Abstract:
1. A multiple media item feed system comprising: a media item tray for holding a plurality of media items; an adjustable prefeed roller adapted to engage and feed a selectable number of media items from said media item tray to form a group of overlapped media items when a stack of media items are loaded into said media item tray, wherein the prefeed roller is selectively positioned to improve the performance of the system for a length of the stack of media items and a force exerted by the prefeed roller on the media items is adjusted for the media items' coefficients of friction; a thickness sensor positioned to measure a thickness of media fed from said tray by said prefeed roller; and, an arming drive roller positioned downstream of said prefeed roller and to engage media items fed from said tray, said arming drive roller controllable to feed said group of media items when said thickness sensor has measured a proper thickness of media items present at said arming drive roller for said group of media items.
