b. Continuous forms fed via push tractor
The top of continuous forms is detected by sensor B (detailed in Figure 5.11) and by feeler 1 linked to sensor C,
an interrupt sensor.
The feeler 1's movement is transmitted to the sensor shield lever. When there is paper, the paper pushes down
feeler 1 and the shield lever opens the sensor light path.
Paper end is detected by feeler 2 on the tractor unit. It is approximate 80 mm from the print position.
