Zusammenfassung: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.
