The Complete Maintenance Checklist for Commercial Coin Changers

Commercial coin changers are the revenue backbone of arcades, claw machine shops, laundromats, car washes, and high-traffic public spaces. Even an hour of downtime can mean lost sales, frustrated customers, and extra labor costs.

Why This Checklist Matters

Dirty sensors & blocked coin/bill paths

Uncalibrated hoppers & validators

Loose hardware or neglected remote systems

Sticking to this schedule reduces downtime by up to 70% and preserves your machine's 1-year warranty + lifetime maintenance support.

Daily Maintenance (5–10 Mins Per Machine)

Exterior & Dispensing Area Clean

Wipe acrylic doors, touchscreens, and token/coin outlets with a soft, lint-free cloth. Remove dust, sticky residue, or debris that blocks payout.

Bill & Coin Path Quick Inspection

Clear visible obstructions from bill validators (ITL/ICT) and coin acceptors (NRI G13) to avoid rejections or jams.

Hopper & Payout Test

Run 2–3 test transactions to confirm smooth dispensing from CPI/Japanese hoppers; check for slow or missed tokens.

Payment Module Check

Verify cash, card, Nayax cashless, and scan-to-pay functions work without errors.

Error Code Scan

Check the LCD/touchscreen for fault codes; log issues for faster troubleshooting.

Weekly Maintenance (20–30 Mins Per Machine)

Deep cleaning to preserve validation accuracy and security:

Bill Validator Deep Clean

Use cleaning cards + compressed air on ITL/ICT sensors to maintain bank-grade anti-counterfeit performance.

Coin Channel Calibration

Confirm alignment for standard token sizes (20–26.5mm diameter, 1.7–2.1mm thickness) used in your machines.

Hopper Mechanism Service

Clear dust from the dual hoppers; check for jams and ensure consistent payout speed.

Security & Mounting Check

Tighten locks, 3.0mm lock hooks, reinforced hinges, and wall/ground mounts to prevent tampering.

Remote System Sync

Sync MEDO Checking System, mobile app, or mini-program for real-time accounting and remote status.

🔴 Monthly Maintenance (45–60 Mins Per Machine)

Internal Component Audit

Inspect 1.5mm–2.0mm heavy-duty cabinets, wiring, and communication ports (CCTalk, MDB, pulse) for wear or loose connections.

Capacity & Supply Top-Up

Refill coin hoppers (10,000–30,000 PCS capacity) and bill boxes to reduce staff refills.

Display & Lighting Test

Verify 7” touchscreens, 19” LCDs, and acrylic LED lights function properly for clear customer guidance.

Safety & Compliance Check

Confirm CE, RoHS, UKCA, and PSE certifications are intact; test power surge protection.

Operational Speed Test

Validate fast transaction speed to keep lines moving during peak hours.

Quarterly / Annual Maintenance (1.5–2 Hrs Per Machine)

Full System Calibration

Recalibrate anti-counterfeit sensors, coin validators, and payout accuracy for peak performance.

Wear-Part Replacement

Swap worn locks, sensors, or hopper parts using genuine MAX CHANGERS components.

Firmware & Software Update

Perform remote online updates for animations, protocols, and accounting features.

Factory-Grade Performance Test

Replicate the 7-step pre-ship quality check (assembly → testing → packaging) to match OEM standards.

Maintenance Log Review

Document all services to support warranty claims and plan future upgrades.
