Preventive maintenance

  • Test a transaction after every service.

Expanded guidance

  • Confirm all steps are documented so the next technician can reproduce the results.
  • Capture before/after metrics (errors cleared, sales restored, or uptime improved).
  • Review machine, reader, or route settings to ensure they match location standards.

Common pitfalls

  • Skipping a controlled test leads to false positives.
  • Updating hardware without documenting configuration changes.
  • Forgetting to verify payout, refund, or reconciliation data after changes.

Next-step checklist

  • Run a final test with known-good inputs.
  • Log the outcome with date, time, and device identifiers.
  • Schedule a follow-up check if the location has high traffic or seasonal demand.
