Unplug the copier’s power cord before carrying out the following procedure.

Carry out the following steps before installing the AR-FN2.

1. Pull out the exit unit of the copier until it stops.

2. Remove the two exit area cover fixing screws and remove the exit area cover.

3. Remove the two transport springs that are attached to the exit paper guide.

4. Store the two removed transport springs by hanging on the exit unit front frame (position in Fig. 1).

5. Reattach the exit area cover to its original position and secure it using two fixing screws.

6. Insert the exit unit into the copier.

4. Attach the lock plates.

Cut out the three lock plate mounting holes on the copier using a Phillips screwdriver or the like and remove the burrs using a flat-blade screwdriver or the like.

Then remove the screw from the left cabinet of the copier and secure the lock plates to the copier as shown in the figure using screws B (one for each plate) and positioning screws (one for each plate). (Be careful about the orientation of the lock plates.)

5. Connect the finisher with the copier.

Cut out the two mounting holes at the lower part of the desk (leftmost hole and third hole from the left) using a Phillips screwdriver or the like and remove the burrs using a flat-blade screwdriver or the like.

Secure the mounting plate that is attached to the finisher connecting plate to the lower part of the desk using two screws C.

7. Check and adjust the height of the finisher.

Move the finisher toward the copier, and check and adjust the height so that the guide pin of the copier is inserted smoothly into the positioning hole of the finisher.

6. Connect the finisher connector.

Cut the connector cover for connection of the finisher relay harness connector on the copier using nippers.

Then connect the finisher relay harness connector to the connector on the copier and secure the connector by tightening the screw on the connector.

· Since adjustment has been made at shipping, this adjustment

is basically not needed. If the guide pin should not be inserted smoothly, adjust the height using the following procedure.

<1> Push the finisher into the copier.

Then, rotate the adjusting screw on the rear side of the finisher lower part (Fig. 1) so that length b of the lock plate and lock pawl on the rear side is within the lock plate and lock pawl on the front side.

<2> Push the finisher into the copier.

At this time, check to see if the clearance between the lower part of the finisher and the copier is approximately 1 mm (small clearance).

Approximately 1 mm

If the finisher touches the copier or the clearance is too large:

Adjust the clearance by rotating the adjusting screw that is attached to the paper exit side of the lower part of the finisher (Fig. 2).

· If the finisher touches the copier or the finisher is not locked:

Rotate the adjusting screw clockwise so that the clearance between the lower part of the finisher and the copier is approximately 1 mm.

· If the clearance is too large:

Rotate the adjusting screw counter-clockwise so that the clearance between the lower part of the finisher and the copier is approximately 1 mm.

8. Stick a stapling position label.

Insert the power plug of the copier to an outlet, turn the power switch to the "ON" position and then perform the following procedure.

Finisher operation check

· Check the operation in the staple mode.

Make 10 copies in the staple mode and check that the copies are stapled properly.

If the copies are not stapled at this time, use the following procedure to feed staples to the tip.

1. Open the stapler cover of the finisher.

2. Remove the staple cartridge.

Raise the staple cartridge release lever of the stapler unit to remove the staple cartridge.

5. Set the staple cartridge.

Open the stapler cover of the finisher and set the staple cartridge in the stapler unit.

Insert the cartridge securely until it clicks. Close the stapler cover.

Installation of the finishe r is now com plete.

3. Close the stapler cover of the finisher and remove the copies.

After removing the staple cartridge, close the stapler cover of the finisher.

Then remove the copies from the finisher.

4. Check the staple cartridge.

Check that the first staple is at the STAPLE TEAR line of the cartridge before setting the cartridge.

· If the first staple does not reach the STAPLE TEAR line, pull it

to the line.

· If the first staple protrudes past the STAPLE TEAR line, tear

the staples and align the first staple with the line.
