This adjustment is needed in the following situations:
• The original size sensor section has been disassembled.
• The original size sensor section has been replaced.
• U2 trouble has occurred.
• The scanner control PWB has been replaced.
• The EEPROM on the scanner control PWB has been replaced.
1) Go through the modes specified in Simulation 41-1.
2) Gradually turn over the original detection arm unit in the arrow
direction, and loosen the original cover switch actuator adjusting
screw so that the OCSW indicator changes from inverse video to
normal video when the arm unit top reaches a height of 32±0.5mm
from the table glass. Then move the actuator to adjust its position.
(If the original cover switch turns on in improper timing, the original
detection mechanism mail fail to operate correctly.)

1) Go through the modes specified in Simulation 41-2.
2) Open the original cover. With nothing placed on the original table,
select NO ORIGINAL using the numeric keypad.
3) Press the Start key
This sets the sensor level with no original detected.
4) Set A3 (11" x 17") paper on the original table, and select A3 ORIG-
INAL using the numeric keypad.
5) Press the Start key
This sets the sensor level with an original detected.

This adjustment is needed in the following situations:
• One or more parts of the DC main power supply unit have been
replaced.
• One or more parts of the DC sub power supply unit have been
replaced.
(24 V supply voltage adjustment)
1) Apply a digital multi-meter to the DC main PWB 24 V line (CN3, 1
pin) and GND (CN3, 4 pin).
2) Turn RV202 on the DC main power supply PWB so that the volt-
age is 24 V.
(38 V supply voltage adjustment)
3) Apply a digital multi-meter to the DC main PWB 38 V line (CN8, 1
pin) and GND (CN8, 4 pin).
4) Turn RV201 on the DC main power supply PWB so that the volt-
age is 38 V.
(12 V supply voltage adjustment)
5) Apply a digital multi-meter to the DC sub PWB 12 V line (CN4, 1
pin) and GND (CN4, 6 pin).
6) Turn RV102 on the DC sub power supply PWB so that the voltage
is 12 V.
