Abstract
A color printer for thermally transferring a set of monochrome images of each desired color reproduction from a color transfer strip to a recipient sheet as the latter is fed back and forth by and past a platen roll disposed intermediate a sheet loading cassette and a sheet unloading cassette. The printer additionally comprises a thermal printing head for pressing the transfer strip, in superposition with each recipient sheet fed from the loading cassette, against the platen roll for thermal ink transfer, and a pinch roller disposed upstream of the printing head, with respect to the traveling direction of the recipient sheet from the loading cassette to the unloading cassette, for pressing the recipient sheet against the platen roll. For more precise registration of the monochrome images of each color reproduction, a retractable end abutment is disposed between printing head and pinch roller. The recipient sheet stands endwise on the end abutment before being fed forwardly past the platen roll for the transfer of each monochrome image. A lateral sheet readjustment mechanism is disposed upstream of the end abutment for readjusting the lateral position of the recipient sheet, standin…
