the finisher controller PCB.
• LED101 will indicate the present value.
8) Press SW105 or SW106 on the finisher
controller PCB as necessary.
• Each press on SW105 increases the degree
of wrapping by about 1.74 mm.
• Each press on SW106 decreases the de-
gree of wrapping by about 1.74 mm.

6. Sensor Initial Adjustment
Perform the adjustment if you have re-
placed any of the following sensors or the
EEPROM (IC102) on the finisher controller
PCB:
• Inlet path paper sensor (S1)
• Buffer path paper sensor (S2)

• Tray B paper sensor (S4)
1) Check to make sure that there is no paper
in the paper path or on tray B. Then, close
the upper cover and the front cover.

3) Press SW104 on the finisher controller
PCB.
• This will start adjustment mode, and tray
B will move to the 1000-sheet stacking
position. (This is to prevent blocking the
tray B paper sensor (S4).)
4) See LED101 on the finisher controller
PCB to find out which sensor is being ad-
justed. (Table 5-101)

5) When adjustment has ended, find out the
result by referring to LED101.
• If LED101 indicates '0', all sensors are
normal.
• If LED101 indicates 'F', the output level of
one of the sensors is not adequate.
6) Press SW105 or SW106 on the finisher
controller PCB to indicate details of the
result.
• See Tables 5-102 and -103 for the No. of
each sensor and how details of the result
are indicated.
• A press on SW105 for a second time
moves to the next sensor, while a press on
SW106 moves to the previous sensor.
