HP LaserJet 42X0/43X0 Series - (Multiple Language) Duplexer Install Guide

See the use guide on the CD-ROM that
came with the printer for information about
gaining access to the printer driver, setting
the control panel, using the duplexer, and
solving problems, and for warranties and
regulatory statements.
To remove the duplexer: Turn the printer so
that the rear cover faces you. Lift up and pull
out to remove the duplexer.
Install the duplex-slot cover if the printer is
going to be used without the duplexer.
