4.8.21 Replacing the Clamp Optical Sensor
If the Clamp fails to operate it may be because the Clamp Sensor is damaged
or faulty. When a book is placed in front of the Sensor, LED15 on PCB 900-
197 should illuminate. If not, check that the Clamp area is clear of debris and
then try adjusting the Sensor position (see 4.7.4). If adjusting the Sensor makes
no difference then it will need to be replaced.
Tip: Connect a replacement Sensor to the PCB 900-197 and text before dis-
mantling the Infeed Assembly.
Procedure
1. Switch off the power and disconnect the mains input lead.
2. Remove the Side Covers.
3. Open the Top Delivery Assembly.
4. Loosen the four locking nuts from the Book Deflector Plate fixing screws
and withdraw the screws from the Side Plates.
5. Lift the Book Deflector Plate and push it back away from the clamp Sensor
Mounting Bracket. It is unnecessary to completely remove the Deflector
Plate from the machine (see Figure 4:51).
6. Remove the two Sensor Mounting Bracket fixing screws.
7. Loosen and remove the front plastic locking nut that is securing the Sensor
to the Bracket. (There is a second nut behind the Bracket that determines
the distance the Sensor protrudes from the Bracket - try not to disturb the
position of this nut as it will be a useful guide to initially set the new Sensor
position).
8. Withdraw the Sensor from the Mounting Bracket and out through the ap-
erture in the Motor Mounting Plate (see Figure 4:51).
9. Cut and remove the five cable ties that secure the Sensor Cable to the ma-
chine.
10. Disconnect the Cable from PL14 on the PCB 900-197. Remove the Sensor
Assembly.
11. Remove the front locking nut from the new Sensor and set the back nut to
approximately the same position as the old Sensor.
12. Thread new cable ties but do not tighten.
