This chapter provides all of the information necessary to install, use, and maintain the duplexer.
About the Duplexer
The duplexer is a customer-installed optional device that enables automatic printing on both sides
of a sheet of paper. The duplexer is designed to be mounted inside the printer, just below the exit
transport in the paper path. The duplexer drives a single-sided print partially out of the exit trans-
port, then reverses the direction and pulls the printed page back into the printer to print the second
side. The printer can image two pages at a time, therefore the duplex unit will process two pages
(sides 1 and 3) then refeed these pages for sides 2 and 4.
