Single stack height sensor for plural sheet stacking bins system

摘要: In a sheet stacking system with an array of plural bins entrances for flimsy print substrate sheets from printed output path into selected bins, feeding input bin to be stacked therein, fullness indicator indicating that the estimated height stack has reached preset allowable maximum, and control controlled by path; there is single sensing including sensor respective measurements actual in system, movable carriage moving this adjacent one another measurements, element extendable intermittent actuator then detect therein. A signal generator responsive position provide signals system.
