E-QSU (Enhanced-Quick Start Up) fusing
This fusing unit has the heat conduction plate added to the pressure pad on the fusing nip and removed the shield plate control.
The model of 35 cpm or below require little amount of heat, so it controls the temperature by the heat conduction plate and lamp control at the edges and center.
The heat conduction plate on the nip (on the surface of the pressure pad) disperses the temperature deviation between the front and rear parts of the fusing sleeve belt, so as to even out the temperature.
A fusing sleeve belt is driven by drag rotation following a pressure roller, and presses a nip pad against the pressure roller to fix toner on the paper.
The fusing lamp heats the fusing sleeve belt, and the area of the belt which is heated moves in an anticlockwise direction so that heat is transmitted up to the contact point with the pressure roller.
