2-1. Paper Misfeed Detection
(1) Outline
• A paper misfeed is detected by detecting different states of signals (H, L) of several sen-
sors 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.
2-2. Paper Misfeed
When a paper misfeed occurs, the control panel shows the misfeed location and paper
