Fusing roller drive control
A. Fusing pressure roller rotating speed control
• In order to avoid fusing error, the rotation speed of the fusing belt is exchanged according
to the paper type or the print mode
• By selecting the gloss mode, fusing speed slows down by 50% from the normal speed.
• Fusing speed is set to 80 mm/s during standby mode.
• The fusing motor stops as IH coil is not conducted during power save mode.
