    摘要： A drum heater consisting of a plurality of vanes made preferably from mica material and having multiple separate heater wire channels controlled from an electrical cable is provided for heating the interior of a printer drum or fuser. The drum heater has element wires, which can be operated in two different modes, and which are wound around eight mica vanes. The mica vanes are held together on both ends with mica end caps for assembly, electrical isolation and thermal isolation. The mica vanes additionally define protruding tabs for attachment of wire restraining and protecting mica panels.

    摘要： A heater assembly heats media substrate in a printing system prior to imprinting a desired image on the substrate. A plate member engages the substrate and communicates thermal energy thereto for the heating. A laminar assembly is adhered to the plate member and includes a trace pattern for converting electrical energy to the thermal energy. A thermal storage member is interposed between the plate member and the trace pattern for distributing thermal energy throughout the thermal storage member. Two thermal fuses are serially connected, one at each end of the trace pattern and disposed relative to the thermal storage member for detecting an undesired temperature increase in the laminar assembly sufficient for opening the fuses and electrically isolating the heater assembly against a consequential thermal run-away causing insulation degradation and an electrical short between the trace pattern and the plate member.

    摘要： A phase change ink transfer printing apparatus (10) applies a liquid intermediate transfer surface (12) to a heated drum (14, 28). Because the intermediate transfer surface is a thin liquid layer, molten ink drops (122) striking it flatten and spread out (110, 112, 114, 130) prior to cooling and solidifying as an ink image (26, 130) at the drum temperature. After the ink image is deposited, a print medium (21, 132), such as a transparency film, is fed into a nip (22) formed between the heated drum and an elastomeric transfer roller (23). As the drum turns, the print medium is pulled through the nip to transfer the ink image to the print medium. When in the nip, heat from the drum and print medium combine to heat the ink in accordance with a process window (90), making the ink sufficiently soft and tacky to adhere to the print medium but not to the drum. The ink drops comprising the ink image have a desired diameter to height ratio of from about 1.5:1 to greater than about 4:1 using the apparatus and method of printing disclosed. When the print medium leaves the nip, stripper fingers (24) peel it from the drum and direct it into a media exit path. No image post processing or fusing is necessary to achieve a high-quality print suitable for transparency projection.

    摘要： A method and system for selectively controlling supplied power to an ink melt heater for maintaining a desired ink melt rate despite a varying ambient parameter affecting an actual melt rate. A predetermined amount of power is supplied to the ink melt heater intended to cause the desired ink melt rate. The ambient parameter is detected by the ink melt heater. A determination is made if the detected ambient parameter will cause a variance in the actual ink melt rate from the desired ink melt rate. If a variance is so determined, the supplied power is adjusted from the predetermined amount to an adjusted amount for realizing desired ink melt rate. The ambient parameter preferably comprises sensing a factor representative of at least one of local environmental air temperature to the printing system or adjacent ink temperature to the heat plate.

    摘要： A method and system for detecting an ink stick jam in a solid liquid ink phasing delivery system for supplying ink to a printer. The phasing system includes a heater plate disposed to engage a solid ink stick and heat an engaging portion of the ink stick to a liquid phase. A temperature sensing device associated with the heater plate detects the temperature thereof. A control system selectively supplies power to the heater plate. The method comprises supplying a predetermined amount of power through the control system to the heater plate intended to achieve the desired melt rate of the ink stick during a phase change from solid to liquid. The desired melt rate is associated with the predetermined desired temperature of the heater plate. The temperature of the heater plate is sensed with the sensing device during the supply of power thereto. When a sensed temperature of the heater plate varies from the predetermined desired temperature by a selected amount, the supply power is interrupted, whereby heater damage and printer ink starvation can be avoided.
