FEEDER HEAD PROTECTION SENSOR

The feeder head is protected by a sensor from damage in the case of:
•
The feeder head foot slides from the paper stack and the feeder table automatically rises up.
•
The capacity sensor on the front of the paper stack fails.
The sensor is located under the feeder head and is close to the clamp.
If the sensor stops the machine for one of the reasons described above, do the following:
1. Switch the power off with the main power switch.
2. Remove 1 to 1-1/2 in. (25 to 35 mm) of paper from the top of the paper stack.
3. Check to see what caused the machine to stop.
The above procedure can be performed only by a technician trained by GBC Service.
If the sensor must be adjusted so that it will not prevent the normal function of the feeder head and will
stop the table movement just when the feeder head is slightly lifted around the guide bar after the
feeder (stack) hits the feeder head, the adjustment can be performed only by a GBC Service
technician.

ROTARY VALVE ADJUSTMENT

For correct feeding, it is necessary to precisely adjust the paper release from the suction cups. The
adjustment should be performed by turning the rotary valve (p). The release moment has to be 1/16 to
5/64 in. (1.5 to 2 mm) in front of the front dead center of the suction cup motion. The correct position of
the rotary valve is adjusted by the manufacturer and it is marked by a screwed hole in the hollow.
The adjustment can be performed only by a GBC Service technician.
