MANUAL FEED BED ASSEMBLY Section 5
5.1 .......Feed Belt - Removal
Remove the sidelay as described in section 4, remove the four
screws securing the conveyor idler shaft brackets and remove the
idler shaft assembly.
Remove the four screws securing the conveyor drive shaft bearing
housings and remove the drive shaft as an assembly.
Note ........Take care not to lose the roller retaining brackets or the
torque disc (from the coupling), when removing the
shafts. (See Fig. 6.11)
Remove the counter sensor and it’s bracket from the drive end
stiffener and remove the six screws securing both stiffeners to the
feed bed, (do not remove the screws which secure the insert to the
stiffeners), then carefully draw the insert and stiffeners from the
machine and remove the feed belt.
Note ........On re-assembly, fit the new belt according to the
direction arrow on the reverse side of the belt.
5.2 .......Counter Sensor
The counter sensor is located beneath the feed bed as shown in
fig. 5.11 and its alignment is checked as follows:-
Remove the control box lid (see section 13) and set a volt meter to
read 5 Volts DC.
Connect the positive lead to TP3 and the negative lead to TP1 on
the counter PCB. (see fig 13.12)
The signal should rise to 5.0 Volts DC when the detector is not
reflecting, (ie when covered by a sheet of paper), and drop to less
than 0.5 Volts DC when reflecting, (no paper).
The detector and reflector must be cleaned and the reflector
adjusted to obtain the lowest value when reflecting, (typically 0.2
Volts).
