• Duplex Clutch (Duplex In Clutch Assembly) - Transfers the drive of the Duplex Motor to the Exit
Roller that is part of the Fuser Assembly. Normally, the Exit Roller rotates in the paper output
direction by the drive of the Fuser Motor. When the paper is to be reversed for side 2 print, the
Duplex Clutch activates, changing the drive source to the Duplex Motor so that the Exit Roller
performs reverse rotation in the Duplex Assembly direction.
• Duplex Motor (Duplex Earth Motor Assembly) - Drives the Duplex 1 Roller and Duplex 2 Roller to
transport the paper in the Duplex Assembly.
• Duplex Jam Sensor - Detects whether the paper is being transported in the Duplex Assembly by
changes in the Actuator.
(No paper: Sensor blocked)
