A conventional imagesetting system includes an imagesetter for transferring an image onto media, a wet chemical processor for processing the imaged media, an enclosed dryer section for drying the media by circulating air thereabout, and extraction rollers for extracting the media from the enclosed dryer section. An improved imagesetting system further includes: an apparatus for drying and lifting the media after extraction from the enclosed dryer section by blowing air along an underside of the extracted media; a stacking surface for stacking the extracted, dried media, where the stacking surface is formed by one or more external surfaces of the imagesetter and the processor and the stacking surface has at least one sloped section; and an indent which extends the stacking surface beneath the extraction rollers in a direction opposite to a direction of movement of the media being extracted, so that the indent prevents binding of trailing edges of the media by accepting sections of the media which abut the trailing edges onto the stacking surface proximate to the indent.

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.

A thermal imaging apparatus includes an internal drum for supporting a receiver material and a donor material in a superimposed relationship, an imaging unit for thermally transferring an image from the donor material to the receiver material, and a material dispensing mechanism for dispensing the receiver and donor materials from a plurality of material supply rolls. A rotatable material supply carousel having a plurality of supply stations for supporting the plurality of supply rolls is provided. A drive system rotates the carousel to sequentially position a selected plurality of the supply stations at a dispensing position.

A media transport bridge is an integral media transport device within an internal drum laser imagesetter that transports media from an imaging area in the drum to an external processor or intermediate buffer. Five pairs of rollers transport the film over the drum. A first stage of the bridge includes a first pair of rollers driven independently so that the first stage is removable and replaceable with a take-up cassette if desired. A friction drive within the imagesetter is adaptable to drive either the first stage or the take-up cassette when installed. Upon removal of the first stage, an automatic adjustment of the bridge is performed to balance the pivotally mounted bridge. The media is moved into the bridge by a pair of drum rollers while the first stage is synchronized with the other four pairs of rollers in the bridge and monitored to keep a slack loop of media at the first stage rollers to eliminate perturbations in the media. A mechanical flag sensor changes state to slow and speed up the bridge rollers to maintain the slack loop.
