Cash Drawer Not Opening
If the cash drawer is not opening, the issue is usually the physical drawer cable, the printer connection, or the trigger event rather than the drawer itself.
Common causes
- Loose or damaged drawer cable.
- Drawer connected to the receipt printer but the printer is powered off.
- No paper in the printer, preventing the kick signal.
- Drawer trigger only happens on the correct sale flow or tender type.
How to troubleshoot
- Check that the drawer cable is plugged firmly into the correct cash drawer port on the terminal or receipt printer.
- If the drawer is connected to the printer, make sure the printer is switched on and loaded with paper.
- Complete a normal sale in TapaPOS to trigger the drawer and confirm whether it opens on transaction completion.
- If possible, try another compatible drawer or cable to rule out a hardware fault.
- If the drawer still does not open, contact support with details of the terminal and printer setup.
Many drawers depend on the receipt printer to send the open signal, so a printer issue can look like a drawer issue.
What to check next
- Check whether the drawer can be opened manually with the key.
- Confirm the printer assigned at POS is the same printer the drawer is connected to.
- If the drawer opens with one printer but not another, the issue is likely the printer port or cable path.
FAQ
Does the drawer need paper in the printer?
Often yes. Some printer models will not fire the drawer kick reliably if the printer is offline or out of paper.
Can a faulty printer stop the drawer opening?
Yes. If the drawer is connected through the printer, the printer must be powered, connected, and functioning correctly.
When should I log a support call?
Log a support call if the drawer does not open after checking the cabling, printer state, and a normal transaction trigger.
