2.3.6 Paper Detection Mechanism
(1)
Cut sheet detection/Rear feed detection(See Figure 11.)
When a cut sheet is inserted or a continuous form is fed by the tractor, the sensor arm
is pushed down by the paper and rotated. This moves the end of the sensor arm away
from the paper sensor that it has blocked, and the paper sensor detects “ON.”
(2)
Bottom feed detection(See Figure 12.)
When paper is fed from the bottom, the bottom sensor lever is pushed down by the paper
and the bottom sensor detects “ON.”
When the tail end of paper has passed the bottom sensor, the sensor lever returns into
position and the bottom sensor detects “OFF.”
