摘要： A thermal printer has a dye donor supply spool with a body and first and second end portions extending from the body. First and second receptacles are positioned for matingly receiving the first and second end portions of the dye donor supply spool. The supply spool is correctly loaded only when the first and second end portions of the supply spool matingly engage the first and second receptacles, respectively. A mechanical stop prevents incorrect end for end loading of a supply spool that has an off center web wound thereon by engaging the web and preventing the end of the spool from engaging the receptacle.

摘要： A thermal printer and method for operating a thermal printer are provided. The thermal printer has a receiver medium path leading past a print nip between a print head and platen. A processor causes an urge roller to move the receiver medium in the forward direction until a trailing edge of the receiver medium is moved to a point where reverse movement of the receiver medium causes the receiver medium to located against a stop surface. The processor then enables the receiver medium to travel in the reverse direction to engage the stop surface wherein the receiver medium path guides the receiver medium along a path of known length from the stop surface to a print line at the print nip.

摘要： A printer and method for operating a printer are provided. The printer has a printhead adapted to heat a thermal donor medium to transfer donor material from a donor web to a receiver medium; a receiver medium path having guides shaped to direct receiver medium along a receiver medium travel path to and from a position in registration with the printhead with said receiver medium path having at least one change of receiver medium direction therein causing said receiver medium to bend; and a motorized platen for moving receiver medium through the receiver medium path, wherein said receiver medium path is further shaped so that the change in receiver medium direction occurs in a portion of the receiver medium path that takes the receiver medium from a position in registration with the printhead.

摘要： A printer has a path for a sheet. A donor web is disposed on one side of the path; a platen roller is disposed on the other side of the path and supports the sheet during printing. An edge sensor is located in path at a known distance from the nip of the print head and the platen. Edge sensor senses the lead edge of the sheet and then the control circuit drives the lead edge to a distance D from the heat line of the print head. The head lowers, is selectively energized and the platen moves to carry the donor web and sheet past the head and provide a borderless printed image on the sheet.

摘要： A guide roller assembly is provided for a thermal printer to prevent the varying donor web tension from compromising the constant head load. The guide roller is mounted on a frame that is independent of the head loading assembly so that variations in web tension do not impact the head loading.
