Technical analysis of Fujitsu F53 bill dispenser exhibiting bill tearing due to damaged rollers. Includes diagnostics, solutions, prevention, and safety protocols.
Isopropyl alcohol (90% or higher) is recommended. Ensure it is completely dry before operation.
The lifespan varies based on usage and environmental conditions. Regular inspection is crucial.
Contact Fujitsu directly or authorized Fujitsu distributors for replacement parts.
The Fujitsu F53 utilizes 24V DC motors to drive a series of rollers that transport bills through the dispensing mechanism. Optical sensors detect bill presence and movement. Surface irregularities on the rollers cause uneven friction, leading to stress concentration and tearing of bills, particularly polymer-based bills. Signal attenuation from damaged sensors will cause misreads in the system causing incomplete dispenses.
Observed bill tearing during dispensing. Visual inspection reveals damage to the surface of the bill dispensing rollers.
High voltage (24V DC) is present within the Fujitsu F53 bill dispenser. Always disconnect power and follow Lockout/Tagout (LOTO) procedures before performing any maintenance or inspection. Avoid contact with electrical components. Wear appropriate personal protective equipment (PPE), including safety glasses and gloves.
Implement a regular cleaning schedule for the bill dispenser, including roller surfaces and bill path.,Use only approved bill types and quality.,Periodically inspect rollers for wear and tear.,Ensure proper environmental controls (temperature, humidity) to minimize roller degradation.,Install vandal-resistant features to protect the dispenser from physical damage.
Check the roller alignment using a feeler gauge. Even slight misalignment can cause significant bill tearing. Also, check the torque on the roller motor. Low torque can prevent proper feeding and also cause damage to the bills.
