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 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.

摘要： A method and system is provided for more accurately determining ink in-flow and out-flow to a reservoir in a solid-to-liquid ink phasing delivery system for supplying ink to a printer. The printer throughput is safely maximized with a software algorithm that measures the ink available in the printer reservoir for printing. The algorithm is based on the known amount of ink in the reservoir when a level sensor probe is tripped and then calculates additional changes in ink volume. The process is done until the algorithm determines the reservoir volume is below a predetermined minimum level when the level sense probe senses ink. The algorithm calculates the ink leaving the reservoir using an out-flow model based on pixel counting and calculates ink entering the reservoir using an in-flow model based on a minimum guaranteed amount of ink delivered from the melt heater. A time out period is further calculated in which the reservoir should be refilled, and if not, the system is checked for an ink stick jam.

摘要： An ink jet printer includes an ink supply system and a printhead with nozzles for ejecting ink drops. The printer determines the average size of the ejected ink drops by comparing the number of ink drops ejected in a predetermined time with the quantity of ink delivered through the printers ink supply system during that time. If the determined average ink drop size does not match predetermined ink drop size criteria, the printer adjusts the activation signals for the ink jet nozzles to alter the ink drop size. A solid ink printer determines the quantity of ink delivered through the ink supply system by counting the number of whole or partial ink sticks that pass a predetermined point in the ink supply system. The counter detects a sensing element formed on an external surface of the ink stick. Exemplary detectors include a mechanical arm, or a thermistor to detect a change in the printer melt plate temperature due to a change in the cross sectional area of an ink stick being melted.
