Abstract

A drawer defines a chamber to receive a media sheet from a system. A moving element is to engage the media sheet as the media sheet is output from the system. The moving element is to slide the media sheet to a target position in the drawer, and the moving element is to disengage from the media sheet once the particular media sheet has reached the target position. A retaining element is to engage the media sheet as the media sheet slides into the drawer.

First claim

What is claimed is:

1. A media stacker comprising:
a drawer defining a chamber to receive media sheets from a system;
a moving element to engage a particular media sheet as the particular media sheet is output from the system, the moving element to slide the particular media sheet to a target position in the drawer, and the moving element to disengage from the particular media sheet once the particular media sheet has reached the target position; and
a retaining element to engage the particular media sheet as the particular media sheet slides into the drawer, wherein the retaining element includes a first roller, and the moving element includes a second roller, and wherein the first roller is an idle roller, and the second roller is a driven roller.

2. The media stacker of claim 1 , having a size to fit within a footprint of the system.

3. The media stacker of claim 1 , wherein the second roller is a D-shape roller.

4. The media stacker of claim 1 , wherein the drawer has a stop to engage the particular media sheet at the target position.

5. A media stacker comprising:
a drawer defining a chamber to receive media sheets from a system;
a moving element to engage a particular media sheet as the particular media sheet is output from the system, the moving element to slide the particular media sheet to a target position in the drawer, and the moving element to disengage from the particular media sheet once the particular media sheet has reached the target position;
a retaining element to engage the particular media sheet as the particular media sheet slides into the drawer; and
a support tray having at least a portion in the drawer, wherein the support tray is biased towards the retaining element and the moving element, and the support tray is to support the media sheets.

6. The media stacker of claim 5 , wherein the drawer includes springs to bias the support tray towards the retaining element and the moving element.

7. A printer system comprising:
a printer having an output port through which a printed media sheet is output, wherein the printer has a footprint; and
a media stacker attached to the printer, wherein the media stacker is arranged to fit within the footprint of the printer, and the media stacker comprises:
a drawer defining an inner chamber to receive the printed media sheet output by the printer;
a moving element to engage the printed media sheet as the printed media sheet is output from the printer, the moving element to slide the printed media sheet to a target position in the drawer, and the moving element to disengage from the printed media sheet once the printed media sheet has reached the target position; and
a retaining element to engage the printed media sheet as the printed media sheet slides into the drawer.

8. The printer system of claim 7 , wherein the media stacker has plural sets of the moving element and the retaining element to handle media sheets of different sizes.

9. The printer system of claim 7 , wherein the media stacker has a support tray having a portion extending into the drawer, the support tray to support the printed media sheet and other media sheets.

10. The printer system of claim 7 , wherein the moving element includes a D-shape roller.

11. The printer system of claim 10 , wherein the D-shape roller has a circular portion to engage the printed media sheet, and a non-circular portion to cause the D-shape roller to be disengaged from the printed media sheet once the printed media sheet has reached the target position.

12. The printer system of claim 10 , wherein the retaining element includes an idle roller.

13. A method comprising:
providing a drawer in a media stacker that defines a chamber to receive media sheets from a system;
arranging a moving element in the media stacker, where the moving element engages a particular media sheet as the particular media sheet is output from the system and received in the media stacker, the moving element to slide the particular media sheet to a target position in the drawer, and the moving element to disengage from the particular media sheet once the particular media sheet has reached the target position; and
arranging a retaining element in the media stacker to engage the particular media sheet as the particular media sheet is guided into the drawer,
wherein the media stacker has a size to fit within a footprint of the system, wherein the footprint of the system is an area projected onto a ground surface occupied by the system, and wherein the size of the media stacker does not extend beyond the footprint once the media stacker is attached to the system.

14. The method of claim 13 , further comprising providing a support tray having at least a portion in the drawer, wherein the support tray is biased towards the retaining element and the moving element, and the support tray is to support the media sheets.
