Abstract

A sheets sets compiling and stacking system for the output of a printer, in which the seriatim output of printed sheets may be accumulated and neatly stacked on a temporary sheets supporting system until the desired number of sheets for that set (e.g. all the pages of a collated document) is accumulated (compiled). The temporary sheets supporting system may then automatically open to drop each completed or compiled set of sheets, but with positive alternate side set clamping control against sheet scattering or skewing, dropping only one side of one set at a time, by a short distance, down onto a multiple sets stacking system, such as a self-lowering elevator stacking tray, so as to provide reduced set scattering or skewing of the sheets within the sets, and/or between sets.
