When SIM 48-01 (AE) is executed, the main scanning direction
magnification ratio is automatically set. Therefore, the main scan-
ning direction magnification ratio adjustment previously described
in 5) must be made again.
(6) Sub scanning direction (scanning direction)
magnification ratio adjustment (SIM 48-2, SIM 48-5)
a. OC mode in copying
Note:
•
Before performing this adjustment, be sure to check that the
CCD unit is properly installed.
1) Put a scale on the original table as shown below, and make a
normal (100%) copy.
2) Compare the scale image and the actual image. If necessary,
perform the following adjustment procedures.
3) Execute SIM 48-2.
4) After warmup, shading is performed and the current set value of
the sub scanning direction magnification ratio is displayed on the
display section in 2 digits.
5) Enter the set value and press the start key.
The set value is stored and a copy is made.

b. RSPF sub scanning direction magnification ratio
Note:
•
Before performing this adjustment, be sure to check that the
CCD unit is properly installed.
•
Before performing this adjustment, the OC mode adjust-
ment in copying must be completed.
1) Put a scale on the original table as shown below, and make a
normal (100%) copy to make a test chart.
Note: Since the printed copy is used as a test chart, put the scale
in parallel with the edge lines.
2) Set the test chart on the SPF and make a normal (100%) copy.
3) Compare the scale image and the actual image. If necessary,
perform the following adjustment procedures.
4) Execute SIM 48-5.
5) After warmup, shading is performed.
The auto density lamp lights up and the current front surface sub
scanning direction magnification ratio correction value is displayed
in two digits on the display section.
6) Enter the set value and press the start key.
The set value is stored and a copy is made.
7) Change the mode from the duplex original mode to the simplex
original mode.
"MANUAL" lamp lights up and the current back surface sub scan-
ning direction magnification ratio is displayed in two digits on the
display section.
8) Enter the set value and press the start key.
The set value is stored and a copy is made.

(7) Off center adjustment (SIM 50-13, SIM 50-16)
a. OC mode
Note:
•
The operation of SIM 50-13 is the same as that of SIM
48-01 (Photo LED ON)
1) Make a test chart as shown below and set it so that its center line
is fit with the original guide center mark.
*
To make a test chart, draw a line on A3 or 11" x 17" paper at
the center in the paper transport direction.
2) Make a normal copy from the manual paper feed tray, and com-
pare the copy and the test chart.
If necessary, perform the following adjustment procedures.
3) Execute SIM 50-13.
4) After warmup, shading is performed and the current set value of
the off center adjustment is displayed on the display section in 2
digits.
5) Enter the set value and press the start key.
The set value is stored and a copy is made.
