Abstract

An electrophotographic device includes a scanning unit, at least one media output option for receiving a media sheet, and at least one light source for emitting a light beam to at least partially illuminate a media sheet receiving portion of the at least one media output tray. The media output tray is vertically stacked below the scanning unit. Still further, a user alert display is provided to alert a user to the presence of a media sheet in the output tray. A sensor detects a media sheet received in the output tray, and activates the light source and optionally the user alert display. The media output option may include a plurality of output trays, each output tray having a dedicated light source, user alert display, and sensor.

Claims (19)

1. An electrophotographic device for transferring an image to at least one media sheet, comprising;

at least one media output option for receiving an imaged media sheet;

at least one light source for emitting a light beam to at least partially illuminate a media sheet receiving portion of the at least one media output option; and

at least one sensor for sensing at least one media sheet received in the at least one media output option, wherein the at least one sensor senses the at least one media sheet and activates the at least one light source;

wherein a first portion of the emitted light beam is directed in a first direction to at least partially illuminate the media sheet receiving portion of the at least one media output option, and a second portion of the emitted light beam is directed in a second direction different from the first direction to provide at least one user alert display for alerting a user to the presence of the at least one media sheet received in the at least one media output option.

2. The device of claim 1 , wherein the at least one media output option includes a plurality of output trays, the at least one light source includes a plurality of light sources, each light source corresponding to a distinct output tray and emitting a light beam in a first direction to at least partly illuminate a media sheet receiving portion of a corresponding output tray and in a second direction to provide a distinct user alert display.

3. The device of claim 2 , wherein the at least one sensor comprises a plurality of sensors, each sensor corresponding to a distinct output tray for sensing at least one media sheet received in a media sheet receiving portion thereof and activating the light source corresponding to the output tray.

4. An electrophotographic device for transferring an image to at least one media sheet, comprising:

a scanning unit;

at least one media output option including a plurality of output trays for receiving at least one imaged media sheet, wherein the media output option is vertically stacked below the scanning unit;

a plurality of light sources, each light source for emitting a light beam to at least partially illuminate a media sheet receiving portion of a distinct output tray, each output tray corresponding to a distinct light source; and

a plurality of sensors, each sensor corresponding to an output tray for sensing at least one media sheet received therein, wherein each sensor senses the at least one media sheet and activates the corresponding light source;

wherein a first portion of each emitted light beam is directed in a first direction to at least partially illuminate the media sheet receiving portion of a corresponding output tray, and in a second direction, different from the first direction, to provide a user alert display for the corresponding output tray, alerting a user to the presence of at least one imaged media sheet received therein.

5. In an electrophotographic device for transferring an image to at least one media sheet, a method for alerting a user to delivery of a media sheet to a media output option, comprising:

sensing delivery of at least one media sheet to at least one media output option by at least one sensor;

activating at least one light source to emit a light beam in response to sensing delivery of the at least one media sheet; and

directing a first portion of the emitted light beam in a first direction to at least partially illuminate a media sheet receiving portion of the at least one media output option, and directing a second portion of the emitted light beam in a second, different direction to provide at least one user alert display for alerting a user to the presence of the at least one media sheet received in the at least one media output option.

6. The method of claim 5 , including providing at least one media output option having a plurality of output trays.

7. The method of claim 5 , wherein the at least one light source includes a plurality of light sources, the at least one media output option comprises a plurality of output trays, each output tray corresponding to a distinct light source, the sensing comprises sensing delivery of the at least one media sheet to each of the output trays, the at least one user alert display comprises a plurality thereof, each user alert display corresponding to a distinct output tray, and the directing comprises directing an emitted light beam from each light source in the first direction to at least partially illuminate the media receiving portion of a corresponding output tray and in the second direction to provide the user alert display corresponding to the output tray.
