METHOD OF CONTROLLING FUSER UNIT OF IMAGE FORMING APPARATUS ABSTRACT OF THE DISCLOSURE A method of controlling a fuser unit of an image- forming apparatus such as a laser printer, in a warming-up stage, so that excess mechanical and electro- static stresses are not imposed on the process elements (216, 220, 226). The method comprises the steps of: starting the energization of a heater (310) of the heat roller (10) substantially at the same time as the commencement of an initialization process of mechanical and electrostatic conditions of the machine while rotating the heat roller (10) and the backup roller (12) together; stopping the rotation of the rollers (10, 12) after the initialization process has been completed; monitoring a surface temperature of the heat roller (10) for a first predetermined period (T1 - T9) after the completion of the initialization; and if the surface temperature has reached a set value within the first predetermined period, determining that the fuser unit (14) is ready for operation, and conversely, if the set value is not reached within the predetermined first period (T1 - T9), carrying out an additional warming-up process of rotating the heat roller (10) and the back-up roller (12) again until the set value is reached, unless a second predetermined period (T6 - T1) has expired subsequent to the expiration of the first predetermined period (T1 - T9).
