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.
Claims15
A method, comprising:
- receiving a plurality of independent load requests from each of a plurality of printing device heater systems;
- allocating a plurality of power grants based on a general power arbitration of a power source in response to the plurality of independent load requests;
- and
- adjusting a power grant of the plurality of power grants based on a contextual printing condition to provide an adjusted grant from the power source to a printing device heater system of the plurality of printing device heater systems, the adjusted grant based on a power grant limit corresponding with the contextual printing condition.
A printing device, comprising:
- a conditioning system having a plurality of heater systems, each of the plurality of heater systems to provide an independent load request;
- a power source operably coupled to the conditioning system, the power source to provide a power output to the plurality of heater systems;
- and
- a controller operably coupled to the plurality of heater systems and the power source to distribute the power output between the plurality of heater systems, the controller to:
- receive the independent load requests from the plurality of heater systems;
- allocate a plurality of power grants based on a general power arbitration of the power source in response to the independent load requests;
- and
- adjust a power grant of the plurality of power grants based on a contextual printing condition to provide an adjusted grant from the power source to a heater system of the plurality of heater systems, the adjusted grant based on a power grant limit corresponding with the contextual printing condition.
A non-transitory computer readable medium to store computer executable instructions to control a processor to:
- receive a plurality of independent load requests from each of a plurality of printing device heater systems;
- allocate a plurality of power grants based on a general power arbitration of a power source in response to the plurality of independent load requests;
- and
- adjust a power grant of the plurality of power grants based on a contextual printing condition to provide an adjusted grant from the power source to a printing device heater system of the plurality of printing device heater systems, the adjusted grant based on a power grant limit corresponding with the contextual printing condition.
