Sheet stacking bin fullness control system

摘要

In a shared users mailboxing system adapted to receive and stack plural print jobs of plural sheets for plural different recipients in plural mailbox bins, having a preset maximum desired sheet stacking level, with a sheet distribution system controlled by a control system for automatically variably stacking print jobs into different mailbox bins electronically assignable to different recipients, a dual mode bin stacking level indicator system for indicating to the control system when the height of the stack in a bin has reached a preset level. The control system provides a selection between the exclusive assignment of only one recipient to mailbox bins and the shared assignment of plural recipients to mailbox bins. There are two different bin stacking level estimation systems, selectable by the control system, a first sheet thickness and stapling weighted point count stack height estimation system from the sheet input count, used for the exclusive assignment of only one recipient to a mailbox bin, and a second stacking level estimation system utilizing a special physical stack height measurement system where the partial removal of print jobs by shared bin users is allowed.
