14.3.6 Fusing paper transport control
• The 2nd transfer roller transports paper onto the fusing unit.
• The fusing unit uses the fusing motor to drive the fusing pressure roller, thereby transporting paper onto the exit/reverse section.
• Fusing motor speed control is completed before the paper enters the fusing unit.
• The paper fed into the paper exit/reverse section is detected by the paper exit sensor before being transported by the paper exit roller.
• The fusing motor is deenergized after the last sheet of paper is fed into the finisher or out into the exit tray.
