## Summary
Troubleshoot hardware issues quickly so your team can restore stable service across POS, kitchen, printing, payment, and fiscal workflows.

## Before you begin
- Identify the exact device or hardware path that is failing
- Confirm whether the issue affects POS, printing, kitchen flow, payment, or fiscal workflow
- Check whether the problem is physical, connectivity-related, assignment-related, or workflow-related
- Make sure you are testing the correct device in the correct operational context

## Steps
1. Identify the affected hardware clearly.
2. Confirm the device has power and is physically ready.
3. Check the network or communication path used by that hardware.
4. Confirm the device is signed in or assigned to the correct business, location, or station.
5. Run the smallest possible controlled test to reproduce the issue.
6. Check whether the problem is local to one device or affects a wider workflow.
7. Escalate internally or to Selio Support if the issue continues after power, connectivity, assignment, and test validation.

## Troubleshooting
- **The team calls every issue a hardware issue:** First separate physical problems from sign-in, routing, or workflow problems.
- **The device looks fine but still fails in service:** Check assignment, sync, and the live operational role, not just the screen.
- **One device problem blocks the whole shift:** Build fallback discipline and identify the real critical path.
- **The team changes too many things at once while troubleshooting:** Make one controlled correction at a time and retest.
