Troubleshooting

Cash Drawer Not Opening Automatically

When a cash transaction is fully paid, the cash drawer should open automatically. If it does not, follow the steps below.

1. Check The RJ12 Cable Connection

The cash drawer connects to the register using an RJ12 cable.

  1. Check the cash drawer connection.

    • Locate the RJ12 port on the back of the cash drawer. This is the only port on the cash drawer.
      ​

    • Make sure the RJ12 cable is securely connected.
      ​

  2. Check the register connection.

    • Locate the third port from left to right on the back of the register.
      ​

    • Make sure the RJ12 cable is connected to this port.
      ​

    Important: Do not connect the cash drawer to the Register's Ethernet port. The Ethernet and RJ12 ports can look similar.
    ​

  3. Reconnect the cable.

    • Unplug the RJ12 cable from both the cash drawer and Register.

    • Reconnect both ends securely.

    • If the issue continues, try switching the ends of the RJ12 cable and reconnecting them.
      ​

  4. Complete another cash transaction and check whether the drawer opens automatically.

2. Verify The Cash Drawer Configuration

The cash drawer must be created and assigned to the Register it's connected to.

  1. From the Snackpass Dashboard, go to Settings > Devices.
    ​

  2. Locate the register that the cash drawer is connected to.

  3. Click Edit.
    ​

  4. Scroll down to Cash Drawer Settings.
    ​

  5. From the dropdown menu:

    • Select an existing cash drawer, or

    • Click Create to create a new cash drawer.

  6. Save your changes.

  7. Complete another cash transaction and check whether the drawer opens automatically.

Note: Cash drawer configuration is the same on SnackOS 1.0 and SnackOS 2.0.

Drawer Opens ManuallyBbut Not Automatically

If the drawer opens normally with the physical key but does not open after a completed cash transaction:

  1. Check the RJ12 cable connection.

  2. Confirm the cash drawer is correctly assigned to the Register under Settings > Devices.

  3. Complete another cash transaction.

If the drawer still does not open automatically, contact Snackpass Support.

Drawer Will Not Open Manually

If the drawer does not open using the key, check whether it is locked or jammed.

Check The Lock

The cash drawer is:

  • Locked: Key position is horizontal.

  • Unlocked: Key position is vertical.

If the drawer is locked, turn the key to the vertical position and try opening the drawer again.

Check For A Jam

If the drawer is unlocked but does not open:

  1. Try pulling the drawer gently. Do not force it.

  2. If possible, remove the cash tray.

  3. Check for bills, coins, or other objects blocking the drawer.

  4. Use your hands to carefully remove any visible obstruction.

  5. Try opening the drawer again.

Do not force the drawer open or use excessive pressure.

If the drawer remains stuck, contact Snackpass Support.

Lost Cash Drawer Key

If the cash drawer is locked and the key has been lost, Snackpass does not provide replacement keys. Replacement keys can be ordered directly from Volcora.
​

The key code is printed on the front of the lock and consists of 3–4 digits.
​

You will need this code to place the order. Orders without a key code will be cancelled. Order a replacement cash drawer key

Maintenance Tips

Clean And Lubricate The Drawer Slides

To keep the drawer opening smoothly:

  1. Remove any old grease from the drawer slides using a lint-free cloth.

  2. Apply a very thin layer of lithium-based grease to the slides.

  3. Open and close the drawer several times to distribute the grease evenly.

Inspect The RJ12 Cable

Periodically check the RJ12 cable for:

  • Visible damage

  • Fraying

  • Bent or damaged connectors

  • Loose connections

If the cable is damaged, replace it with a compatible RJ12 cable.
