Patent number: 10449783Abstract: In one example, a method for controlling temperature of a print dryer. High power is applied to a heater of the print dryer. A series of temperatures of the print dryer are periodically measured and stored until a target temperature for the print dryer is exceeded. Low power is applied to the heater after the target temperature is exceeded. A rate of temperature change at a time when the target temperature was exceeded is calculated from the stored temperatures. Using the rate, an initial heater duty cycle defining an initial heater power determined. PID control of the heater power is performed, beginning with the initial heater duty cycle, to maintain the print dryer temperature at the target temperature within a predefined accuracy.Type: GrantFiled: April 18, 2018Date of Patent: October 22, 2019Assignee: Hewlett-Packard Development Company, L.

Patent number: 10350888Abstract: A printer includes a printhead configured to eject high viscosity material and refill a reservoir in the printhead with high viscosity material. The printhead includes a transducer having an electroactive element and a member to which the electroactive element is mounted. An electrical signal activates the electroactive element to move the electroactive element and the member in the reservoir of high viscosity material. This movement thins the high viscosity material and enables the printhead to eject the thinned material while refilling the reservoir. The apertures through which the thinned material is ejected share a common manifold without separate chambers for each of the apertures.Type: GrantFiled: December 8, 2014Date of Patent: July 16, 2019Assignee: Xerox CorporationInventors: David A.
