Punch Waste Full Detection

Punch waste full detection is performed by the punch waste full sensor (PBA303) at the side of the punch waste tray and the
prism inside the punch waste tray. Punch waste full detection is performed by a prism reflecting the LED light from the light-
emitting area of the punch waste full sensor (PBA303) and the light-receiving area of the sensor detecting the reflected light.
During punching, punch waste is collected in the punch waste tray. After punching is complete, if the punch waste full sensor
(PBA303) cannot receive the LED light, it determines that the punch waste is full.
Punch waste near-full detection and full detection are performed under the following conditions.
- Near-full detection
• If punch waste full is detected consecutively five times during the punch operation after punch waste full is detected
- Full detection (punch waste tray detection)
• If punch waste full is detected consecutively 1,000 times during the punch operation after punch waste full is detected
