Drive Power Transmission
The optional Duplex Assembly has its own motors (Motor Assembly Dup and Motor Assembly
Exit) for paper transportation. The drive power generated by the Motor Assembly Dup is trans-
mitted to the paper driving rolls in the Duplex Assembly through the drive gears and belt. This
drive power is used to transmit the paper through the path toward the Registration Roll after
receiving the return paper from the Exit Assembly. The drive power generated by the Motor
Assembly Exit is transmitted to the paper driving rolls in the Duplex Assembly and Exit Assem-
bly. This drive power is used to deliver the paper from the Exit Assembly to the Duplex Assem-
bly and discharge it from the Exit Assembly after the completion of side 2 printing.
