Fukuda CardioMax FX-3010 ECG Paper Sensor Board Assembly PCB-6381D-C1 Used in Good Working with 90 Days Warranty

Fukuda CardioMax FX-3010 ECG Paper sensor board assembly PCB-6381D-C1 spare part

►Brief Description

The PCB-6381D-C1 paper sensor board assembly is the core sensor module inside the Fukuda CardioMax FX-3010 ECG machine, used to detect and monitor the status of thermal printing paper. It's not a separate circuit board, but a complete assembly integrating optical sensors, mechanical structures, and connectors. Its primary function is to ensure that ECG waveforms are printed accurately and stably on the recording paper. When a new roll of recording paper is loaded, the sensor board needs to detect its presence immediately. This is typically achieved using a microswitch or photoelectric circuit breaker. When the paper roll is correctly inserted, it triggers the switch or blocks the light beam, sending a "paper present" signal to the main board. During printing, the sensor continuously monitors the remaining paper level. When the paper is about to run out, the sensor detects the change in status and immediately sends a "paper out" warning to the system. This allows the device to issue early warnings, preventing recording interruptions due to paper shortages at critical moments.

►Specifications

►Working Principle:

This assembly is typically based on photoelectric sensing technology. The board contains an infrared emitter and a receiver. When paper is present, the infrared light is reflected back to the receiver (or directly blocked by the paper), generating a "high level" or "low level" signal. When there is no paper, the reflected light disappears, and the signal state reverses. This electrical signal is transmitted to the main board via cable, where the main control system interprets it and responds accordingly.

►Common Faults and Maintenance

As a component combining mechanical and electronic elements, the PCB-6381D-C1 may also malfunction. Common symptoms include:

1. False "Paper Out" Report: Even though there is paper, the device keeps indicating a paper shortage.

2. Unable to Detect Paper Shortage: After the paper runs out, the device does not respond and continues to print "dry."

3. Inaccurate Printing Position: Due to an incorrect sensor reference, the waveform is printed in the wrong area of ​​the paper.

►Common Causes and Maintenance Suggestions:

1. Dust/Dirt Contamination: This is the most common cause. Paper scraps and dust accumulate on the window of the photoelectric sensor, obstructing light transmission. Regularly cleaning the sensor area gently with anhydrous alcohol and cotton swabs is an effective preventative measure.

2. Mechanical Displacement or Damage: The sensor bracket may bend or loosen due to prolonged use or accidental impact, leading to inaccurate detection position.

3. Aging of Electronic Components: Aging of the infrared emitting/receiving tubes leads to decreased sensitivity.

4. Connection cable issues: The ribbon cable connecting this assembly to the motherboard may be loose, worn, or broken.
