ABSTRACT:
Compact printer with quick-loading cassette and method therefor. The invention includes a printer enclosure and a cassette insertable into the enclosure. The cassette includes a dye ribbon supply reel having a dye donor ribbon wound thereabout and a rotatable dye ribbon take-up reel engaging an end portion of the donor ribbon for taking-up the donor ribbon. A curved receiver supply tray is disposed in the cassette for supplying receiver sheets to the printhead which is disposed in the enclosure. The curved receiver supply tray occupies less space, depending on the radius of curvature, than the elongate rectangularly-shaped receiver supply trays of the prior art. Over time, a stack of the receiver sheets residing in the supply tray obtains a curved contour because the stack of receiver sheets conforms to the curved shape of the receiver supply tray. To avoid curling in the finished prints, a platen roller generates radiative heat which is applied to the receiver sheets in order to uncurl the receiver sheets during the printing process.
