If necessary, the bill validator lower housing can be removed using the following procedures. The lower
housing is the portion of the Bill Validator that sits just below the stacker and behind the bill mouth. The
bill mouth is the part of the bill validator that is used to pull in and analyze the bills that have been
inserted. Bills are pulled in by a system that draws them up into the main body. Once they have been
pulled in, four photo-optic sensors are used to scan them and send the information to the electronics.
Perform the following steps to remove the Mars Bill Validator lower housing.
1. Remove the Bill stacker. (See Removing the Bill Stacker)
2. Reach under the bottom of the validator and locate a silver rod in the area below where the
status LED is located.
3. Using your thumb, push the silver rod up toward status flash code LED.
4. Firmly grasp the top of the housing with your fingers and pull the lower housing toward the
palm of you hand. (Be sure to keep steady pressure on the housing at all times during
removal.)
5. Slide the inner housing out of the back of the validator, revealing the belts, pulleys and
sensors.
