Diagnosing Bill Rejection or Acceptance Failure

Diagnosing Bill Rejection or Acceptance Failure
This process helps determine if the bill validator is rejecting currency due to simple contamination, a physical obstruction, a setting mismatch, or a deeper hardware fault.
- Repeated validator failure after replacement attempt: Escalate to manufacturer support to verify controller compatibility.
- If the validator continues to fail after cleaning and verifying configuration, please contact a qualified technician immediately, as further diagnosis requires specialized tools and expertise.
