A cash drawer that fails to open halts cash transactions and slows service. Clover cash drawers connect via an RJ-12 cable to the receipt printer, which acts as the open trigger. This guide walks through diagnosing and fixing cash drawer issues.
Step-by-Step Instructions
- Verify the RJ-12 cable is securely plugged into the dedicated cash drawer port on the receipt printer (not the phone jack — they look identical but are different ports).
- Confirm the receipt printer is powered on and connected. The cash drawer opens via a signal from the printer; if the printer is offline, the drawer will not open.
- From the Clover device, open the Register app and process a test cash transaction. Upon completing the transaction, select 'Open Drawer.'
- To manually test the drawer trigger: in the Clover Printer app, select the receipt printer and tap 'Open Cash Drawer.'
- If the drawer still does not open, use the manual key (stored at the bottom of the drawer) to open it and verify it is not mechanically jammed.
- Check the drawer's internal wiring by pulling the drawer fully open and inspecting the RJ-12 cable connection inside.
📌 Important Note: The cash drawer must be compatible with your Clover printer model. Not all third-party drawers work universally. Contact KloverSupport to confirm compatibility before purchasing replacement hardware.
