Abstract
Abstract 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.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
285 words
In a shared users plural bins mailboxing system adapted to receive and stack plural print jobs of plural sheets for plural different recipients in plural print job storage mailbox bins, with at least most of said mailbox bins having a preset maximum sheet stacking capacity, said mailboxing system having a sheet distribution system controlled by a control system for automatically variably directing and stacking into different individual said mailbox bins the respective print jobs of different recipients, said control system providing for respective said mailbox bins to be electronically assignable to different respective recipients, and further including a bin stacking level indicator system for indicating to said control system that the number or height of the stack of sheets stacked in a said mailbox bin has reached a preset stacking level, the improvement comprising: a dual mode bin stacking level indicator system operatively connected to said control system to control said sheet distribution system for said bins, said control system providing a selection between the exclusive said assignment of only one recipient to one or more mailbox bins and the shared said assignment of plural recipients to one or more mailbox bins for receiving said print jobs to be stacked therein, and said dual mode bin stacking level indicator system having two different bin stacking level estimation systems, selectable by said control system, a first bin stacking level estimation system selected by said control system in accordance with said selection of said exclusive assignment of only one recipient to one or more mailbox bins, and a second bin stacking level estimation system selectable by said control system in accordance with said selection of said shared assignment of plural recipients to one or more mailbox bins.
Claim 2
Dependent Claim
285 words
In a shared users plural bins mailboxing system adapted to receive and stack plural print jobs of plural sheets for plural different recipients in plural print job storage mailbox bins, with at least most of said mailbox bins having a preset maximum sheet stacking capacity, said mailboxing system having a sheet distribution system controlled by a control system for automatically variably directing and stacking into different individual said mailbox bins the respective print jobs of different recipients, said control system providing for respective said mailbox bins to be electronically assignable to different respective recipients, and further including a bin stacking level indicator system for indicating to said control system that the number or height of the stack of sheets stacked in a said mailbox bin has reached a preset stacking level, the improvement comprising: a dual mode bin stacking level indicator system operatively connected to said control system to control said sheet distribution system for said bins, said control system providing a selection between the exclusive said assignment of only one recipient to one or more mailbox bins and the shared said assignment of plural recipients to one or more mailbox bins for receiving said print jobs to be stacked therein, and said dual mode bin stacking level indicator system having two different bin stacking level estimation systems, selectable by said control system, a first bin stacking level estimation system selected by said control system in accordance with said selection of said exclusive assignment of only one recipient to one or more mailbox bins, and a second bin stacking level estimation system selectable by said control system in accordance with said selection of said shared assignment of plural recipients to one or more mailbox bins.
Claim 3
Dependent Claim
93 words
The shared users plural bins mailboxing system of claim 1, further including a display operatively connecting with said control system, and wherein said control system provides an additional selection for said selection of said shared assignment of more than one recipients to one or more mailbox bins, said additional selection causing said display to display instructions to any of said plural recipients of print jobs in said shared bins to remove all of said print jobs in that said shared bin when said shared bin is accessed by any of said plural recipients.
Claim 4
Dependent Claim
73 words
The shared users plural bins mailboxing system of claim 1, wherein said mailboxing system comprises a shared array of multiple said mailbox bins, and said control system provides a selection as to selected individual mailbox bins between said exclusive assignment of only one recipient to selected mailbox bins and said shared assignment of plural recipients per bin to other selected mailbox bins of the same said shared array of multiple said mailbox bins.
Claim 5
Dependent Claim
63 words
The shared users plural bins mailboxing system of claim 1, wherein said dual mode bin stacking level indicator system includes a print jobs sheet counting system for counting the number of sheets to be directed by said sheet distribution system to a particular selected said mailbox bin for estimating the stack height of the stack of sheets in said particular selected mailbox bin.
Claim 6
Dependent Claim
86 words
The shared users plural bins mailboxing system of claim 1, wherein said dual mode bin stacking level indicator system comprises both a print jobs sheet counting system for counting the number of sheets to be directed by said sheet distribution system to a particular selected said mailbox bin to estimate the stack height of the stack of sheets in said particular selected mailbox bin, and a stack height sensor system for sensing the stack height of the stack of sheets in said particular selected mailbox bin.
Claim 7
Dependent Claim
41 words
The shared users plural bins mailboxing system of claim 1, wherein said dual mode bin stacking level indicator system includes a stack height sensor system for sensing the stack height of the stack of sheets in said particular selected mailbox bin.
Claim 8
Dependent Claim
80 words
The shared users plural bins mailboxing system of claim 5, wherein said control system controls said dual mode bin stacking level indicator system to utilize said counting system for those said mailbox bins which said control system has exclusively assigned to only one recipient, and said control system controls said dual mode bin stacking level indicator system to utilize said stack height sensor system for those said mailbox bins which said control system has assigned to plural recipients per bin.
Claim 9
Dependent Claim
71 words
The shared users plural bins mailboxing system of claim 6, wherein said mailboxing system comprises a shared array of multiple said mailbox bins, and wherein said stack height sensor system comprises a single sensor which is movable under the control of said control system between said multiple said mailbox bins of said array for said sensing of the stack height of the stack of sheets in said particular selected mailbox bin.
