Abstract

In one example, a media size detector includes a button coupled to a spring of a housing to interact with a media size adjuster of a media tray, a first side of a lever to receive pressure from the spring when the button is depressed by the media size adjuster, and a second side of the lever to apply pressure to activate or deactivate a switch coupled to a printed circuit assembly when the first side of the lever receives pressure from the spring.

First claim

What is claimed:

1. A media size detector, comprising:
a button coupled to a spring of a housing to interact with a media size adjuster of a media tray;
a size detect barrel, positioned between the button and the media tray, coupled to the media size adjuster to rotate based on a position of the media size adjuster, wherein the size detect barrel includes a barrel surface to interact with the button from a plurality of barrel surfaces that protrude from the size detect barrel;
a first side of a lever to receive pressure from the spring when the button is depressed by the media size adjuster; and
a second side of the lever to apply pressure to activate or deactivate a switch coupled to a printed circuit assembly when the first side of the lever receives pressure from the spring.

2. The media size detector of claim 1 , wherein a signal is sent by the printed circuit assembly to a computing device of a printing device based on whether the switch is activated or deactivated.

3. The media size detector of claim 1 , wherein the size detect barrel is positioned between a top portion and a bottom portion of the media tray.

4. The media size detector of claim 1 , wherein the first side of the lever is on a first side of the printed circuit assembly and the switch is on a second side of the printed circuit assembly.

5. The media size detector of claim 1 , wherein the button interacts with the media size adjuster in a first direction and the second side of the lever applies pressure to the switch in a second direction that is perpendicular to the first direction.

6. A system for media size detection, comprising:
a media size adjuster coupled within a media tray to rotate a size detect barrel based on a selected size of print media;
a media size detector coupled to a rail of the media tray to interact with the size detect barrel, wherein the size detect barrel depresses a combination of buttons of the media size detector based on an orientation of the size detect barrel; and
a printed circuit assembly to generate a signal based on the combination of buttons depressed by the size detect barrel, wherein the size detect barrel is positioned between the buttons of the media size detector and the media tray and wherein the size detect barrel includes barrel surfaces to depress the combination of buttons based on a rotation of the size detect barrel.

7. The system of claim 6 , wherein the signal corresponds to a particular media size selected by the media size adjuster.

8. The system of claim 7 , wherein the particular media size within the media tray is determined based on the generated signal.

9. The system of claim 6 , wherein the size detect barrel is coupled to the media tray and rotates the orientation based on adjustments of the media size adjuster.

10. The system of claim 6 , wherein the size detect barrel interacts with a plurality of buttons when the media tray is in a closed position.

11. A system for media size detector, comprising:
a plurality of buttons coupled to a first side of a printed circuit assembly to interact with a plurality of barrel surfaces based on an orientation of a size detect barrel positioned between the plurality of buttons of the media size detector and a media tray, wherein a portion of the plurality of barrel surfaces depress a corresponding portion of the plurality of buttons based on the orientation; and
a plurality of levers to receive pressure from the corresponding portion of the plurality of buttons on a first side and interact with a corresponding switch coupled to a second side of the printed circuit assembly with a second side.

12. The system of claim 11 , wherein the plurality of buttons are coupled to a corresponding plunger to interact with a spring positioned within a housing.

13. The system of claim 12 , wherein the plurality of buttons extend outside the housing and the plunger is positioned inside the housing.

14. The system of claim 12 , wherein the housing is coupled to a rail of a media tray utilizing the media size adjuster and the size detect barrel is coupled to the media tray.

15. The system of claim 11 , wherein the printed circuit assembly alters a voltage based on the corresponding portion of the plurality of buttons depressed by the barrel surfaces of the size detect barrel.
