Diagnosing Clover payment terminal app crashes during polymer bill scanning. Focus: scanner lens, cable integrity, and ESD prevention. Non-invasive solutions.
This information can help identify known bugs or compatibility issues.
This can help narrow down whether there is an issue with the bill itself.
Physical trauma can damage the scanner or its internal components.
The Clover scanner utilizes an optical sensor and image processing software. Voltage fluctuations, electrostatic discharge (ESD), or physical obstructions on the lens can interfere with the scanner's ability to correctly interpret the bill's image. Software bugs or corrupted image processing libraries can also trigger application crashes. Signal attenuation due to cable strain can disrupt data transmission from the scanner to the main processing unit.
Electrostatic discharge (ESD) can damage the Clover device's internal components. Avoid touching the scanner lens or connector pins directly. Ensure hands are grounded before handling the device, especially during dry environments. Ensure power cord is not frayed or damaged. Follow Safe Handling procedures when disconnecting power.
Try using the Clover device's built-in diagnostic tools (if available) to check the scanner's functionality. Accessing this may require a specific key combination or administrative password, which must be obtained through official Clover support channels. If available, examine the system logs for error messages related to the scanner or image processing software.
