20080278561 | Thermal printer with reduced donor adhesion - Thermal printers and methods for operating thermal printers are provided. In one method, a sequence of thermal print head control signals is generated that is adapted to cause an array of thermal elements to cause the donor material to transfer from a donor ribbon in a manner that is modulated in accordance with image data and attenuated in accordance with an attenuation pattern. A receiver medium is urged through the printing nip while the thermal print head control signals are transmitted to the thermal print head to cause the donor material to transfer from the donor web in an image modulated pattern having a longitudinal length that is larger than a longitudinal length of the receiver medium. The attenuation pattern provides a relatively high level of attenuation at a portion of the printing wherein there is greater risk that the receiver medium will not be within the printing nip. | 11-13-2008 |
20090111037 | PROTECTIVE OVERCOAT TRANSFER COMPENSATION - Observable matte-finish indicia on a printer medium having a matte finish includes the steps creating a matte image-viewing area; creating a glossy finish region within the image-viewing area; creating indicia having a matte finish within the glossy region. The printing medium has a dye-receiving element; and the steps of controlling the specularity of the image-viewing area, the glossy region, and the indicia include the step of imagewise-heating a donor element comprising a support having thereon a laminating patch of overcoat material, the donor being in contact with the dye-receiving element to thereby thermally transfer a layer of overcoat material to the printing medium, the overcoat material layer being transferred using a predetermined energy level within the image-viewing area and the indicia in order to create a matte finish and using a different energy level within the glossy region to create a gloss finish. | 04-30-2009 |
20090123207 | SPOOL ADAPTER - An adapter for a spool includes a body having a first body portion and a second body portion that are slidably joined together. The first and second body portions are slidably adjustable to each other. The first body portion includes a first contact surface and a second contact surface comprising at least one projection adaptable for joining to the spool. | 05-14-2009 |
20100026776 | THERMALLY CONDUCTIVE, ELECTRICALLY ISOLATED PEEL MEMBER ASSEMBLY - A thermal printer having reduced electrical charge built at point of separation of a donor web and a receiver web, includes at least one thermal printhead and at least one platen roller with a nip is formed between the at least one thermal printhead and the at least one platen roller through which the donor web and the receiver web are drawn. A heat sink is attached to the at least one thermal printhead and a peel member is located downstream of the nip. The peel member is substantially electrically isolated from ground. | 02-04-2010 |

20130342625 | ROLL-FED DUPLEX THERMAL PRINTER - A roll-fed duplex thermal printing system, comprising a supply roll of receiver media, a printing path, a reversing path, a diverter and a cutter positioned between the diverter and the reversing path. When the diverter is in a first position the receiver media is directed from the supply roll or the reversing path into the printing path. When the diverter is in a second position the receiver media is directed from the supply roll into the reversing path. During a printing operation, the diverter is positioned in the first position and the receiver media is fed into the printing path where a first side image is printed. The diverter is then repositioned the receiver media is fed into the reversing path where it is cut. The diverter is then repositioned again and the receiver media is fed into the printing path where a second side image is printed. | 12-26-2013 |
20130342626 | ROLL-FED DUPLEX THERMAL PRINTING SYSTEM - A roll-fed duplex thermal printing system, comprising a supply roll of receiver media, a printing path, a reversing path, a diverter and a cutter positioned between the supply roll and the reversing path. When the diverter is in a first position the receiver media is directed from the supply roll or the reversing path into the printing path. When the diverter is in a second position the receiver media is directed from the supply roll into the reversing path. During a printing operation, the diverter is positioned in the first position and the receiver media is fed into the printing path where a first side image is printed. The diverter is then repositioned the receiver media is fed into the reversing path where it is cut. The diverter is then repositioned again and the receiver media is fed into the printing path where a second side image is printed. | 12-26-2013 |
20140055548 | DUPLEX THERMAL PRINTER WITH PIVOTABLE DIVERTER - A roll-fed duplex thermal printing system, comprising a supply roll of receiver media, a printing path, a reversing path, a pivotable diverter and a cutter positioned between the supply roll and the reversing path. When the diverter is in a first position the receiver media is directed from the supply roll, when the diverter is in a second position the receiver media is directed from the supply roll into the reversing path, and when the diverter is in the third position the receiver media is directed from the reversing path into the printing path. During a printing operation, the diverter is sequentially repositioned to feed the receiver media into the printing path where a first side image is printed, into the reversing path where it is cut, and into the printing path again where a second side image is printed. | 02-27-2014 |
20140085394 | DUPLEX THERMAL PRINTER WITH PIVOTABLE DIVERTER - A roll-fed duplex thermal printing system, comprising a supply roll of receiver media, a printing path, a reversing path, a pivotable diverter and a cutter positioned between the diverter and the reversing path. When the diverter is in a first position the receiver media is directed from the supply roll, when the diverter is in a second position the receiver media is directed from the supply roll into the reversing path, and when the diverter is in the third position the receiver media is directed from the reversing path into the printing path.
