  • Sloped stack detection sensor and algorithm
    Publication number: 20070090583
    Abstract: An improved sloped stack detection system for a multi-function finisher includes a reflective sensor which suspends the conveying of stapled sets to an output tray when staple build-up in small stapled sets causes the stacked output to become sloped.

  • Stack quality monitoring algorithm
    Publication number: 20070090584
    Abstract: An improved method for monitoring stack quality in a finisher of a printer includes examining the net displacement of a compiling tray after each set has been ejected. A deviation from the normal increments of displacement for each set triggers a “tray full” condition which alerts a user to empty the tray.
