ABSTRACT:
Apparatus for maintaining tension on a ribbon in a printer used for transferring an image, e.g., thermally, from a print head through the ribbon to a print medium. By maintaining ribbon tension and thus keeping the ribbon essentially without wrinkles, print quality is enhanced. This tension maintenance apparatus uses a pair of torqued reel subassemblies with the ribbon extending between and is of particular significance when used in conjunction with a label stock as a printer medium when the printer mechanism bidirectionally moves the label stock to assist removal of labels from its backing. These torqued reel assemblies are sufficiently loaded such that ribbon tension is maintained between these reel assemblies despite this bidirectional movement.
