The machine's fixing system is an ondemand type, and its fixing assembly consists of the fixing film unit and the

pressure roller: the fixing film has a builtin fixing heater, thermistor, and thermal fuse.

The toner transferred to paper is heated by the fixing heater, which provides heat through the fixing film; the toner

is forced under the pressure roller so that it is fused into the fibers of the paper under both heat and pressure.
