2. Replacement of Transfer Belts
Chapter 7 Transfer Section
2.1 Replacement of Transfer Belts
• Five sets of transfer belts are used in the NR, NL, NA, NB, and NC sections.
Basically, the same procedure should be followed to replace each belt with a new
one.
(1) Detach the transfer motor,
the plate, and the belt
shown in Fig. G13. Fig.
G14 shows the pulley of
the rod without the
transfer motor, the plate,
and the belt.
Refer to "1.
Replacement of
Transfer Motors"
for details.
(2) Detach the pulley of the
rod shown in Fig. G14.
Fig. G15 shows the
condition without the
pulley.
To detach the pulley,
loosen the two setscrews
and pull it out.
(3) Loosen the bolts of Block
A (shown in Fig. G16)
located on the opposite
side and pull out Block A
and the rod as shown in
Fig. G17.
(4) Replace the belt with a
new one under the
condition shown in Fig.
G18.

3. Setting of PCB Detection Sensor Amplifiers in NA and NC Sections
3.1 Name of Each Section in PCB Detection Sensor Amplifier
3.2 Basic Operations of PCB Detection Sensor Amplifier
(1) When the power is supplied, the amplifier is set in the "RUN" mode and the "RUN"
indicator lamp illuminates.
(2) When the D-SW is pressed, the "RUN" indicator lamp flickers, indicating that the
mode selection is set ready.
Rotate the D-SW to change the mode.
(3) When the D-SW is pressed at the point where the desired mode indicator lamp
flickers, the amplifier is set in the selected mode.
When the mode indicator lamp is kept intact (flickering) for 60 seconds, the
amplifier is reset to the "RUN" mode.
3.3 Mode Types
RUN Mode : Normal Detection Mode
SET Mode : In this mode, the detection function can be set and the sensitivity can be
adjusted.
TMR Mode : In this mode, the timer function can be set and the time of the timer can be
adjusted.
ADJ Mode : In this mode, the threshold value can be changed. When the maximum
sensitivity is set (factory-adjusted at shipment), the amplifier cannot be set
in the "ADJ" mode.
