Abstract
An image forming apparatus is provided. The image forming apparatus according to an example includes a print engine including a fuser, a power supply apparatus to selectively provide AC power to the fuser, and a processor to control the power supply apparatus to selectively provide AC power to the fuser, wherein the processor, based on an operation mode of the image forming apparatus being a print mode, performs waveform number control of the AC power provided to the fuser, and, based on the operation mode of the image forming apparatus being an operation mode except for the print mode, performs phase control of the AC power provided to the fuser.
Claims19
An image forming apparatus, comprising:
- a print engine including a fuser, the fuser including a sensor to detect a temperature of the fuser;
- a memory to store a plurality of duties and energization information on each of the plurality of duties;
- a power supply apparatus to selectively provide AC power to the fuser;
- and
- a processor to control the power supply apparatus to selectively provide the AC power to the fuser, wherein the processor;
- determines an operation duty of the fuser according to the detected temperature,
- based on an operation mode of the image forming apparatus being a print mode and based on the determined operation duty being one of the plurality of duties which are stored in the memory, performs waveform number control of the AC power provided to the fuser, and,
- based on the operation mode of the image forming apparatus being an operation mode except for the print mode or based on the determined operation duty being different from the plurality of duties stored in the memory, performs phase control of the AC power provided to the fuser.
A method for providing AC power to a fuser, the method comprising:
- determining an operation duty of the fuser according to a detected temperature of the fuser;
- determining whether the determined operation duty is one of a plurality of duties stored in a memory;
- determining an operation mode of an image forming apparatus;
- performing waveform number control of the AC power provided to the fuser based on the operation mode of the image forming apparatus being a print mode and based on the determined operation duty being one of the plurality of duties which are stored in the memory;
- and
- performing phase control of the AC power provided to the fuser based on the operation mode of the image forming apparatus being an operation mode except for the print mode or based on the determined operation duty being different from the plurality of duties stored in the memory.
A non-transitory computer readable medium including instructions stored thereon to perform a method of providing AC power to a fuser, the non-transitory computer readable medium comprising:
- instructions to determine an operation duty of the fuser according to a detected temperature of the fuser;
- instructions to determine whether the determined operation duty is one of a plurality of duties stored in a memory;
- instructions to determine an operation mode of an image forming apparatus;
- instructions to perform waveform number control of the AC power provided to the fuser based on the operation mode of the image forming apparatus being a print mode and based on the determined operation duty being one of the plurality of duties which are stored in the memory;
- and
- instructions to perform phase control of the AC power provided to the fuser based on the operation mode of the image forming apparatus being an operation mode except for the print mode or based on the determined operation duty being different from the plurality of duties stored in the memory.
