摘要： In a copier, printer, or similar device, paper is loaded in large quantities. To separate a top sheet of a stack of sheets from the next adjacent sheet, a dam is used, which is an element having an inclined surface in the path of the top sheet. This invention addresses devices with variably compliant separation strips, preferably a thermoplastic polyurethane elastomer such as Pellethane®, that are part of the dam, so that the leading edge of a media sheet will strike the inclined surface of the separation strip. By adjusting the compliance of the separation strip, different weights of media may be accommodated while minimizing the multi-feeds that may cause jamming of the device.

摘要： A reusable media shell has a frame to hold sheets of media in an interior. A removable cap connects to the frame and its manipulation unveils the media for picking by an imaging device. The cap resides on a terminal end of the frame so the frame covers a majority of the media. A lift plate in the interior forces upward the sheets for picking. Two magnets on the frame magnetically secure the frame to magnets in a base of the imaging device and position the sheets in the base. Upstanding walls, a lid and bottom define the interior of the frame. Inserts attached to the walls allow adjustment to accommodate various sizes of the media.
