Sunmi Printer Troubleshooting Guide

Step 1: Check the basic connection

1. Turn the printer off and back on.

   • Make sure it is connected to the network and working properly.

3. Check the printer :

   • Verify that the blue light on the printer indicator is on.

     

   • Press the button on the back of the printer twice. On the printed receipt, make sure the printer has an assigned IP address .

   • If you don't have an IP address, follow the instructions in this initial setup guide to reconnect your printer to the network.

     
     

Step 2: Check your settings in Chrome

Step 3: Review the settings in FireMenu

1. Open the FireMenu application.

2. Go to the Settings section → Printing tab.

3. Verify that the FireMenu Print Server is configured correctly:

   • Check that the type ( Ethernet ) and IP address match the current values.

Step 4: Configure a static IP address

If you notice that your printer's IP address changes periodically, you can assign it a static IP address to avoid future problems.

1. Print the printer status ticket by pressing the rear button twice.

2. Open a browser on your Sunmi device and type the printer's current IP address into the address bar.

3. Access the printer configuration page :

   • Click Log in (the default password is empty, leave the password field blank).

4. Go to the Ethernet section.

5. In the IP Address (Static) field:

   • Enter the same address as listed in IP Address (DHCP) , but change the last number to something between 150 and 250. For example, if your DHCP address is 192.168.1.100, you can use 192.168.1.200 as static.

   • Save this new IP address.

6. In the Netmask (Static) field:

   • Enter the same value as shown in Netmask (DHCP) .

7. Click Save .

   

8. Turn the printer off and back on.

9. Follow steps 3 and 4 of the initial setup guide (specify the new static IP address configured).
