Stack Tray Delivery Paper Surface Detection, Paper Full
The surface position of the paper delivered in the stack tray is detected by the stack tray paper surface sensors (PBA101,
PBA102,PBA103). The surface of the paper delivered in the stack tray is detected by using the stack tray paper surface sensor
(upper and lower) (light-receiving) (PBA102, PBA103) to detect the on/off state of the LED light emitted from the stack tray paper
surface sensor (light-emitting) (PBA101).

Paper absence (near empty) condition
When the paper stacked in the stack tray increases, the LED light from the stack tray paper surface sensor (light-emitting)
(PBA101) is blocked. When this happens, the stack tray is lowered so that the paper surface height on the stack tray is
appropriately aligned with the paper delivered from the delivery unit (about 40 mm).
