Regular cleaning and preventative maintenance is recommended to prolong the life of the bill acceptor and reduce the potential for system downtime.  Additionally, if the bill acceptor is not accepting bills or is rejecting bills (pulling them in and returning them), the bill acceptor may require troubleshooting. See below for more information outlined within each tab.


Maintenance Procedure

Bill Acceptor Status

Frequency of Cleaning:  Monthly

  • Upon opening the X-Changer, inspect the rear of the bill acceptor and check for any abnormal status conditions, as illustrated below in Fig. 1a and Fig. 1b. If no abnormal status conditions exist, proceed to step 2.

Bill Acceptor Magazine

  • Follow the steps to remove the bill magazine and access the bill path, as illustrated on the bill acceptor magazine and above in Fig. 2a and Fig. 2b.

Bill Sensor

  • Verify that bill path is clear of dust and debris (Fig. 3a).  
  • Clean wheels using a laundry card and scrape the debris off of the wheels while rotating.
    • NOTE Do not use any metal objects to scrape the wheels.
  • Using a lint-free cloth and Windex, clean the lens window as needed before sliding bill sensor back into place.
  • With the same cloth, clean the inside of the bill acceptor, belts and platen.
  • Reinsert the sensor tray
