Abstract
A dual bin paper feed tray is removably insertable into the standard height tray-receiving housing opening of an image reproduction machine such as a printer or copier. The tray has adjacent front and rear paper holding bin areas each configured to hold a stack of approximately 250 cut paper sheets, the overall tray thus being adapted to hold the entire contents of a standard one ream package of cut paper sheets. In operation, the loaded tray is inserted, front end first, into the housing opening and the machine's paper feed system operates to sequentially feed paper sheets from the front tray bin into the machine. When the machine's paper sensing system detects that the front bin has been emptied, a shift structure incorporating a motor-driven gear train and associated cam/follower apparatus is automatically operated to move the rear paper stack into the front tray bin for infeed to the machine.
