Abstract

The present disclosure discloses a moveable feeder assembly/unit for multi-function devices and corresponding retrieval and printing methods. Here, a multi-function device is disclosed. The multi-function device includes multiple trays. Each tray is configured to receive or store one or more media sheets, and further is positioned at a respective vertical height. The multi-function device further includes a single moveable feeder unit for all trays at the multi-function device. The single moveable feeder unit is configured to move across a plurality of positions to reposition itself proximate to a target tray of multiple trays, selected for printing operation.

First claim

What is claimed is:

1. A multi-function device, comprising:
a plurality of trays, wherein each of the plurality of trays is configured to store a media sheet stack, and wherein each of the plurality of trays is to be positioned at a respective vertical height;
a single moveable feeder unit, comprising:
the plurality of trays, configured to move from a current position to a position proximate a target tray for retrieving one or more media sheets from the target tray; and
a blade for cutting a jammed media sheet during a jamming situation;

a controller; and
a memory configured to store a plurality of instructions, wherein the plurality of instructions, upon execution by the controller, cause the controller to:
receive a request for printing a document, wherein the request comprising at least: a media size, a media type, and a tray,
identify the target tray of the plurality of trays, to be used for printing the document, based on the request,
move the single moveable feeder unit from the current position to the position proximate the target tray for retrieving one or more media sheets from the target tray, and
print the document using the one or more retrieved media sheets present in the target tray, resulting print output.

2. The multi-function device of claim 1 , wherein the controller is to receive the current position of the single moveable feeder unit.

3. The multi-function device of claim 1 , wherein the single moveable feeder unit is configured to move across the plurality of trays at the multi-function device.

4. The multi-function device of claim 1 , wherein the single moveable feeder unit comprises a sensor for sensing at least: the current position of the single moveable feeder unit and a movement of the single moveable feeder unit.

5. The multi-function device of claim 1 , wherein the single moveable feeder unit comprises a print engine in communication with the single moveable feeder unit for receiving the one or more retrieved media sheets for printing content of the document.

6. The multi-function device of claim 1 , wherein the single moveable feeder unit comprises at least a folding feeder roller, one or more shafts, a drive mechanism, one or more motors, and one or more guides.

7. The multi-function device of claim 1 , wherein, upon retrieving the one or more media sheets from the target tray, the single moveable feeder unit is to return to a pre-defined position proximate to a pre-defined tray of the plurality of trays.

8. A multi-function device, comprising:
a plurality of trays, wherein each of the plurality of trays is configured to store a media sheet stack, and wherein each of the plurality of trays is to be positioned at a respective vertical height;
a single moveable feeder unit for the plurality of trays, configured to move from a current position to a position proximate a target tray for retrieving one or more media sheets from the target tray, and wherein the single moveable feeder unit comprises a blade for cutting a jammed media sheet during a jamming situation;
a controller; and
a memory configured to store a plurality of instructions, wherein the plurality of instructions, upon execution by the controller, cause the controller to:
receive a request for printing a document, wherein the request comprising at least: a media size, a media type, and a tray,
identify the target tray of the plurality of trays, to be used for printing the document, based on the request,
move the single moveable feeder unit from the current position to the position proximate the target tray for retrieving one or more media sheets from the target tray, and
print the document using the one or more retrieved media sheets present in the target tray, resulting print output.

9. The multi-function device of claim 8 , wherein the controller is to receive the current position of the single moveable feeder unit.

10. The multi-function device of claim 8 , wherein the single moveable feeder unit is configured to move across the plurality of trays at the multi-function device.

11. The multi-function device of claim 8 , wherein the single moveable feeder unit comprises a sensor for sensing at least: the current position of the single moveable feeder unit and a movement of the single moveable feeder unit.

12. The multi-function device of claim 8 , wherein the single moveable feeder unit comprises a print engine in communication with the single moveable feeder unit for receiving the one or more retrieved media sheets for printing content of the document.

13. The multi-function device of claim 8 , wherein the single moveable feeder unit comprises at least a folding feeder roller, one or more shafts, a drive mechanism, one or more motors, and one or more guides.

14. The multi-function device of claim 8 , wherein, upon retrieving the one or more media sheets from the target tray, the single moveable feeder unit is to return to a pre-defined position proximate to a pre-defined tray of the plurality of trays.
