• Check the contents of package for specified quantities of the fol-

lowing items.

3. Remove the front panel of the sorter.

Loosen the four screws which clamp the front panel of the sorter, and remove the front panel.

• Install the sorter in the following procedure, after disconnecting the

power cord of the copier.

1. Mount the linkage paper guide.

Mount the linkage paper guide by hooking its two claws in the paper outlet of the copier as shown below.

2. Install the sorter mount base on the desk.

Cut two notches into the left panel of the desk. Screw two clamp screws of the sorter mount base into the desk. Hook the sorter mount base on the two clamp screws A as shown in the figure. Also attach the sorter clamp fixture on the sorter mount base and clamp it with a clamp screw B.

4. Mount the sorter on the sorter mount base.

Lift the sorter using the handles, and place the sorter on the mounting base with the rollers riding along the guide rails. Slide the sorter gently to the end. Be sure the roller grooves of the sorter are all riding on the guide rails as shown in the detail drawing below.

5. Remove the rear panel of the copier and cut a notch in the left panel.

Unscrew four clamp screws of the copier’s rear panel and remove the rear panel. Then cut a notch in the left panel.

7. Replace the rear panel.

Install the rear panel removed in step 5 to its place, and fasten it with four clamp screws.

8. Install the front panel of the sorter.

Install the front panel removed in step 3 to its place, and fasten it with four clamp screws.

6. Connect the sorter connector.

Temporarily fix one of the two bracket clamp screws, which are packed together with the sorter, into the threaded hole shown below. Hook the lower notch of the bracket on the screw and clamp it on the upper notch with another clamp screw. Tighten the temporarily fixed clamp screw. Connect the 6P and 10P connectors of the sorter with their counterparts of the copier. Fasten the lead wires with twist bands.

9. Adjust the clearance between sorter and copier.

Press the sorter against the left panel of the copier gently. Adjust the clearance between the sorter and the copier by turning the adjust knobs provided on the sorter mount base, using as reference the gap spacer which is attached on the back of the sorter. After adjustment, remove the gap spacer.

1. External view

The above operation makes the current setting displayed.

• If SF-S15 only is to be set, the above operation should be followed

by the following key operation to set the mode.

• If mode setting is to be done in combination with other option, add

the values which correspond to the peripheral devices to be set and enter the sum. ex. To set SF-S15 and SF-A54, key in as follows since the value corresponding to the peripherals to be set is 1 + 10 = 11.

3. Driving mechanism of the transfer section

1. Feeder section

• Copy paper discharged from the copier is fed along the paper

entry guide.

• A paper entry paper sensor is provided halfway along the paper

entry guide to detect the paper entry of paper.

• Feed rollers catch the paper to send it to the transfer section.

2. Transfer section

• The paper passage is switched by a separator claw between one

to the top bin (bin 1) and one to bins 2 through 20.

<Non-sorting operation>

The separator pawl rests on the lower position so that the paper passes over the pawl to be transferr through the discharge rollers into the non-sorting bin (top bin).

Discharge roller

Non-sorting bin (Top bin)

Separator claw (lowers upon solenoid OFF)

Paper

The feed rollers and the discharge rollers are driven by the transfer motor via a high trail pulley, gear 24T, transfer belt, pulley 24T and timing belt.

4. Separator section

• The solenoid-driven separator claw selects the paper passage be-

tween non-sorting and sorting paths.

• When the solenoid is OFF, the separator claw is in the lower

position so that the paper is discharged into the non- sorting bin.

• When the solenoid is ON, the separator claw is in the upper posi-

tion so that the paper is transferred by the suction belt and discharged into bins 2 through 20 by the indexer successively.

Discharge roller

The separator pawl is in the lifted position so that the paper passes under the pawl and is transferred by the suction belt to the indexer which discharges the paper.

6. Roller driving mechanism in the indexer

• Shifting operation of the indexer is driven by the shift motor.

• Indexing is performed by starting and stopping the shift motor

according to the ON/OFF of the Geneva. The sensor detects cuts on the circumference of the Geneva gear while the gear rotates. A half turn of the Geneva gear causes the indexer to make one shift.

• Rotation of the indexer is controlled from the copier.

Provided at top of the indexing mechanism are home position sensor and upper limit sensor (over-run protection). Provided at the bottom is the lower limit sensor.

• The discharge rollers in the indexer are driven by the transfer

motor via the high trail pulley, gear 24T and drive belt.

7. Reel film

• Reel film is stretched between the reel shaft and the indexer.

• The reel film is wound around the reel and is kept tight by a reel

spring.
