Abstract

Embodiments described herein include a composite feeding mechanism configured to process one or more jobs using a stack of feeder trays. The composite feeding mechanism can include the stack of feeder trays, a base unit, and a feeder unit. The feeder trays can hold substrate media to satisfy jobs and the base unit can support the stack of feeder trays. The feeder unit can remove the substrate media from a feeder tray located at the top of the stack to satisfy a job requirement.

3. The composite feeding mechanism of claim 1, wherein one or more of the plurality of feeder trays are configured for a specific substrate media.

4. The composite feeding mechanism of claim 1, wherein one or more of the plurality of feeder trays can be adjusted to accommodate different substrate media.

5. The composite feeding mechanism of claim 1, wherein one of the plurality of feeder trays include one or more registering mechanisms that interface with the feeder unit to facilitate removal of substrate media from the first one of the plurality of feeder trays.

6. The composite feeding mechanism of claim 1, wherein one or more of the plurality of feeder trays includes an identifier, the identifier associated with information regarding at least one of the one or more of the plurality of feeder trays and contents of the one or more of the plurality of feeder trays.

7. The composite feeding mechanism of claim 6, wherein the identifier is associated with at least one a type of substrate media, a size of substrate media, an amount of substrate media, and a location of one or more of the plurality of feeder trays in the stack.

8. The composite feeding mechanism of claim 6, wherein the identifier comprises at least one of a bar code, a customer replaceable unit monitor (CRUM), and a radio frequency identification (RFID) tag.

9. The composite feeding mechanism of claim 1, wherein a first one of the plurality of feeder trays in the stack rests on a second one of the plurality of feeder trays in the stack so that the first one of the plurality of feeder trays is at least partially supported by the second of the plurality of feeder trays.

10. The composite feeding mechanism of claim 9, wherein the first one of the plurality of trays includes a pair of contoured side wall having a jog that forms a ridge and the ridge rests on top edges of side walls of the second one of the plurality of feeder trays.

11. A printing system comprising:

a composite feeding mechanism configured to process one or more print jobs using a stack of feeder trays, at least one of the feeder trays includes an identifier for identifying information regarding at least one print job to be satisfied by the at least one of the feeder trays, the identifier being at least one of a bar code, CRUM, and RFID tag, the composite feeding mechanism configured to adjust a vertical position of the stack so that a top one of the feeder trays is selected to satisfy the at least one print job and to separate the top one of the feeder trays from the stack from a remainder of the feeder trays in the stack after the at least one print job is satisfied, the composite feeding mechanism configured to discharge the top one of the feeder trays after the top one of the feeder trays is separated from the stack.

12. The printing system of claim 11, wherein the composite feeding mechanism comprises a feeder unit configured to remove substrate media from the top one of the feeder trays to satisfy the job.

13. The printing system of claim 11, wherein a first one of the plurality of feeder trays in the stack rests on a second one of the plurality of feeder trays in the stack so that the first one of the plurality of feeder trays is at least partially supported by the second of the plurality of feeder trays.

14. The printing system of claim 11, wherein the composite feeding mechanism comprises:

a tray separator configured to separate the top one of the feeder trays in the stack from a remainder of the feeder trays in the stack; and

a discharge path through which the top one of the feeder trays is discharged after the top one of the feeder trays is separated from the stack.

15. A method of satisfying print jobs in a printing system comprising:

adjusting a vertical position of a stack of feeder trays to facilitate removal of substrate media sheet-by-sheet from a top one of the feeder trays in the stack to satisfy one or more print jobs;

associating the top one of the feeder trays with at least one of the one or more print jobs based on an identifier disposed on the top one of the feeder trays;

removing the substrate media from the top one of the feeder trays sheet-by-sheet, the substrate media being used to generate printouts; and

removing the top one of the feeder trays from the stack after the job is satisfied to process a subsequent print job using a next one of the feeding trays in the stack.

16. The method of claim 15, wherein removing the top one of the feeder trays comprises:

separating the top one of the feeder trays from the stack using a tray separator; and

placing the top one of the feeder trays on a used tray holder.

17. The method of claim 15 further comprising:

determining whether the top one of the feeder trays is configured to satisfy the at least one or more jobs based on the association.

18. A composite feeding mechanism comprising:

a plurality of feeder trays for holding sheets substrate media, the plurality of feeder trays being stackable on each other so that adjacent feeding trays form a stack of feeder trays in contact with each other;

a base unit for supporting the stack of feeder trays; and

a feeder unit for removing the substrate media sheet-by-sheet from a first one of the plurality of feeder trays located at the top of the stack of feeder trays to satisfy a print job,

wherein one or more of the plurality of feeder trays includes an identifier, the identifier associated with information regarding at least one print job to be satisfied by at least one of the one or more of the plurality of feeder trays and content of the one or more of the plurality of feeder trays, and
