
11-E
Copy density and gradation adjustment 
(DSPF mode) (Individual adjustment for the 
low density area and the high density area)
This adjustment is performed when there is a difference between
the copy density in the document table mode and that in the DSPF
mode.  
The adjustment result is reflected on image send in other than the
copy mode and the image density and gradation (DSPF mode) in
the FAX send mode. 
1)
Enter the Sim. 46-9 mode. 
2)
Press [OC] button to adjust the front surface copy density, or
press [DSPF] button to adjust the back surface copy density,
and select the adjustment mode. 
3)
Select the mode with the scroll button.
The adjustment in the low density section and that in the high
density section can be performed separately.
4)
Enter the adjustment value with 10-key, and press [OK] button.
When the adjustment value is increased, the density is
increased. When the adjustment value is decreased, the den-
sity is decreased.
5)
Press [CLOSE] key in this simulation mode to jump to the nor-
mal copy mode. Make a copy and check the adjustment result.
Since the test chart for servicing cannot be used with the
DSPF, use another document and make a copy. 
(How to make a copy)
Front surface mode (Image scan by the CCD on the docu-
ment table side): 
Set a document in face-up on the DSPF document tray, and
make a copy in the simplex-simplex surface mode.
Back surface mode (Image scan by the CCD of the DSPF
unit):  
 
Set a document in face-down on the DSPF document tray, and
make a copy in duplex-simplex surface mode.
Switch the simulation mode and the normal copy mode alter-
nately, and adjust and check the adjustment result.
Repeat steps 3 to 5 until an acceptable copied image density
is obtained.

adjustment
(1) Precautions before the printer image quality adjustment 
(Before checking the printer density and gradation, be sure to per-
form the following procedures.)
Before execution of the printer image quality adjustment, the printer
density and gradation adjustment must have been completed prop-
erly.
In normal cases, however, it is not required to frequently adjust
image quality. In case of a trouble, adjustment is required.
