What does this error mean?

Does my unit detect counterfeit notes?

The Cassida 5520 is designed to detect and flag any suspected counterfeit notes. This unit utilizes Ultraviolet (UV), Infrared (IR), and Magnetic (MG) (MG only available on certain model) counterfeit detection methods.

What could cause false counterfeit detection?

There are a few reasons that a detector may flag genuine currency as suspect. If bills are worn, bent, torn, or crumpled, the anti-counterfeit features needed to verify a bill as genuine may be compromised. For example, the magnetic ink on a note may wear over time or heavy use, reducing the magnetic response to below detection thresholds. If the 5520 cannot verify the correct features expected on a note, the unit will flag that currency as ‘SUSPECT’. If sensors are dirty or damaged, the 5520 will not be able to detect the necessary anti-counterfeit features needed to verify currency as genuine. Another possible reason is that the detection sensors may be incorrectly calibrated, lost reference, or be under operating conditions that cause false positives. In order to reduce these error types, it is advised to operate the unit out of direct sunlight and reduce interference that may cause sensor errors. If this occurs frequently under normal operation, please contact Cassida Technical Support for troubleshooting or service.

Why is my unit counting notes incorrectly?

One of the most common reasons for miscounting is improper bill loading. In most cases the 5520 will display an error message. For description and resolution of the error, please see the 5520 User Manual, or find the previous question that discusses error messages. The second most common reason of miscounting is poor maintenance of the unit. Eash sensor needs to be cleaned and free of any debris to operate correctly. Due to the complexity of the sensing mechanisms, the unit must be able to sense all features which are expected on genuine currency. SUSPECT errors and wrong denomination errors may occur if sensors are obscured. In rare cases, electromechanical failure of the unit will cause all notes to be sensed incorrectly. For frequesnt, repeatable improper denomination errors, please contact Cassida Technical Support for repair.
