Preventing media misalignment during accumulation

Abstract

In one example in accordance with the present disclosure a system for preventing media misalignment during accumulation. The system includes a number of media clamps having multiple positions to prevent misalignment of an incoming media sheet during accumulation. The number of media clamps are in a raised position after a leading edge of the incoming media sheet has passed over a trailing edge of the stack region. The media clamps are in a clamped position after the leading edge of the incoming media sheet has passed the media clamp.

What is claimed is: 
     
         1 . A system for preventing media misalignment during accumulation, the system comprising:
 a number of media clamps having multiple positions to prevent misalignment of an incoming media sheet during accumulation, wherein the number of media clamps:
 are in a raised position after a leading edge of the incoming media sheet has passed over a trailing edge of the stack region; and 
 are in a clamped position after the leading edge of the incoming media sheet has passed the number of media clamps. 
   
     
     
         2 . The system of  claim 1 , wherein the number of media clamps are proximate the trailing edge of the stack region. 
     
     
         3 . The system of  claim 1 , wherein the number of media clamps form a set selected from a number of sets of media claims, each set pertaining to a different media size. 
     
     
         4 . The system of  claim 1 , wherein:
 a raised position comprises an intermediate position and a high position;   the number of media clamps are in the high position after the leading edge of the incoming media sheet has passed over the trailing edge of the stack region; and   the number of media clamps are in the intermediate position during an x-direction alignment of the incoming media sheet.   
     
     
         5 . The system of  claim 4 , wherein the number of media clamps are in the intermediate position for a portion of a y-direction alignment of the incoming media sheet. 
     
     
         6 . The system of  claim 1 , wherein the number of media clamps are in a clamped position until a leading edge of the incoming media sheet has passed over the trailing edge of the stack region. 
     
     
         7 . A method for preventing misalignment of an incoming media sheet, the method comprising:
 placing media clamps having multiple positions in a clamped position until a leading edge of the incoming media sheet has passed over a trailing edge of a stack region;   raising the media clamps after the leading edge of the incoming media sheet has passed over the trailing edge of the stack region; and   lowering the media clamps to align the incoming media sheet with the stack region after the leading edge of the incoming media sheet has passed the media clamp.   
     
     
         8 . The method of  claim 7 , further comprising:
 lowering the media clamps to an intermediate position during an x-direction alignment of the incoming media sheet; and   lowering the media clamps to a clamped position for at least a portion of a y-direction alignment of the incoming media sheet.   
     
     
         9 . The method of  claim 7 , wherein raising the media clamps comprises raising the media clamps to a high position after the leading edge of the incoming media sheet has passed over the trailing edge of the stack region. 
     
     
         10 . The method of  claim 7 , further comprising receiving at least a partially-dry incoming media sheet. 
     
     
         11 . The method of  claim 7 , further comprising calibrating an intermediate height of a set of media clamps relative to a media support device by:
 lowering the media clamps to an elevation lower than the media support device;   translating the media support device towards the media clamps;   detecting contact between the media support device and the media clamps;   incrementally raising the media clamp and translating the media support device towards the media clamps until no contact is detected between the media support device and the media clamps; and   once no contact is detected between the media support device and the media clamps, raising the media clamps a predetermined distance.   
     
     
         12 . A system for preventing misalignment of an incoming media sheet, the system comprising:
 a number of sets of media clamps having multiple positions, each set of media clamps corresponding to a different media size, each set to:
 manage alignment of an incoming media sheet when the incoming media sheet is of a corresponding media size, wherein when managing alignment of an incoming media sheet, a set of media clamps:
 are in a clamped position until a leading edge of the incoming media sheet has passed over a stack region of a media support device; 
 are in a raised position after the leading edge of the incoming media sheet has passed over a trailing edge of the stack region; and 
 return to the clamped position to maintain an alignment of the incoming media sheet relative to the stack region; and 
 
 be in a raised position when an incoming media sheet is not of a corresponding media size. 
   
     
     
         13 . The system of  claim 12 , wherein a set of media clamps are aligned with the stack region of a corresponding media size. 
     
     
         14 . The system of  claim 12 , wherein motion of media clamps within a set is independently controlled to allow equal contact of the media clamps within the set on at least one of a media stack and media support assembly. 
     
     
         15 . The system of  claim 12 , wherein at least one set of media clamps is actuated by motion of a media transport assembly.
