CHAPTER 5 TROUBLESHOOTING
Level 3
Indicates
that the
sensor
output
level is
good.
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:
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.
Level 2
Indicates
that the
sensor
output
level is
starting to
drop.
Level 1
Indicates
that the
sensor
output
level is
near the
lower
limit for
use.
Level 0
Indicates
that the
sensor
output
level is
below the
lower
limit for
use (faulty
sensor).
T05-101-03
•
If the detail of the result is level 2, level
1, or level 0, clean the sensor and check
how the sensor is mounted.
•
After cleaning and checking the sensor,
try the adjustment once gain; if still
level 1, be ready for replacement.
•
After cleaning and checking the sensor,
try the adjustment once again; if still
level 0, replace the sensor.
8) Press SW976 on the switch PCB.
•
The result will be stored.
•
The tray A/B will move up to initial po-
sition.
9) Turn off the power, and shit all bits of
SW973 to OFF.
