Abstract
An apparatus and method for controlling power of a fixing unit is provided. The apparatus includes a power supply unit supplying DC power to the fixing unit, and a power controller controlling the power supply unit to gradually increase a DC power supply time until a pre-set time is reached. Accordingly, a flicker characteristic can be reduced by gradually increasing a supply time of DC power to the fixing unit.
Claims21
An apparatus for controlling power of a fixing unit, the apparatus comprising:
- a power supply unit to supply direct current (DC) power to the fixing unit for heating the fixing unit to reach or maintain a threshold temperature to fix a developer onto a print medium;
- and
- a power controller to control the power supply unit to gradually increase a DC power supply time until a pre-set time is reached and supply the maximum power until a temperature of the fixing unit reaches the threshold temperature after the pre-set time has passed.
A method of controlling power of a fixing unit, the method comprising the steps of:
- receiving DC power for heating the fixing unit to reach or maintain a threshold temperature to fix a developer onto a print medium;
- and
- controlling a supply time of the DC power to the fixing unit to be gradually increased until a pre-set time is reached and supply the maximum power until a temperature of the fixing unit reaches the threshold temperature after the pre-set time has passed.
A non-transitory computer readable recording medium having embodied thereon a computer readable program for executing a method of controlling power of a fixing unit, the method comprising the steps of:
- receiving DC power for heating the fixing unit to reach or maintain a threshold temperature to fix a developer onto a print medium;
- and
- controlling a supply time of the DC power to the fixing unit to be gradually increased until a pre-set time is reached;
- wherein in the controlling, the maximum power is controlled to be supplied until a temperature of the fixing unit reaches the threshold temperature after the pre-set time has passed.
