4.1. Bill Validator (MFLV-9013, MFLV-2110) 
 
Two methods exist for cleaning the bill validator. The first is using a special bill validator cleaning card 
and the second is by manually cleaning the sensors and internal surfaces of the bill validator. 
 
Method 1: 
 
A set of cleaning cards may be used to perform level 1 cleaning without the need of dismantling the 
unit. The cleaning card acceptance mode can be activated either via switch No. 8 on the back of the 
unit, or via the host interface. For more information on how to enable maintenance mode via the host 
machine, please refer to the host machine manual. To enable the cleaning mode via switch No. 8 you 
may follow these steps: 
1) Unplug the power form the unit 
2) Remove the validating head from the housing 
3) Slide switch No. 8 to the OFF position as follows: 
 
 
 
 
 
 
4) Replace the validating head and power cord 
5) The unit is now in maintenance mode and will not accept the cleaning cards once enabled 
6) Follow the instructions on the cleaning card to clean the unit 
7) Once the cleaning was completed you may follow steps 1 to 5 in reverse order by bringing switch 
No. 8 into the ON position. 
Method 2: 
 
When manually cleaning the bill validating head, the following steps must be followed: 
 
First, remove the Bill Validator from the Bill-to-Bill™ 300XE unit by depressing the latch under the Bill 
Validator Head and puling it out. 
 
 
 
 
 
 
 
 
 
After the bill validator has been removed, open the lower and upper compartments.
