  1. 1

    Inspect the coin acceptor's inlet and internal coin path for any physical obstructions, foreign objects, or debris.

  2. 2

    Verify the power supply voltage to the coin acceptor module against the manufacturer's specified nominal values.

  3. 3

    Check all data and power cabling connections between the coin acceptor and the main control unit for proper seating, damage, or corrosion.

  4. 4

    Perform a functional test by inserting a known good coin to observe if the acceptor registers the transaction or provides any diagnostic feedback.

  5. 5

    Verify system configuration parameters related to the coin acceptor operation (e.g., enable/disable status, coin type recognition) within the main control unit's interface.
