Abstract

A device for moving a sheet of media in a device or machine for handling stacks of media is provided. The device includes a roll, an arm, and a bias element. The roll may be in contact with the sheet of media. The arm may be coupled to the roll. The bias element has a first end and a second end. Either the first end of the bias element is adjustably coupled to the arm or the second end of the bias element is adjustably coupled to the body. The body supports the bias element. The first end of the bias element may be coupled to the arm and the second end may be capable of adjustably coupling with the body in at least two positions (e.g., two or more of a nominal load setting, a reduced load setting, and an increased load setting).

1 . A device for moving a sheet of media in a machine, comprising:
 a roll capable of contacting the sheet of media;   an arm coupled to the roll;   a bias element having a first end and a second end, the first end of the bias element being adjustably coupled to the arm and/or the second end of the bias element being adjustably coupled to the body; and   a body supporting the bias element.   
   
   
       2 . The device of  claim 1 , wherein the first end of the bias element is coupled to the arm and the second end is capable of adjustably coupling with the body in at least two positions. 
   
   
       3 . The device of  claim 2 , wherein the at least two positions are two or more of a nominal load setting, a reduced load setting, and an increased load setting. 
   
   
       4 . The device of  claim 1 , wherein the first end is adjustably coupled with the arm in one of at least two positions and the second end is fixed to the body. 
   
   
       5 . The device of  claim 4 , wherein the at least two positions are two or more of a nominal load setting, a reduced load setting, and an increased load setting. 
   
   
       6 . The device of  claim 1 , wherein the body has castellations and the second end of the bias element is adjustably coupled to the body at one of the castellations. 
   
   
       7 . The device of  claim 1 , wherein the body has detent features and the second end of the bias element is adjustably coupled to the body at one of the detent features. 
   
   
       8 . The device of  claim 1 , wherein the body has a removable component for preventing adjustment of the coupling of the second end of the bias element. 
   
   
       9 . The device of  claim 8 , wherein the component is removed from the body. 
   
   
       10 . The device of  claim 9 , further comprising:
 a retainer to retain the removed component in the machine.   
   
   
       11 . The device of  claim 1 , further comprising:
 a drive shaft;   a motor coupled to the drive shaft; and   a drive belt coupled to the drive shaft and the arm of the device.   
   
   
       12 . A method of manufacturing a device for moving a sheet of media in a machine, comprising:
 providing a roll;   coupling an arm to the roll;   providing a body;   adjustably coupling a bias element to the body and/or arm.   
   
   
       13 . The method of  claim 12 , the bias element having a first and a second end, the method further comprising:
 adjustably coupling the first end of the bias element to the arm or adjustably coupling the second end of the bias element with the body in one of at least two positions.   
   
   
       14 . The method of  claim 13 , wherein the at least two positions are two or more of a nominal load setting, a reduced load setting, and an increased load setting. 
   
   
       15 . The method of  claim 13 , further comprising:
 adjustably coupling the first end with the arm in one of at least two positions; and   fixing the second end to the body.   
   
   
       16 . The method of  claim 15 , wherein the at least two positions are two or more of a nominal load setting, a reduced load setting, and an increased load setting. 
   
   
       17 . The method of  claim 13 , the body having castellations, the method further comprising:
 coupling the second end of the bias element to one of the castellations.   
   
   
       18 . The method of  claim 13 , the body having detent features, the method further comprising:
 coupling to the second end of the bias element to one of the detent features.   
   
   
       19 . The method of  claim 13 , the body having a removable component, the method further comprising:
 preventing adjustment in the coupling of the second end of the bias element with the removable component.   
   
   
       20 . A method for moving a sheet of media in a device, comprising:
 applying pressure to the media to move the media;   adjusting the pressure to the media based on predetermined media parameters; and   optionally adjusting the pressure to the media based on operating parameters of the device.
