In offices in which color network MFPs simultaneously serve the needs of multiple users, stable high-speed performance is a must. Through the integration of IH (Induction Heating) technology, commonly used in cooking appliances, and a new concept employing two belts to deliver faster output and enhanced stability, Canon developed the Twin Belt Fixing method.

The fixing system utilizes a fixing belt that heats toner from the front side of the paper, and a pressure belt that applies pressure to the paper from the back. Unlike the rollers found in conventional systems, the belts expand the area on which pressure is applied from a line to a plane, enabling significantly improved fixing stability during high-speed output. The most significant feature is the heating of the fixing belt from the outer side (the side that comes into contact with the paper) using an IH heating coil. Also, since the fixing belt is made of a low-thermal-capacity material, the system achieves approximately 20% greater thermal efficiency than conventional systems while consuming less power.
