Media size sensor assemblies

Abstract

Example media size sensor assemblies and media handling device including the example media size sensor assemblies are disclosed. In an example, the media size sensor assembly includes a sensor to be mounted within the media handling device, the sensor to detect reflected light. In addition, the media size sensor assembly includes a plurality of reflective surfaces to be coupled to a width adjustment wall of a storage tray of the media handling device, such that movement of the width adjustment wall is to align a selected one of the plurality of reflective surfaces with the sensor. The reflective surfaces of the plurality of reflective surfaces are to reflect different amounts of light.

   wherein the width adjustment wall is to move relative to the storage tray to align a selected one of the plurality of reflective surfaces with the sensor, and   wherein the reflective surfaces are to reflect different amounts of light.   
     
     
         2 . The media handling device of  claim 1 , wherein the media size sensor assembly comprises a controller coupled to the sensor, wherein the controller is to determine a position of the width adjustment wall based on an amount of reflected light detected by the sensor. 
     
     
         3 . The media handling device of  claim 1 , wherein a first of the plurality of reflective surfaces is coupled to the width adjustment wall on a first side of the storage tray, and wherein a second of the plurality of reflective surfaces is coupled to the width adjustment wall on a second side of the storage tray that is opposite the first side. 
     
     
         4 . The media handling device of  claim 3 , wherein the second of the plurality of reflective surfaces is pivotably coupled to the width adjustment wall. 
     
     
         5 . The media handling device of  claim 4 , wherein the second of the plurality of reflective surface is pivotably biased relative to the width adjustment wall. 
     
     
         6 . The media handling device of  claim 5 , wherein the first of the plurality of reflective surfaces is to reflect a first amount of light to the sensor, and wherein the second of the plurality of reflective surface is to reflect a second amount of light to the sensor that is greater than the first amount of light. 
     
     
         7 . A media size sensor assembly for a media handling device, the media size sensor assembly comprising:
 a sensor to be mounted within the media handling device, the sensor to detect reflected light; and   a plurality of reflective surfaces to be coupled to a width adjustment wall of a storage tray of the media handling device such that movement of the width adjustment wall is to align a selected one of the plurality of reflective surfaces with the sensor and wherein the reflective surfaces are to reflect different amounts of light.   
     
     
         8 . The media size sensor assembly of  claim 7 , comprising a controller coupled to the sensor, wherein the controller is to determine a position of the width adjustment wall based on an amount of reflected light detected by the sensor. 
     
     
         9 . The media size sensor assembly of  claim 8 , wherein a first of the plurality of reflective surfaces is to be coupled to the width adjustment wall on a first side of a the storage tray, and wherein a second of the plurality of reflective surfaces is coupled to the width adjustment wall on a second side of the storage tray that is opposite the first side. 
     
     
         10 . The media size sensor assembly of  claim 9 , wherein the second of the plurality of reflective surfaces is to be pivotably coupled to the width adjustment wall. 
     
     
         11 . The media size sensor assembly of  claim 10 , wherein the first of the plurality of reflective surfaces is to reflect a first amount of light to the sensor, and wherein the second of the plurality of reflective surface is to reflect a second amount of light to the sensor that is greater than the first amount of light. 
     
     
         12 . A media handling device comprising:
 a storage tray to store media;   a width adjustment wall coupled to the storage tray; and   a controller to:
 receive a signal from an optical sensor, the signal indicating an amount of reflected light; and 
 determine, based on the amount of reflected light, a position of the adjustment wall along the storage tray. 
   
     
     
         13 . The media handling device of  claim 12 , comprising a plurality of reflective surfaces coupled to the width adjustment wall, wherein the reflective surfaces are to reflect different amounts of light. 
     
     
         14 . The media handling device of  claim 13 , wherein a first reflective surface of the plurality of reflective surfaces is coupled to the width adjustment wall on a first side of the storage tray, and wherein a second reflective surface of the plurality of reflective surfaces is coupled to the width adjustment wall on a second side of the storage tray that is opposite the first side. 
     
     
         15 . The media handling device of  claim 14 , wherein the second reflective surface is pivotably coupled to the width and is pivotably biased relative to the width adjustment wall.
