[4] UNPACKING AND INSTALLATION
1.AR-DU3
<Before installation>
•Carry out the installation after checking that the DATA indicator on the
operation panel is neither lit nor blinking.
•For installing AR-DU3, an optional desk (multi purpose drawer, stand/3 x
500 sheet paper drawer or stand/MPD & 2000 sheet drawer) must have
been installed.
•Ensure that the front mounting plates and the rear mounting plates
included with the optional stand/paper drawer are securely attached.
•Check that the left adjuster supplied with an optional stand/drawer has
been attached.
1) Turn off the main switch of the main unit of the printer.
Turn the main switch located on the front side of the main unit of the
printer to the "OFF" position.
Then, remove the power plug of the main unit of the printer from the
outlet.
2) Remove the left side cover of the main unit of the printer.
Unlock the lock release lever of the main unit of the printer and then
pull out the left door.
Slide the two upper covers up to remove them. Remove the lower
cover by inserting a flat-blade screwdriver at three locations ( )
shown in the illustration.
Then, close the left door.
3) Attach the duplex module to the main unit of the printer.
<1>Hang the hooks located at the upper part of the duplex module on
the openings of the left door of the main unit of the printer.
<2>Push the lower part of the duplex module to insert the positioning
bosses securely into the main unit of the printer.
<3>Tighten the two screws built in the duplex module.
4) Connect the harness to the main unit of the printer.
<1>Remove the screw that fixesthe harness cover ofthe main unit of the
printer and then slide the harness cover up to remove it.
<2>Process the harness cover as shown in the illustration.
<3>Connect the connector of the relay harness of the duplex module to
the CN12 (white connector) of the PCU PWB of the main unit of the
printer.
<4>Insert the snap bands to the locations shown in the illustration and fix
them.
<5>Secure the earth harness using a supplied M4 screw.
<6>Reattach the harness cover to its original position and fix it with the
removed screw.
