Using the auto-duplex unit
You can print on both sides of a sheet of paper automatically when the auto-duplex unit is
installed on the printer.
For instructions on printing with the auto-duplex unit, see “Printing on both sides (duplexing)”.
Installing the auto-duplex unit
1 Remove the rear access panel by pushing the release buttons towards each other and
pulling the rear access panel out of the printer.
2 Insert the auto-duplex unit straight into the back of the printer until both sides snap into
place.
The auto-duplex unit is a standard part in the hp deskjet 9670. It may be purchased separately
in some countries/regions (see “HP supplies and accessories”).
Do not press the buttons on either side of the auto-duplex unit when installing it. Use these
buttons only for removing the auto-duplex unit from the printer.
