Abstract

A media detection assembly for sensing media presence in a manual input feeder having a media support surface that is foldable out of a front of a removable media input tray of an image forming device. The media detection assembly includes a sensor disposed above the media support surface. A rotatable first arm is mounted above the media support surface and movable between a first position when no media is present in the media support surface and a second position when media is present in the media support surface. A rotatable second arm is mounted between the first arm and the sensor and is operatively connected to the first arm such that the second arm is movable by the first arm to change a state of the sensor when the first arm moves between the first position and the second position.

19. A removable media input tray for an image forming device, comprising:

a manual input feeder having a fold-out tray that is foldable out of a front of the media input tray for holding at least one media sheet;

a first arm pivotably mounted on the manual input feeder and movable between a first position when no media sheet is present in the fold-out tray and a second position when the at least one media sheet is disposed in the fold-out tray; and

a second arm pivotably mounted about a second pivot axis above the fold-out tray, the second arm is operatively connected to the first arm such that the second arm changes a state of a sensor in the image forming device when the first arm moves between the first position and the second position, wherein when the media input tray is removed from the image forming device, the first and second arms are separated from the sensor such that movement of the first and second arms does not change the state of the sensor.
