of both clutches 182, 184.
Media 114 exiting exit nip 160N is retained in output area 118. For duplexing, a second media path 142 (return path) is provided beginning at an intersection 144 with first media path 140 near exit roll assembly 160 and ending adjacent the start of media path 140 at an intersection 146 with first media path 140. The diverter structure, gate 150, is positioned at intersection 144 and is used to divert a media sheet being retracted by exit roll assembly 160 into second media path 142. First media path 140 begins adjacent pick roll 112 and extends to exit assembly 160, passing through feed roll assemblies 120, 130 and processing zone A and continues to intersection 144. First and second media paths 140 andof exit roll assembly 160 and pick assembly 110, respectively, while media sheets are being scanned, in order to achieve consistent media velocity during a scanning operation.
For media processing, exemplified by ADF 100, the drive and idler rolls 160D, 160N are typically designed to have a low nip force in order to allow the feed roll assembly 130 to overcome the nip force at drive and idler rolls 160D, 160N and provide a smooth motion of the media sheets at the image processing zone A, even when exit roll assembly 160 is driving a media sheets towards the output location 118. Alternatively, the height of nip 160N may be increased to avoid any interference during an image processing operation such as scanning or printing of the media sheets.
