adjustment 
(Manual adjustment)
This manual adjustment is used when the automatic adjustment of
SIM 50-28 cannot obtain a satisfactory result.
 
8-A
Scan image off-center adjustment 
(Document table mode)
This adjustment is needed in the following situations:
* When the scanner (reading) section is disassembled.
* When the scanner (reading) unit is replaced.
* When a U2 trouble occurs.
* When the scanner control PWB is replaced.
* When the EEPROM on the scanner control PWB is replaced.
1)
Make a copy of the adjustment chart (made by yourself) in the
adjustment mode (document table).
2)
Check the copy image center position.
If A' - B' =  1.0mm, the adjustment is not required.
If the above condition is not satisfied, perform the following
procedures.
3)
Enter the SIM 50-12 mode.
4)
Select the adjustment mode with the scroll key.
5)
Enter the adjustment value with 10-key, and press [OK] key.
The entered value is set. When the set value is increased, the
main scanning print position is shifted to the front side by
0.1mm.
6)
Press [CLOSE] key and shift from the simulation mode to the
copy mode and make a copy. Repeat the procedures of 2) - 6)

direction.
2)
Set the adjustment chart to the DSPF/RSPF.

Make a duplex copy in the normal magnification ratio from the
manual paper feed tray, and check the image position on the
front surface and the back surface of the copy paper.
If the difference is within the range of 0   2.7mmm there is no
need to perform the adjustment. If the adjustment is required,
perform the following procedures.
