  • Publication number: 20210046769
    Abstract: Power allocation in printing devices is disclosed. Independent load requests are received from printing device heater systems. Power grants are allocated based on a general power arbitration of a power source in response to the independent load requests. A power grant is adjusted based on a contextual printing condition to provide an adjusted grant from the power source to a printing device heater system of the printing device heater systems. The adjusted grant is based on a power grant limit corresponding with the contextual printing condition.

  • Publication number: 20200270081
    Abstract: In some examples, velocity and torque based media motor control may include ascertaining a velocity and torque for a feed roller motor associated with a feed roller, and ascertaining a velocity and torque for a drive roller motor associated with a drive roller that is to receive media from the feed roller. Further, velocity and torque based media motor control may include determining whether the torque for the drive roller motor is greater than a torque target. In response to a determination that the torque for the drive roller motor is greater than the torque target, the torque for the drive roller motor may be reduced to the torque target, and the torque for the drive roller motor may be maintained at the torque target.

  • Patent number: 10723146
    Abstract: According to an example, a printing system may include printing components, an input voltage engine to determine whether an input voltage level is outside of a predetermined voltage level range, and a printing components engine to control the printing components to operate in one of a normal mode and a reduced throughput mode based upon whether the accessed input voltage level is outside of the predetermined voltage level range.

  • Patent number: 10449783
    Abstract: 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.

  • Publication number: 20130025391
    Abstract: Example embodiments disclosed herein relate to gear backlash compensation in a printing device. This gear backlash compensation occurs in a gear train assembly utilized to drive and position a service station of the printing device. The gear train assembly is driven by a media advance and positioning subsystem of the printing device.
