3) Check the following items with the check pattern.
∗
Check that the section of the greatest density of C and M in
MSR check pattern, MSF check pattern 1, and SS check pat-
tern is in the range of
±
1 with the black triangle mark as the
center reference.
If this check is difficult, perform the following procedure.
Check that the print lines of M and C in SS check pattern 2,
MSF check pattern 2, and MSR check pattern 2 coincide with
the print lines of K.
∗
Check that the print line of Y in the check (adjustment) pattern
of MSR check pattern 2, MSF check pattern 2, and SS check
pattern 2 coincides with the print line of K.
If the above conditions are satisfied, cancel the simulation and termi-
nate the adjustment.
If the above conditions are not satisfied, perform the following proce-
dures.
4) Set the printed check (adjustment) pattern on the document table.
At that time, adjust so that the white triangle mark comes to the
center of the left side of the document table, and place 5 sheets of
white paper on it.
Check that the check (adjustment) pattern is in close contact with
the document table.
5) Press the [EXECUTE] key.
The check (adjustment) pattern is scanned (read) and the image
resist adjustment is automatically performed. (It takes about 30
sec for scanning (reading) and calculation.)
The calculated adjustment value is displayed together with the adjust-
ment result (EXACT, ROUGH, ERROR).
EXACT: The adjustment has been normally completed.
ROUGH: The accuracy of the adjustment is lower than EXACT due
to dirt, dusts, and improper placing of the check
(adjustment) pattern, etc.
ERROR: Adjustment error due to erroneous scanning
When "ERROR" is displayed, check the following items and repeat
procedures from procedure 1 or perform the manual adjustment of
image resist (ADJ M9/ADJ 1/ADJ 2).
∗
The paper is not placed properly.
∗
Dirt and dust on the glass and mirrors.
∗
The check (adjustment) pattern is dirty, folded, or not in close
contact with the document glass.
When the check (adjustment) pattern is normally scanned (read), the
image resist adjustment is automatically performed and EXACT or
ROUGH is displayed, go to procedure 6).
6) Press the [EXECUTE] key.
A4 or 8.5
×
11 paper is automatically selected and a check (ad-
justment) pattern is printed.
7) Perform the same procedure as procedure 3). If the image resist
is within the specified range, adjustment is completed.
If the adjustment is repeated twice and the image resist is not within
the specified range, perform the manual adjustment of image resist
(ADJ M9/ADJ 1/ADJ 2).
If the image resist adjustment (auto) has been satisfactorily com-
pleted with SIM 50-22, there is no need to perform the following pro-
cedures.
1) ADJ M9 (Main scanning direction image resist adjustment/Main
scanning direction image magnification ratio adjustment) SIM 50-
20
2) ADJ M10 (Sub scanning direction image resist adjustment) SIM

This adjustment must be performed in the following cases:
•
When the black scanner (writing) unit is replaced.
•
When a U2 trouble occurs.
•
When the ICU main PWB is replaced.
•
When the EEPROM of the ICU main PWB is replaced.
1) Enter the SIM 50-10 mode.
2) Select H: BLACK LD MAG.
3) Press the [EXECUTE] key.
4) Check that the dimension inside the printed half tone pattern is
220mm.
Use one of the following paper sizes (A4/A3/11"

17")
5) If the dimension is not as specified above, change the set value
and perform an adjustment again.
Enter the adjustment value with the 10-key and press the [OK]
key.
