Installing the Optional Duplexer

The optional Duplexer can be installed by the customer. There are no fasteners securing the units together. The printer simply rests in place on top of the Duplexer, which, in turn, rests on top of the optional 500-sheet Lower Cassette, if used.

To install the Duplexer, first turn power OFF and disconnect all cables from the printer. Follow the steps below, referring to the corresponding steps illustrated in Figure A-4.

•Open the printer’s rear door and use needle-nose pliers to release the door strap from the printer.

LJ 4 +

•Grasp the plastic retaining clip and lift it upward and away from the door.

•Slide the door toward the left.

•Swing the right end of the door out from the printer and slide it toward the right to free it from its hinge.

LJ 5

•Flex the rear door to release it from its hinges. (Press the middle of the door while lifting either side.)

•Place the Duplexer on a flat surface and tilt the Switchback Assembly partially back.

•Verify the alignment pins on the Duplexer mate with the holes in the bottom of the printer, and if used, the top of the optional 500-sheet Lower Cassette. Place the printer on top of the Duplexer.

•Close the rear door (Switchback Assembly) and plug in all cables - note routing of the power cables as shown.

N o t e	Removal of the Duplexer from the printer is the
	reverse of installation - simply unplug cables,
	unlatch the Switchback Assembly, and lift the
	printer off the top. If the optional 500-sheet
	Lower Cassette is being used, lift the duplexer off
	the Lower Cassette.
	For further information, refer to the illustrated
	steps in Figure A-4 on the next page.
