how the sensor is mounted.
• After cleaning and checking the sensor,

1.1.6 Adjusting the Speed of the
Swing Guide
If you have replaced the EEPROM
(ICS107) on the finisher controller PCB or
the swing motor (M8) or disassembled/re-
assembled parts associated with the swing
mechanism, make the following adjust-
ments:
1) Set SW973 on the switch PCB as indi-
cated:
ON

F05-101-14
2) Press SW976 on the switch PCB.
• The machine starts automatic adjust-
ment, and the swing guide makes sev-
eral swinging movements.
• The machine automatically adjusts the
output voltage to the swing motor drive
circuit so that the time period (T1) from
when the swing motor starts to when
the swing guide closed sensor (PI15)
goes OFF is as specified.
3) Check DSP971 to find out the result of
automatic adjustments:
• OK if 'A'.
• NG if F, F11, F1, F2, F4, F5, or F6.
4) If the result is 'A' (OK), press SW976
on the switch PCB.
• The machine accepts the new setting.
• If T1 is too long or too short, the output
voltage of the default will be stored.
5) Turn off the power.
6) Shift all bits of SW103 to OFF.
