Coin Mechanism Not Accepting Coins

Coin Mechanism Not Accepting Coins
This procedure diagnoses coin acceptance failures by checking for physical blockages, the condition of the coin path, compatibility of the mechanism, and communication with the main controller.
- If the coin mechanism fails to accept coins after clearing visible obstructions, the electrical communication or the mechanism itself needs inspection by a qualified technician.
- If the issue persists after checking physical paths, a qualified technician must assess the coin mechanism's electrical interface.
