Abstract

A dual buffer internal to an imaging device uses a one-way, over-running clutch system to buffer multiple sheets of media between an internal drum recorder and a processor. The one-way over-running clutch system is incorporated into a drive system of a plurality of rollers that transport the media. An input set of rollers and an output set of rollers are driven independently to allow for two sheets of media to be buffered simultaneously and at different speeds if desired. The buffer is mounted pivotally within the imaging device to allow access into the imaging device and to allow installation of a take-up cassette as an alternative to the buffer.
