Abstract
Disclosed are embodiments for controlling one or more subsystems of an imaging system to manage average power to a fuser.
Claims78
An apparatus comprising:
- a power sensing circuit to detect a level of power being drawn from a power source by one or more subsystems included in an imaging system;
- and
- a controller to configure said apparatus to change an amount of power being drawn from said power source by a fuser in response to said detected level of power to limit the average power to the fuser.
A method comprising:
- supplying power from a power source to one or more subsystems comprising a printing system;
- monitoring a level of power drawn from said power source;
- and
- configuring said printing system to change an amount of power being drawn from said power source by a fuser in response to said level of power to control the average power to the fuser.
1 more element
An apparatus comprising:
- means for supplying power from a power source to one or more printer subsystems of a printing system, said one or more subsystems comprising at least an imaging device to transfer an image to media;
- means for monitoring a level of power drawn from said power source;
- and
- means for configuring said printing system to change an amount of power being drawn from said power source by a fuser in response to said detected level of power to control the average power to the fuser.
1 more element
An apparatus comprising:
- a plurality of subsystems including an imaging device and a fuser to fix an image to imaging media, at least in part, on image data;
- a power supply to provide a converted power signal to one or more of said subsystems in response to a power signal from a power source;
- a power sensing circuit to measure a level of power being drawn from said power source;
- and
- a controller to increase and/or decrease a level of power provided to at least one said fuser based, at least in part, on said measured level of power drawn from said power source to limit the average power to the fuser.
2 more elements
An article comprising:
- a storage medium comprising machine-readable instructions stored thereon to:
- monitor a level of power drawn from a power source for powering one or more subsystems of a printing system, said one or more subsystems comprising an imaging device to transfer an image to media;
- and
- configure said printing system to change an amount of power being drawn from said power source by a fuser in response to said level of power to limit the average power to the fuser.
1 more element
A system comprising:
- a plurality of subsystems comprising at least:
- a media input unit to sequentially dispense sheets of imaging media;
- an imaging device to transfer images to imaging media dispensed from said media input unit based, at least in part, on image data;
- and
- a media output unit to receive said imaging media having images transferred thereon;
- a power supply to provide a converted power signal to one or more of said subsystems of in response to a power signal from a power source;
- a power sensing circuit to measure a level of power being drawn from said power source;
- and
- a controller to increase and/or decrease a level of power to at least one of said subsystems based, at least in part, on said measured level of power drawn from said power source to limit the average power to the fuser.
6 more elements
A method comprising:
- detecting a fuser under-temperature condition of an imaging device, said imaging device being among a plurality of subsystems of a printing system;
- and
- reducing power provided to at least one of said subsystems in response to detecting said fuser under-temperature condition in a manner which limits the average power to the fuser.
An apparatus:
- means for detecting a fuser under-temperature condition of an imaging device, said imaging device being among a plurality of subsystems of a printing system;
- and
- means for reducing power provided to at least one of said subsystems in response to detecting said fuser under-temperature condition in a manner which limits the average power to the fuser.
An article comprising:
- a storage medium comprising machine-readable instructions stored thereon to:
- detect a fuser under-temperature condition of an imaging device, said imaging device being among a plurality of subsystems of a printing system;
- and
- reduce power provided to at least one of said subsystems in response to detecting said fuser under-temperature condition in a manner which limits the average power to the fuser.
1 more element
An apparatus comprising:
- a circuit to detect a fuser under-temperature condition of an imaging device;
- and
- a controller to configure an imaging system to change an amount of power being drawn from a power source in response to said detected fuser under-temperature condition in a manner which limits the average power to the fuser.
A method comprising:
- receiving power at a printing system from a power source;
- distributing said received power among one or more subsystems of said printing system;
- detecting one or more lapses in said receipt of power at said printing system over a predetermined period;
- and
- reducing an amount of power being provided to said one or more of said subsystems in response to detecting said one or more lapses in a manner which limits the average power to the fuser.
