4.8.18 Replacing the Stop Assembly
Procedure
1. Switch off the power and disconnect the mains input lead.
1. Remove the Side Covers.
2. Remove the Spirol Pin from the Adjuster Shaft (265-835).
3. Loosen the Trantorque Bush on the end of the Adjuster Shaft. Remove the
Trantorque Bush and the Flanged Pulley.
4. Lift the Adjuster Shaft out of the machine.
5. Remove the Stop Assembly (907-404) from the machine by removing the
two screws in the LH and RH Adjustment Supports and the LH and RH
Spring Mounting Brackets (see Figure 4:48). The Stop Assembly can be
withdrawn from either side of the ASM. It may be necessary to move the
Stop and the Carriage when removing the assembly, in order to gain
enough clearance.
6. Fit the new Stop Assembly.
7. Rebuild the ASM, but do not refit the Side Covers.
8. Adjust the Stop (see 4.7.7).
9. Refit the Side Covers.
4.8.19 Replacing the Upper Infeed Sensor
If the ASM starts when a booklet is not present, or fails to start when a booklet
is placed into the Upper Infeed, the Infeed Sensor may be faulty. Place a book-
let over the Sensor and watch the status of LED10 on PCB 900-197. If the Sen-
sor is functioning correctly the LED will illuminate. If the Sensor is faulty the
LED will remain off.
If the LED is lit when no book is present, ensure that the Sensor is not reacting
to reflections within the ASM. A piece of black, light absorbent tape is nor-
mally adhered to the underside of the Stacker Motor.
