Technical cleaning guide for Magner 150 bill validators. Includes safe handling, approved solutions, and diagnostic tips for optimal performance in kiosks.
Use isopropyl alcohol (90% or higher) applied sparingly with a lint-free swab.
At least bi-weekly or weekly if bill acceptance errors increase.
Weak or inconsistent bill stacking, or failure to complete the validation sequence.
The Magner 150 relies on optical sensors and a mechanical transport system to validate and stack bills. Dust, debris, and residue accumulation on sensors or rollers impede performance. Supply voltage to solenoids (typically 24V DC) may be affected by accumulated contaminants, leading to weak actuator response.
Reported issue is maintenance related, indicating potential jams, misreads, or slow operation. Requires detailed cleaning of internal components.
The Magner 150 operates with 24V DC, which poses a shock hazard if improperly handled. Always disconnect the power supply before performing any maintenance. Compressed air can propel debris at high speeds, potentially causing eye injury. Wear appropriate eye protection. Isopropyl alcohol is flammable; use in a well-ventilated area and avoid open flames or sparks. Observe Lockout/Tagout (LOTO) procedures during all maintenance activities.
Implement a regular cleaning schedule based on usage and environmental conditions. Inspect and clean the Magner 150 at least monthly. Use only approved cleaning solutions as specified in the operator's manual. Avoid using excessive amounts of cleaning fluid, which can damage sensitive components. Ensure adequate ventilation to prevent dust accumulation within the kiosk enclosure.
Use a small inspection mirror and a bright LED flashlight to visually inspect the optical sensors for contamination. Sensor malfunction is a common cause of bill rejection. Very fine debris can sometimes be removed from rollers by running a clean sheet of paper through the validator multiple times.
