Film Sensors/Adjustments, Cont'd
Film sensor location configuration (See figure 5-1)
Film Sensor Adjustment: These sensors are adjusted at the factory and normally do
not need adjustment. However, should adjustment be required, follow this procedure:
1) Loosen the screw on each small bracket securing the sensors to the molded feed tray
adapter; the sensors may be moved up or down.
2) Locate each sensor upward close enough to the magnet opposing it so that the
machine remains in standby. Raising either magnet by inserting a film should put the
machine into the process mode. If this does not occur in either case, lower the sensor in
question until it does.
Another Method of Adjustment: Since the two Hall-Effect switches are wired in
parallel, simply short out one and position the other until it activates (allow 10 seconds
after repositioning the switch for the beeper to sound and the wait light to go off).
The easiest way to short out one switch while adjusting the other is to open the front
electrical panel and locate the beeper board. It is the smaller of the three boards, and is
located in the upper middle section of the electrical panel. Each switch is connected to
the board by means of a plug at the end of a 3 wire ribbon cable.
Unplug one switch from the board and jump the second and third pins (count left to
right) together. This completes the circuit for this switch. Now you can adjust the
position of the other one. Once this is done, plug the other switch back into the board
and adjust its position. There is no need to unplug the other one while doing this since
you have already repositioned it. The addition of some silicone caulking to each switch
will help assure that they both stay in position.
