摘要： A system and method for reducing scan line jitter in laser scan systems employing a rotating mirror, including a controller for determining a unique time delay for each mirror facet and controlling laser sources so that video provided by each laser source is delayed in a scan line by the unique time delay corresponding to the mirror facet used in creating the scan line. The controller computes a facet map signature vector corresponding to each mirror facet matches the signature to a previously stored signature and assigns measured distance offset data to the mirror facets based upon the matching.

摘要： A method of controlling a temperature of a print chip of a printhead in an ink jet printer includes providing a memory device within the printer. Ink is emitted from the printhead. Temperature data associated with the print chip during the emitting step is recorded. A thermal resistance value associated with the printhead and/or a thermal capacitance value associated with the printhead is calculated. The calculating is dependent upon the recorded temperature data. The thermal resistance value associated with the printhead and/or the thermal capacitance value associated with the printhead is stored in the memory device. A temperature of the print chip at a future point in time is estimated based upon a number of ink drops to be emitted by the printhead before the future point in time, and the thermal resistance value associated with the printhead and/or the thermal capacitance value associated with the printhead. The thermal resistance and/or the thermal capacitance values vary with the print power, target temperature, and heatsink temperatures. The estimated temperature is compared to a predetermined limit temperature. If the estimated temperature exceeds the predetermined limit temperature, the number of ink drops to be emitted by the printhead before the future point in time is reduced.

摘要： A method of controlling a temperature of a print chip of a printhead in an ink jet printer includes providing the printer with a memory device. The print chip is provided with and at least one ink-jetting resistor. The printhead is provided with at least one substrate heater and a heatsink attached to the print chip. Power is applied to the substrate heater and/or the ink-jetting resistor. Temperature data associated with the print chip is recorded during the applying step. A thermal resistance value of the print chip to the heatsink and/or a thermal capacitance value associated with the printhead is calculated dependent upon the recorded temperature data. The thermal resistance value of the print chip to the heatsink and/or the thermal capacitance value associated with the printhead are stored in the memory device. A temperature of the heatsink is measured based upon the thermal resistance value of the print chip to the heatsink, the thermal capacitance value associated with the printhead, a temperature of the print chip, an ambient temperature, and/or a thermal resistance value associated with the heatsink. A level of power to be applied to the substrate heater is set dependent upon the thermal resistance value of the print chip to the heatsink and/or the thermal capacitance value associated with the printhead, and the temperature of the heatsink.

摘要： Method is disclosed for determining characteristics of a toner cartridge. One aspect is directed to determining the characteristics associated with a quantity of toner in the cartridge, and thus, the method includes the steps directed to determining a home position of an encoded device relative to a code reader, determining a delay in rotational movement of the encoded device with respect to a rotational movement of a drive mechanism as an agitator moves through the toner, and translating the delay into an amount of toner remaining in the cartridge. Another aspect is directed to determining preselected cartridge characteristics from the encoded device, and thus, the method includes steps directed to rotating the encoded device, reading a coding of the encoded device, and decoding the coding to determine the preselected cartridge characteristic information represented by the coding. The method steps directed to these aspects of the method may be performed separately or in aggregate.
