If the vending machine accepts cash, it will likely need to be able to dispense change to the customer in the form of coins. In order to dispense change, the machine must first be filled with change. This guide will walk through the steps of loading change correctly into the vending machine. 

There are two ways to load change into the machine, which will be discussed below:

The first and preferred way to load change into the machine is to purchase items just as a customer would using only change. This method also tests to ensure the machine's coils, elevator, and any other part used in operation are working correctly. Issues that would occur during normal operation will likely occur here and can be fixed before a customer experiences them. 

To load change this way, simply select an item, then put coins into the coin slot of the machine until the item is paid for. Once the item vends, it can be restocked into the machine. To make this process faster, the price of an item can be changed to a larger value before loading change to be able to load more coins in per purchase. Be sure to reset the price to its original value after change is loaded if this is the case. For steps on how to change the price of an item, check this page!

To load change into the machine using the coin pre storage method:

1. Log in to the admin login of the machine.
2. 1. Tap the arrow to the left of "Admin Login", then input the password into the box below.
      
      
3. Tap the Payment Settings option.
   
   
4. About halfway down the screen, there is text on the right saying "Coin pre storage" with a "Pre-stored" button to the right of it. Tap that button.
5. 1. A dialogue box saying "Please pre coin" will appear.
      
      
6. Insert change into the machine through the coin slot.
7. 1. DO NOT insert coins directly into the tubes in the coin mechanism.
      
      
8. Once all of the change is loaded (2/3rds of each coin tube accepting change is full), tap the "END" button to save changes. 
9. 1. Tapping the "RESET" button will remove all of the change that was just loaded from the machine's memory. If this button is accidentally pressed, empty out the coins just loaded into the coin mechanism, then follow the above steps again to add the change to the machine.
