Paper Misfeed Detection

(1) Outline

• A paper misfeed is detected by detecting different states of signals (H, L) of several sensors located near the paper take-up section and the Exit Paper Sensor.

• The timings of the rising and falling edges of the paper take-up-related sensors and the

Exit Paper Sensor are monitored to detect a misfeed of paper being fed through the copier.

• The states (H, L) of the paper take-up-related sensors and the Exit Paper Sensor are monitored to detect a sheet of paper left in the copier.

• All drives are brought to an immediate stop when a sheet of paper misfeed or left in the copier is detected.
