Hyosung ATM Guide Addresses Cash Jams and Sensor Issues

Cash jams rank among the most frequent ATM malfunctions, with causes ranging from physical characteristics of banknotes to internal mechanical wear. When encountering a jam, avoid panic and follow these systematic steps:

• Initial Assessment: Visually locate the jammed note. Determine whether it's fully lodged or partially visible, as this dictates the complexity of removal.
• Power Disconnection: Always disconnect the ATM's power supply before physical intervention to prevent electrical hazards.
• Gentle Extraction: For partially exposed notes, apply symmetrical, gradual pulling pressure. Avoid abrupt movements that might tear the currency.
• Tool Assistance: Deeply lodged notes may require specialized extraction tools designed to grip or suction notes without damaging internal components.
• Currency Inspection: Examine extracted notes for folds, damage, or non-standard dimensions—common contributors to jamming incidents.

ATM sensors function as the device's optical and tactile systems, critical for authenticating currency and monitoring transaction flow. Contamination from dust or debris compromises detection accuracy, potentially causing operational failures.

• Optical Sensors: Analyze color patterns and microprinting for authentication
• Magnetic Sensors: Detect security features embedded in banknotes
• Thickness Sensors: Differentiate denominations through dimensional analysis
• Transport Sensors: Monitor note positioning throughout the transaction cycle

1. Power down the unit and access sensor compartments through maintenance panels
2. Use lint-free cloths lightly moistened with 95% isopropyl alcohol
3. Apply compressed air (maintaining 4-6 inch distance) to dislodge particulate matter
4. Execute gentle wiping motions without applying downward pressure
5. Allow complete evaporation before reassembly and power restoration

• Establish monthly cleaning cycles for high-traffic installations
• Implement currency quality controls to minimize contaminant introduction
• Maintain optimal environmental conditions to reduce dust accumulation
