AR-RB1 DESCRIPTION OF OPERATION 4 - 1

[4] DESCRIPTION OF OPERATION

[Outline of operation]

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

[Sensor and solenoid operation]

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.

AR-RB1 DESCRIPTION OF OPERATION 4 - 2

(1) Initial operation

When the power to the copier is turned on, in order to confirm whether

or not there is paper in the transport path, the paper input motor, upper

turnover motor and lower turnover motor revolve for a predetermined

time.

Even after the predetermined time has passed, if all the transport sen-

sors are OFF and it is determined that there is no paper in the trans-

port path, if within a given period of time at least one transport sensor

turned ON, it is interpreted as paper being present in the transport path

(paper jam).

(2) Straight delivery operation

In this operation, the paper discharged from the copier is sent directly

to the paper exit tray or transported to the finisher.

When the paper input motor and upper turnover motor revolve, the

paper input roller and delivery roller rotate in the directions as shown in

the figure below to discharge the paper.

If the paper is delivered to the finisher, it is transported at the same

speed at which it is discharged from the copier.

As the paper is discharged to the paper exit tray, when the trailing

edge reaches a point 50mm from the delivery roller on the copier side,

the speed of the delivery roller increases, and the paper is discharged

to the tray.

(3) Reverse tray delivery operation

A. When paper length is 249mm or less (letter size or less)

(Both the paper input motor and upper turnover motor operate)

The relation between the process speed and the transport speed in

RB1 is as follow.

Unit: mm/s

Sensor input, motor output, solenoid output timing is as below.

Processing speed

The paper input motor and

upper turnover motor are

caused to turn in time with the

copier processing speed, thus

transporting the paper.

When the trailing edge of the paper

reaches a point 13mm from the copier

POD off, the transport speed in RB1

is accelerated.
