Bill Validators require preventive maintenance to keep them performing properly. The bill path can become contaminated from dirty bills, dust, moisture, or other foreign matter. It is recommended to clean your validators periodically, depending on the amount of use or the type of environmental exposure. Magnetic-sensing Bill Validators need to be cleaned more often than non-magnetic. Use a soft cloth moistened with mild non-abrasive detergent to accomplish this task. NEVER use alcohol, benzene, or paint thinner to clean the bill carrier belts.
Always refer to the label on the back of the validator for further cleaning instructions.
