Abstract
A method of controlling a fuser assembly within an image forming apparatus having a fuser assembly including a heating member and a backup member cooperating with the heating member to form a nip therebetween for fusing images onto substrates passing through the nip. The method is provided to minimize or avoid a temperature droop condition of the fuser and includes the steps of determining a set point temperature for performing a fusing operation, and determining whether the image forming apparatus has transitioned from a standby mode to a print mode upon receipt of a print job. If a sensed temperature of the fuser is within a temperature range having an upper threshold temperature that is less than the heating temperature and greater than the set point temperature or a lower threshold temperature, a power control for the fuser is switched to operate in a high power region, increasing power to the fuser, to provide heat energy to the heating member.
