With reference to
The interposer 2 includes multiple interposer modules 12, 14, 16 and 18. Interposer module 12 includes an interposer module print media input 22 and corresponding interposer module print media input stack 30. Inter poser module 14 includes an interposer module print media input 24 and corresponding interposer module print media input stack 32. Interposer module 16 includes an interposer module print media input 26 and corresponding interposer module print media input stack 34. Interposer module 18 includes an interposer module print media input 28 and corresponding interposer module print media input stack 36. The fourth interposer 18 output is operatively connected to the input of an interface/purge module 20 which includes a print media output path operatively connected to the post print media handling system 10, and a print media purge path 33 which routes purged print media to a purge output stack 38.
With continuing reference to
In operation, the printing system illustrated in
Subsequently, the controller 4 communicates the first printing system print job to the first printing system, and communicates the second printing system print job to the second printing system. The printing systems print their respective sheets and output the printed sheets to a sheet stacking output. After completion of their respective print jobs, the first and second printing systems communicate to the controller 4 and/or the print media stack transport system 8, the completion of the print jobs.
At this point, the print media stack transport system 8 transports the first printing system output stack to the interposer 2, or more specifically an interposer module print media input, such as interposer module print media input 22, 24, 26 or 28. Furthermore, the print media stack transport system 8 transports the second printing system output stack to the interposer 2, or more specifically an interposer module print media input such as interposer module print media input 22, 24, 26 or 28. However, the first and second printing system output stacks are transported to different interposer module print media inputs for further processing by the interposer system 2.
For purposes of illustrating the operation of the interposer system 2 from this point, assume the output stack of the first printing system is transported to the first interposer module print media input 22, thereby positioning the first printing system output stack as the first interposer module print media input stack 30. Furthermore, assume the output stack of the second printing system is transported to the second interposer module print media input 24, thereby positioning the second printing system output stack as the second interposer module print media input stack 32. With the printing system output stacks positioned, as discussed above, printed sheets 1-50 of the original print job are located within the first interposer module 12 and printed sheets 51-100 of the original print job are located within the second interposer module 14.
To assemble or compile the printed sheets, the interposer system sequentially processes the first interposer print media input stack by routing these printed sheets via interposer module print media paths 23, 25, 27 and 29. The printed media sheets are subsequently routed to the post print media handling system 10 via the interface/purge module print media output 31. Subsequent to the sequential processing of printed sheets 1-50, printed sheets 51-100 are sequentially routed via interposer module print media paths 25, 27 and 29. Printed sheets 51-100 are then routed to the post print media handling system 10 via the interface/purge module print media output 31.
At this point, the original print job is completed, provided any post handling of the printed sheets is finished.
The printing system illustrated in
Other variations and modifications of the printing system described heretofore are described below.

Another exemplary embodiment of the printing system illustrated in
With reference to
The interposer system 40 includes a first interposer module 52, a second interposer module 54, a third interposer module 56, a fourth interposer module 58, an interface/purge module 60 and an interposer print media output stacker 62.
The first printing system includes a printing system sheet feeder 66, a printing module 68 for image marking, an output stacker 70 and a GUI 72.
The second printing system includes a printing system sheet feeder 74, a printing module 76 for image marking, an output stacker 78 and a GUI 80.
The third printing system includes a printing system sheet feeder 82, a printing module 84 for image marking, an output stacker 86 and a GUI 88.
The print media stack transport system 50 includes a stack transport command output 89, a first print media stack cart 90, a second print media stack cart 92 and a third media stack cart 94.
With continuing reference to
Print media flow 102, 104, 106 and 108 represent print media flow via the print media stack transport system 50 to interposer modules 52, 54, 56 and 58, respectively. Print media flow 110 represents the optional print media flow from the interposer print media output stacker 62 via the print media stack transport system 50.
In operation, the printing system illustrated in
The printing systems complete their assigned/communicated print jobs and produce print stacks at their respective output stackers 70, 78 and 86.
The print media stack transport system transports the printing system output stacks from the output stackers 70, 78 and 86 to the appropriate interposer modules 52, 54, 56, and 58.
From this point, the interposer system 40 assembles the document print job in the appropriate sheet sequence and ejects any unnecessary sheets, such as a traveler sheet, via the interface/purge module. The assembled document print job is outputted from the interposer system 40 via the interposer print media output stacker 62.
The assembled document print job can be optionally transported via the print media stack transport system 50 to a subsequent operation, for example, a finishing module or storage area, or another means of transporting the assembled document print job can be provided.
With reference to
In addition, a print media finishing module 122 is integrated with the interposer system 120.
The operation of the printing system illustrated in
The print media stack buffer 136 provides an area to store print media output stacks from one or more of printing systems 126, 128, 130 and 132, until the interposer system 120 has completed any previous document print jobs and/or is put into service. Furthermore, the print media stack buffer 136 provides a staging area for storing one or more print media stacks until all print media stacks required for assembly by the interposer system 120, are completed by the printing systems 126, 128, 130 and 132.
With reference to
Initially, the document print Job A 150 is divided and assigned to one or more printing systems which produce stack a 152, stack b 154, and stack c 156. Subsequently, stack a 152 is assigned 158 to a first stack input of the interposer system, stack b 154 is assigned 160 to a third stack input of the interposer system, and stack c 156 is assigned 162 to a second input of the interposer system. As illustrated in
Subsequent to the loading of stack a, stack b and stack c, the interposer system merges sheets from the interposer stack inputs to assemble print Job A.
With reference to
In operation, the scheduling software initially creates 170 one or more stacks for interposition to create a document Job A.
Next, the stacks are loaded 172 into interposer inputs.
Next, the scheduling software locates and acknowledges 174 all stacks for Job A are present.
Next, the scheduling software receives acknowledgement 176 that the finishing device is ready for Job A.

At this point, printing system 1 prints 196 its assigned sheets, printing system 2 prints 198 its assigned sheets and printing system 3 prints 200 its assigned sheets.
Next, printing system 1 compiles 202 its sheets into a stack, printing system 2 compiles 204 its sheets into a stack, and printing system 3 compiles 206 its sheets into a stack.
At this point, the stacks are transported 208 to the interposer system.
Next, the stacks are loaded 210 into interposer trays.
Next, the scheduling software locates and acknowledges 212 all stacks for Job A are present.
Next, the scheduling software receives 214 acknowledgement that the finishing device is ready for Job A.
Next, the scheduling software references the job structure and sends 216 feed commands to each interposer tray to reassemble the document job in correct sequence.
