Frequently Asked Questions

What should I do if a coin validator shows error code CV001 (Coin Rejection)?

Error code CV001 indicates a coin rejection. Verify the coin is a valid currency type, clean the coin and try again, check the coin path for obstructions, recalibrate coin validator sensors, inspect the coin for damage, and check validator coin acceptance settings. If the issue persists, contact component support.

How do I resolve a bill acceptor jam (BA002)?

Error code BA002 means a bill is stuck in the acceptor. Power off the acceptor and clear the bill path, remove any stuck bills carefully, inspect the bill path for damage or misalignment, clean the bill path thoroughly, and check bill path components for wear. Contact support if mechanical repair is needed.

What causes coin validator sensor errors (CV003)?

Coin validator sensor errors can be caused by dirty or blocked sensors, sensor hardware failure, lost calibration, wiring issues, or environmental interference. Clean sensors with appropriate cleaning solution, check sensor wiring, recalibrate sensors, test sensor functionality, and contact support for sensor replacement if hardware failure.

How do I fix a bill acceptor UV sensor error (BA003)?

UV sensor errors typically occur due to dirty or blocked sensors, hardware failure, lost calibration, or wiring issues. Clean the UV sensor, check wiring connections, recalibrate UV sensor sensitivity, test sensor functionality, and contact support for sensor replacement if hardware failure.

What should I do if I see a calibration error (CC001)?

Calibration errors may indicate corrupted calibration data, sensor malfunction during calibration, procedure errors, or environmental interference. Retry the calibration procedure, check sensor functionality, verify calibration environment, check calibration data integrity, and contact support for calibration assistance.

How often should I clean and maintain coin validators and bill acceptors?

Regular maintenance helps prevent errors and ensures optimal component performance. Perform routine cleaning weekly or more frequently in high-traffic environments. Follow manufacturer maintenance schedules, keep sensors calibrated, and document all maintenance activities. Contact the component manufacturer for recommended maintenance schedules.
