Fault Description

The B-Film indicator shows the current status of the bottom film (B-Film) in the laminating machine. When an issue occurs, it may appear in one of the following ways:

1. B-Film indicator does not light up at all: After installing the B-Film, the indicator remains off.

2. B-Film indicator flashes red: The indicator flashes red to signal an error and may be accompanied by an audible alarm.

3. B-Film indicator and Status light flash simultaneously: Both indicators flash at the same time and are accompanied by a buzzer alarm.

4. B-Film indicator shows green but the state is incorrect: The indicator appears normal, but the actual B-Film status does not match.

5. B-Film indicator flashes on and off intermittently: The indicator state is unstable and changes frequently.

Possible Causes

B-Film Indicator Does Not Light Up

1. B-Film not installed: The B-Film roll is not placed correctly in the film compartment.

2. Sensor C not triggered: The swing arm and microswitch sensor do not detect the presence of the film.

3. Film not threaded correctly: The film has not been routed through the roller system properly.

4. Film tension too low: Insufficient tension prevents the sensor from being triggered.

B-Film Indicator Flashes Red

1. B-Film depleted: Sensor D detects that the B-Film has run out.

2. Incorrect B-Film installation: The film roll is not installed or secured correctly.

3. Sensor failure: Abnormal detection by Sensor D (Hall sensor).

B-Film Indicator and Status Light Flash Together

1. Initialization incomplete: The B-Film installation process was not completed successfully.

2. Multiple sensor abnormality: Sensors C and D are both reporting errors.

3. Incorrect film specification: An incompatible B-Film roll has been installed.

4. Mechanical fault: Damage to the film reel, holder, or related components.

Troubleshooting Steps

Step 1 – Check B-Film Installation

1. Open the B-Film hatch cover.

2. Confirm that the B-Film roll is correctly placed inside the film compartment.

3. Ensure the film roll is securely fixed and not loose.

4. Verify that the B-Film specifications are compatible with the machine.

Step 2 – Check Film Threading and Condition

1. Confirm that the film is routed correctly through the roller system.

2. Verify that the film path is correct and unobstructed.

3. Ensure the film has adequate tension.

4. Check whether the film is damaged, torn, or broken.

Step 3 – Inspect and Clean Sensors

Sensor C (Swing Arm + Microswitch)

1. Locate Sensor C.

2. Remove dust, debris, or residue from the sensor area.

3. Check that the swing arm moves freely.

4. Confirm that the microswitch triggers normally when film is present.

Sensor D (Hall Sensor)

1. Locate Sensor D.

2. Clean the area around the sensor.

3. Check that the sensor cable is securely connected and undamaged.

4. Verify that the sensor responds correctly when film is present.

Step 4 – Reinstall B-Film

1. Remove the B-Film completely.

2. Reinstall the film following the standard B-Film installation procedure.

3. Observe the indicator lights during initialization to confirm normal operation.
