Abstract

A media tray may include a lift plate to lift a number of sheets of media, a spool, and a first plurality of cables and a second plurality of cables each mechanically coupling the lift plate to the spool wherein the first and second plurality of cables cause the sheets of media to interface with a media pick-up roller at a horizontally divergent angle relative to a pick-up roller.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A media tray, comprising:
 a lift plate to lift a number of sheets of media;   a spool; and   a first plurality of cables and a second plurality of cables each mechanically coupling the lift plate to the spool;   wherein the first and second plurality of cables cause the sheets of media to interface with a media pick-up roller at a horizontally divergent angle relative to a pick-up roller.   
     
     
         2 . The media tray of  claim 1 , wherein the horizontally divergent angle is between 5 and 17 degrees angled down relative to the pick-up roller. 
     
     
         3 . The media tray of  claim 2 , wherein the length of the first plurality of cables causes a first side of the lift plate to obtain a position higher towards the pick-up roller relative to a second side of the lift plate. 
     
     
         4 . The media tray of  claim 3 , wherein the length of the second plurality of cables causes the second side of the lift plate to obtain a position lower from the pick-up roller relative to the first side of the lift plate. 
     
     
         5 . The media tray of  claim 1 , wherein a first side of the lift plate remains in a higher position than a second side of the lift plate while the spool winds up a length of both the first plurality of cables and the second plurality of cables. 
     
     
         6 . The media tray of  claim 1 , wherein the second plurality of cables interfaces with an accumulator device to maintain a slack amount of cable while the lift plate is located at a bottom-most portion of the media tray. 
     
     
         7 . A printing device, comprising:
 a number of media trays, each media tray comprising:
 a media plate to support a number of sheets of media; and 
 a winching system to winch at least a first set of two cables and a second set of two cables, the first and second set of cables coupled to the media plate; 
 wherein the winching system causes the media plate to be angled when the sheets of media interface with a pick-up roller. 
   
     
     
         8 . The printing device of  claim 7 , wherein the media tray is removable from the printing system. 
     
     
         9 . The printing device of  claim 7 , wherein each of the winching system comprises a spool to wind-up the first and second set of cables. 
     
     
         10 . The printing device of  claim 9 , wherein the spool comprises a coupler to interface with a drive motor of the printing device. 
     
     
         11 . The printing device of  claim 9 , further comprising an accumulation mechanism to accumulate a slack amount of cable of the second set of two cables. 
     
     
         12 . The printing device of  claim 7 , wherein the angle of the media plate is between 5 and 17 degrees angled down relative to the pick-up roller. 
     
     
         13 . A media supply device, comprising:
 a lift plate to hold an amount of media;   a winch system comprising a motor and a spool; and   at least a first cable and a second cable each coupled at a first end to the lift plate and at a second end to the spool;   wherein rotation of the spool causes a first cable to lift a first side of the lift plate while an amount of slack of the second cable is wound around the spool before lifting a second end of the lift plate.   
     
     
         14 . The media supply device of  claim 13 , wherein a portion of the spool where the at least first cable and second cable are wound around have a common diameter. 
     
     
         15 . The media supply device of  claim 13 , further comprising an accumulation device to accumulate the slack of the second cable when present.
