Where can I find my printer's IP address?
Press the "WPS/AirPrint" button on the printer's control panel once to print a network configuration report. The TCP/IP section will display the device's current IP address, for example, 192.168.1.45.
Setting up a static IP address
One of the common problems in the operation of network printers is the change IP addresses After rebooting the router. If the address changes, the computer will lose connection with the device, and printing will become impossible until the port is manually reconfigured. To avoid this, it is recommended to assign an address to the printer.
To do this, open a browser and enter the printer's current IP address in the address bar. The SyncThru Web Service interface will open. Go to "Network" -> "TCP/IP" and select "Static" as the address assignment method.
Enter the desired IP address (e.g., 192.168.1.200), subnet mask, and gateway. It's important to select an address outside the router's DHCP pool to avoid conflicts with other devices.
| Parameter | Description | Example of meaning |
|---|---|---|
| IP Address | A unique address on the network | 192.168.1.200 |
| Subnet Mask | Subnet mask | 255.255.255.0 |
