Principles of Operation
For Duplex printing, the paper travels further into the duplex path to a “dup point.” At this posi-
tion, the paper has passed a second Mylar gate. The copy reverses direction, driven by the
Duplex Invert
er Roll, and the Mylar gate guides the paper to the Dup Path. Two sets of pre-
alignment rolls (Duplex In Roll and Duplex Path Roll) drive the copy, while three sets of crossed
rolls (Alignment Rolls 1, 2 and 3) push the copy into the Side Guide Rail for alignment prior to
copying on the second side.
Duplex Out Rolls transport the copy to the Preregist
rat
ion Rolls. From there, the copy is again
de-skewed and sent for copying on the second side by passing through the IBT, Fuser and then
exiting the machine as a finished duplex copy.
Refer to T
able 1 f
or information on the different drive motors used to transport the paper
through the machine.
