Stacking height estimation correction system

Abstract

In a mailboxing system receiving and stacking plural print jobs of plural sheets, of differing sheet thicknesses, for plural different recipients in plural print job storage mailbox bins having a preset maximum sheet stacking capacity, with a stapler system for selectively stapling together the print jobs, the mailboxing system having a sheet distribution system controlled by a control system for automatically variably directing and stacking into selected mailbox bins the respective print jobs of different recipients, with a bin stacking level estimation system for indicating to the control system that the height of the stack in the mailbox bin will reach a preset stacking level, the bin stacking level estimation system is a point count stack height estimation correction system including a counting system for accumulating a point count of the number of sheets being directed by the sheet distribution system to the selected mailbox bin, a sheet thickness factor input system for inputting sheet thicknesses point count correction factors to the point count to correct for the differing sheet thicknesses of the job sheets being so directed, and a staple buildup factor input system for inputting staple buildup point count correction factors to the point count to correct for the number of stapled sets of job sheets being so directed. The point count stack height estimation correction system automatically corrects the point count with the sheet thicknesses and the staple buildup correction factors to more accurately estimate the stack height of the total stack of sheets to be stacked in the selected mailbox bin.
