ABSTRACT:
Printer adapted to guide a dye donor therein and method therefor. The dye donor ribbon has a leading end portion, which in turn has a plurality of sprocket holes spaced along parallel side portions of the leading end portion. A print head activates the dye donor ribbon to transfer dye therefrom onto a receiver for forming an image on the receiver. A dye donor ribbon take-up spool is disposed near the print head for taking-up the dye donor ribbon as the print head activates the dye donor ribbon. The take-up spool has a plurality of sprockets therearound sized to engage the sprocket holes in the leading end portion. A dye donor ribbon supply spool is spaced-apart from the take-up spool for supplying the dye donor ribbon therefrom as the print head activates the dye donor ribbon. A pair of spaced-apart oppositely disposed parallel guide rails extend between the take-up pool and the supply spool. Each of the rails defines a passage for guiding the dye donor ribbon along the passages. A support roller is disposed adjacently opposite the print head for supporting the receiver on the support roller in engagement with the dye donor ribbon as the print head activates the dye donor ribbon.
