AR-RB1  UNPACKING AND INSTALLATION  2 - 4

3) Attach the transport guide to the duplex bypass/inverter unit and

insert the two transport guide holders into the two transport guides
respectively. At this time, ensure that the transport guide holders
are secured at the notch positions.

4) After checking that the transport guide is aligned with the guide of

the stand, close the left cover of the main unit securely.

1) Remove the screw from the power supply cover on the rear side of

the optional stand and then remove the power supply cover.

2) Cut out the portion (indicated with H) of the removed power supply

cover shown in the illustration.

3) Connect the relay harness of the duplex bypass/inverter unit to the

connector of the optional stand.

Then, insert the snap band into the mounting hole shown in the
illustration to secure the relay harness.

4) Pass the relay harness through the cut out hole, hang the two

pawls of the power supply cover on the rear cabinet, and attach the
cover with the screw.

Installation of AR-RB1 is now complete.

AR-RB1  DESCRIPTION OF OPERATION  4 - 1

• The operations include straight delivery, reverse tray delivery, reverse finisher delivery, and ADU delivery (when AR-D19 is installed) operations.

BIM (paper in-motor) changes the transport path of the fed paper when BGSOL (gate solenoid) straight delivery is ON and all other operations are
OFF.

• In the case of straight delivery, BPOD (paper discharge detect) detects the passing paper.

• In the case of reverse tray delivery operation, the paper-in motor and the upper reverse motor operates, the paper is fed, and BPPD1 is detected.

Afterward, the upper reverse motor stops, and the paper transport stops.
Next, the upper reverse motor rotates in reverse to transport paper to the direction of paper exit tray.
After BPOD (paper discharge detect) detects the passing paper, it turns off the upper reverse motor.

• In the case of reverse finisher delivery operation, the same as reverse tray delivery operation.

• In the case of ADU operation, the lower reverse motor operates, and the paper being transported to the reverse roller is detected by BPRD.

After being detected, the lower reverse motor stops, then it rotates in reverse, and the paper is transported to ADU.
After BPPD2 detects the passing paper, it turns off the motor.
