Scanner is Not Working

Fix a barcode scanner that won’t scan or is not showing products on the POS.

Use this when the barcode scanner doesn’t scan items.

The scanner light doesn’t turn on, barcodes don’t register on the POS, or the scanner beeps but nothing appears on screen.

This is usually a loose cable, a wrong port setting, or the scanner needs to be reprogrammed.

Symptoms

You may see one or more of the following:

• The scanner light doesn’t turn on when scanning.
• The scanner beeps but the item doesn’t appear on the POS screen.
• Barcodes don’t register at all.
• The scanner worked before but stopped after a cable change or POS restart.

Most likely cause: A loose cable, wrong port assignment, or the scanner needs reprogramming.

After every step, scan a barcode to test.

✅ The item appears on the POS screen — stop here. The scanner is working. ❌ Still not scanning — go to the next step.

Before you start

• Identify the scanner model: RubyReady or 2D Scanner.
• Check that the scanner cable is visible and accessible.

How to fix the scanner

1

Check cables and connections

Check connection point:

• Scanner cable
• MSC splitter
• All Points Interface
• POS port

Unplug and reseat each connection firmly.

2

Reprogram the scanner

Go to CSR Functions → Maintenance Menu → Device Configuration → Scanner Configuration

Select RubyReady or 2D Scanner, depending on the model. Reboot the register after saving the setting.

3

Check port assignment and baud rate

Confirm the scanner is assigned to the correct port and the communication settings (baud rate) match the scanner model.

FAQ

How do I know which scanner model I have?

Check the label on the scanner itself. RubyReady and 2D Scanner are the two common types. If you’re unsure, try both options in Scanner Configuration.

What is the MSC splitter?

The MSC splitter is a small box that connects the scanner cable to the POS. Make sure both ends are firmly plugged in.

What is the baud rate and why does it matter?

The baud rate is the speed at which the scanner talks to the POS. If it’s set wrong, the POS won’t understand the scanner’s signal.
