Service Procedures • Replacing Components
Tip: Connect a replacement Sensor to the PCB 900-198 and test before dis-
mantling the Infeed Assembly.
Procedure
1. Switch off the power and disconnect the mains input lead.
2. Remove the Infeed Assembly (see 4.6.1).
3. Cut and remove the four cable ties securing the top Infeed Sensor Cable to
the Infeed Assembly.
4. Disconnect the Infeed Sensor Cable from PL1 Socket on PCB 900-198
ASM I/F.
5. Loosen the upper plastic nut on the Sensor Housing. Pass the Sensor As-
sembly back through the hole in the Sensor Plate to remove it from the In-
feed.
6. Take the replacement Sensor Assembly and remove the upper plastic nut
from the Sensor Housing. Ensure that the lower plastic nut is wound at
least halfway down the Sensor, allowing enough thread to be exposed for
the upper plastic nut to grip once the Sensor Housing has been inserted into
the Mounting Bracket.
7. Insert the Sensor Housing through the hole in the Sensor Plate. Turn the
Sensor so that the Cable exits the back of the Housing to the left.
8. Attach the upper plastic nut and leave finger tight.
9. Place the Sensor Cable in position along the edge of the Sensor Plate.
Loosely cable tie to hold in place.
10. Pass the end of the Sensor Cable through the grommet in the Side Plate and
connect to PCB 900-198.
11. Loosely cable tie the Sensor Cable and Interface Cable to the Side Plate.
Check and adjust the Cable so as to allow enough slack in the loop at the
housing end before finally tightening the cable ties.
12. Adjust the Sensor Housing plastic locking nuts so that the Sensor pro-
trudes above the upper nut by approximately 1mm. Tighten the nuts to se-
cure the Sensor.
13. Replace the Infeed Assembly (see 4.6.1) and test.
4.8.20 Replacing the Lower Infeed Sensor (ASM & ASMN)
If the ASM starts when a booklet is not present or fails to start when a booklet
is placed into the Lower Infeed, the Infeed Sensor may be faulty. Place a book-
let over the Sensor and watch the status of LED11 on PCB 900-197. If the Sen-
