ABSTRACT:
A method for controlling the fusing temperature and blower speed based on toner coverage computed from data to be printed and apparatuses using the same. The apparatus for controlling a fusing temperature based on a computed toner coverage has a memory for storing a reference fusing temperature by toner coverage, a fusing temperature determining part for computing the toner coverage of the data, and determining the temperature corresponding to the computed toner coverage about the reference temperature, and a heater. The apparatus for controlling of blower speed based on a computed toner coverage has a memory for storing a reference blower speed by toner coverage, a blower speed determining part for computing the toner coverage of the data, and determining the speed corresponding to the computed toner coverage about the reference speed, and a driver for varying the blower speed to the determined blower speed.
