A new fusing technology using EDLC (Electric Double Layer Capacitor) power assistance has been developed which greatly reduces the warm-up time and energy consumption. The charged power of EDLC is used for heating energy of fusing unit. The power assistance can be used for the temperature drop during the early stage of the continuous paper feeding. Furthermore, it is applicable to the acceleration of temperature rise of the fuser roller for start-up or recovery stage.The technology is adopted in high-speed MFP from Ricoh.
