1.1.5 Sensor Initial Adjustment
If y have replaced any of the sensors or
the EEPROM (IC102), perform the follow-
ing adjustments:
• Inlet path paper sensor (S1)
• Buffer path paper sensor (S2)
• Lower path paper sensor (S3)
• Tray B paper sensor (S4)
• Tray A power sensor (S5)
• Punch waste sensor (S6)
1) Check to make sure that there is no pa-
per in the paper path and the sort tray.
Close the upper cover and the front
cover.
2) Dispose of the punch waste inside the
punch waste case, and fit the case in the
finisher.
3) Set SW973 on the switch PCB as indi-
cated:

F05-101-13
4) Press SW976 on the switch PCB.
• The machine starts adjustment mode.
The tray A/B also moves to the 1000-
sheet stacking position (to avoid block-
ing the tray A/B paper sensor (S4/S5)).
5) Monitor DSP971 on the switch PCB
while the machine executes automatic
adjustment if to see which sensor is be-
ing adjusted. (Table 5-101)

6) When the adjustment ends, check
DSP973 to find out the result.
• If DSP971 indicates '0', all sensors are
normal.
• If DSP971 indicates 'F', the output level
of any of the sensors is not normal.
7) Press SW975 or SW974 on the switch
PCB so that details of the result of the
adjustment is indicated.
• After the sensor number (Table 5-102),
details are indicated for that particular
sensor (Table 5-103).
• A press on SW975 moves to the next
sensor, while a press on SW974 moves
to the previous sensor.
