Abstract: Multiple sheet set compiling in a compiler of the seriatim output of printed sheets from a printer with a sheet entry position and a lateral sheet tamping system for laterally tamping the sheets being stacked in the compiler, in which the accumulated stack height of the sheets being compiled is estimated, and in response thereto the height of the top of the lateral sheet tamping system is raised to be maintained above the top of that rising (thicker) stack in the compiler, and lowered for the initial sheets stacking, and the compiler sheet entry position is also automatically raised in proportion to the increasing height of the stack of sheets being compiled in the compiler.

Abstract: A disk stacker system for delivering selectively inverted substrate assemblies into a receiving tray. By alternating inverted with non-inverted substrate assemblies or otherwise grouping inverted and non-inverted substrate assemblies, handling of folded printed material is made more efficient and packing of the folded printed material is made more dense and efficient. The disk stacker system operates by delivering selected substrate assemblies directly to the output tray and bypassing the disk stacker inverting apparatus and by delivering other substrate assemblies to the disk stacker apparatus for inversion prior to delivery to the output tray.

Abstract: A method in an imaging system for automatically selecting a copy substrate from multiple substrate trays and for improving the productivity and imaging of the copy substrates. The method includes comparison of the dimensions of the copy substrate to the dimensions of the input document in order to automatically select a copy substrate, automatically rotate digital information in order to align the orientation of input and copy documents, center imaging information onto the copy substrate, and to perform various AutoFit functions.
