How does a bill acceptor work?
Through the use of magnetics and an optically reflective and transmissive sensor array, The GBA scans the currency for authenticity. The currency is then passed and stacked to the cashbox.
How do I clean the GBA and how often should I do it?
Use and environment determine how often the GBA should be cleaned. A general rule is when the acceptance rate drops. Use a 50 % Isopropyl Alcohol and 50% Water solution. To protect the plastic components, do not exceed 50% alcohol. Complete instructions can be found on page 4 of the GBA product manual.
Can I use cleaning cards?
Cleaning cards are found to be ineffective in the GBA and should not be used.
Can I calibrate the GBA and how often should I do it?
Calibration can and should be performed when you change the EPROM or if a drop in acceptance occurs. Calibration is easy to do and uses the white calibration paper found in every GBA operating manual. Complete calibration instructions can be found on page 4 of the GBA operating manual.
Can I use any white sheet of paper to calibrate the GBA?
No, the white calibration paper found in every GBA operating manual is a special optical grade paper designed for the GBA. Standard sheets do not have the optical characteristics necessary to calibrate the GBA sensor array.
How can I upgrade my software?
Software can be shipped or e-mailed from Astrosystems Inc. at the request of the customer. Remember when handling an EPROM always wear an antistatic wristband. The GBA must be calibrated after a software change. Complete details for changing an EPROM can be found on page 4 of the GBA operating manual.
