2. Paper Empty Detection
The paper empty detector (C2PED) checks whether there is paper in the tray when the tray is lifted and stopped at a position where it can feed
paper, as well as during paper feed operation.
paper, as well as during paper feed operation.
3. Paper Size Detection
The size of paper contained in each tray is detected based on the
status of desk rear edge detectors (switches) 1 to 4 as well as on
the destination-specific settings.

4. Paper level detection
The paper feeder detects the amount of paper remaining in the tray as one of four levels , and displays the level it has detected.
The paper feeder determines the remaining paper level based on how many times the paper level detector turns ON during the time between
the start of the lift-up of the paper feed tray and the activation (turning ON) of the upper limit detector.
