Diagnostic report for Hantle 1700W bill validator exhibiting "Invalid Denomination" errors. Focus: calibration, environmental factors, and non-invasive solutions.
Obtain and provide specific error codes shown on the device's display or in its logs.
Record the temperature range over a 24-hour period.
Track the frequency of rejection for each denomination accepted by the device.
The Hantle 1700W utilizes optical and inductive sensors to verify denomination. 24V DC logic controls solenoid activation for bill acceptance/rejection. Variations in bill polymer composition affect inductive sensor readings. Ambient temperature impacts component tolerances and calibration parameters.
1. Regular Cleaning: Establish a routine cleaning schedule for the bill validator's external surfaces and accessible bill path components.,2. Environmental Monitoring: Monitor the kiosk's internal temperature and humidity levels. Implement measures to mitigate extreme fluctuations.,3. Firmware Updates: Regularly check for and install any available firmware updates from Hantle.,4. Sensor Calibration: Periodically recalibrate the bill validator's sensors according to the manufacturer's recommendations.
Check the bill transport rollers for wear or slippage. Uneven roller pressure can cause bills to skew, leading to misidentification. Clean rollers with isopropyl alcohol and a lint-free cloth. If worn, replace with manufacturer-approved replacements.
