Step-by-Step Troubleshooting

Clean the bill validator sensor path with a bill validator cleaning card — run the card through the acceptor 3-4 times to remove dust, ink residue, and debris
Check the MDB harness connection between the validator and the VMC — disconnect and reconnect the 6-pin MDB connector to ensure proper contact
