Publication number: 20190384543Abstract: A method for reducing a time-to-first-print in an imaging device that includes tracking a set of sleep times between print jobs in an imaging device and determining whether a predetermined number of sleep times in the set of sleep times is reached; and upon a positive determination, identifying a first and a second most recent sleep times stored among the set of sleep times tracked; determining whether each of the first sleep time and the second sleep time is less than a predetermined threshold; and upon a positive determination, determining a value based on an average of the first sleep time and the second sleep time. The value is used as a period of time that the imaging device is powered at a snooze mode prior to transitioning to a sleep mode, and when a print job is received in the imaging device while in the snooze mode, the time-to-first-print from the snooze mode is faster than the time-to-first print when the print job is received while in the sleep mode.Type: ApplicationFiled: June 15, 2018Publication date: December 19, 2019Inventors: David J. Mickan, Kevin D. Schoedinger, William Shannon Spencer

Patent number: 8043470Abstract: The present invention relates generally to plasma processing chambers and electrode assemblies used therein. According to one embodiment, an electrode assembly comprises a thermal control plate, a silicon-based showerhead electrode, and a probe assembly comprising an electrically conductive probe body and a silicon-based cap. The electrode assembly is configured such that the handedness of a threaded engagement of the silicon-based cap and a head section of the probe body and the handedness of the threaded engagement of the thermal control plate and a mid-section of the probe body have a common direction of rotation. Thereby, an application of torque to the silicon-based cap in a tightening direction of rotation tightens both threaded engagements. Further, the electrode assembly is configured such that the threaded engagement of the silicon-based cap and a head section of the probe body permits repetitive non-destructive engagement and disengagement of the silicon-based cap and the probe body.Type: GrantFiled: November 21, 2007Date of Patent: October 25, 2011Assignee: Lam Research CorporationInventors: Randall A. Hardin, Jon Keihl, Shannon Spencer

Patent number: 6299273Abstract: 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.Type: GrantFiled: July 14, 2000Date of Patent: October 9, 2001Assignee: Lexmark International, Inc.Inventors: Frank Edward Anderson, Stanley Dyer, Christopher Dane Jones, Shirish Padmaker Mulay, William Shannon Spencer
