      Troubleshoot a Cash Drawer

      Follow these steps to resolve cash drawer malfunction.

      IMPORTANT

      • A cash drawer is linked to the POS terminal through the connected receipt printer.
      • If the connected receipt printer is also not functioning, refer to Troubleshoot a Receipt Printer to resolve the printer issue first, as this is likely to solve your cash drawer issue.
      1. Ensure that the cash drawer cable is securely connected to this port on the receipt printer.
      2. Determine if the cash drawer is physically locked.
        1. Locate the cash drawer key provided with each individual drawer.
          • If needed, purchase a replacement key on our website: parts.getunion.com.
          • If the key is not found on our website, or is not available, please contact Support.
        2. Insert the key into the drawer and turn counterclockwise to open.
          ⇒ Result: If the key turns but the drawer does not open, your cash drawer is likely broken. Order a new cash drawer from our website: parts.getunion.com.
        3. If the cash drawer opens as expected, continue to Step 3.
      3. Perform a test print from the printer the cash drawer is connected through.
        ⇒ Result: If the printer functions correctly, and the cash drawer opens with the key, the APG cord between the printer and cash drawer is faulty. Order a new cash drawer from our website: parts.getunion.com.
