Patent ID: 8565630

Claim:
A method of controlling an image forming apparatus comprising a medium feeder configured to load therein and to pick up and feed a printing-target medium; an image forming unit configured to form an image on the printing-target medium that is picked up and fed; and a fixing unit configured to fix the printed medium on which the image has been formed, the method comprising: heating the fixing unit such that a temperature of the fixing unit reaches a fixing reference temperature corresponding to the printing-target medium if a printing operation is started; sensing the temperature of the fixing unit corresponding to the start of the printing operation and compensating a pickup timing temperature corresponding to whether the sensed temperature thereof is higher or lower than a predetermined first reference temperature, and picking up the printing-target medium when the temperature of the fixing unit that is being heated reaches the compensated pickup timing temperature, wherein the compensating of a pickup timing temperature comprises performing compensation of a value of the pickup timing temperature as a relatively lower temperature if the sensed temperature of the fixing unit is lower than the predetermined first reference temperature.
