The proximity sensor remains on for more than 24 hours (detects presence)

The operator is unable to work properly.

The sensor is damaged and therefore remains in an open state.

Enter user tool mode and set the sensor to 'disabled'. (Default: enabled) Therefore, no fault information will appear before replacing the sensor.

Replace the sensor and its components.

The proximity sensor cannot detect the presence of the operator (always in a closed state), even if the operator has performed 20 operations on the machine: using the operation panel, opening/closing ADF, placing original documents, etc

Open/close the front door, open/close the paper tray. The operator can continue to use the machine (only when the sensor function is disabled).

The sensor is damaged, so it is always in a closed state.

Enter user tool mode and set the sensor to 'disabled'. (Default: enabled) Therefore, no fault information will appear before replacing the sensor.

Replace the sensor and its components.

After the bottom plate lifting motor is turned on to raise or lower the bottom plate, the bottom plate position sensor is not turned on.

-Or-
After the bottom plate lifting motor is turned on to raise or lower the bottom plate, the bottom plate HP sensor is not turned off.

The bottom plate lifting motor raises and lowers the bottom plate on which the original manuscript is placed.

If the output of the bottom position sensor does not change after the bottom rises or falls, the ADF will send a signal to the machine when the problem first occurs, indicating that there is a problem with the ADF's operation.

When the problem occurs for the second time, ADF sends a paper jam error signal.

The bottom plate position sensor has no output result

The in-situ sensor on the bottom plate has no output result

The bottom motor is not running

ADF motherboard malfunction

Check the wiring harness and connectors of the baseplate position sensor and baseplate HP sensor.

Check the wiring harness and connectors of the bottom plate lifting motor.

Replace the bottom plate position sensor.

Replace the original sensor on the base plate.

Replace the bottom plate lifting motor.

• Replace the ADF motherboard.

The paper rolling motor is running, but the status of the paper rolling in-situ sensor has not changed.

Under normal circumstances, the paper picking motor rotates to lower the paper picking roller to the surface of the original manuscript at the top of the raised paper stack, separating and conveying the original manuscript.

The in-situ sensor of the paper roll detects the lifting of the paper roll, but if the sensor has no output, the ADF will send a signal to the host, indicating that there is a problem with the operation of the original paper roll program.

When the problem occurs for the second time, ADF sends a paper jam signal.

Check if the wiring harness and connectors of the in-situ sensor for paper rubbing are damaged. If damaged, replace them.

Check the wiring harness and connectors of the paper rolling motor sensor, and replace them if damaged. Check the ADF motherboard wiring harness and connectors.

Replace the in-situ sensor for paper rubbing.

Replace the paper rubbing motor.

• Replace the ADF motherboard.

During the operation of the feed motor, the machine detected an error signal.

When an error or overload signal is detected in the feed motor encoder register or encoder channel A (B), a problem is detected.

But the second time the problem occurred, the ADF sent a paper jam signal.

After the machine sends the drive command, the encoder pulse does not change, indicating that there is a problem in the encoder channel.

If the PWM duty cycle is consistently higher than the preset value, it indicates an overload error.

Paper jam in the paper path

Motor overload caused by obstruction

Loose, damaged, or defective motor wiring harness

Motor bracket and motor installation errors

Poor paper feeding motor

Check for paper jams, paper scraps, etc. in the paper feeding path.

Check the area around the paper feeding motor and remove all obstacles that may interfere with the motor's operation.

Check if the wire harness and connectors of the paper feeding motor are damaged. If damaged, replace them.

Check if the installation of the paper feeding motor and its bracket is correct.

Replace the paper feeding motor.

The machine detected an error signal during the operation of the motor.

When an error or overload signal is detected in the feed motor encoder register or encoder channel A (B), a problem is detected.

But the second time the problem occurred, the ADF sent a paper jam signal.

After the machine sends the drive command, the encoder pulse does not change, indicating that there is a problem in the encoder channel.

If the PWM duty cycle is consistently higher than the preset value, it indicates an overload error.
