What should I do if I see the message The combination of IP address and subnet mask is invalid?
Try the following:
- If your router or access point is set to assign IP addresses using DHCP, try setting the printer’s IP address setting to Auto. See Wireless installations or Wired installations for more in information.
- If you want to manually configure the printer’s IP address, click Change when you see the Current IP Address Status screen and enter the IP address and subnet mask.
- Make sure your computer is connected to your wireless router or access point. See your router or access point’s documentation for details.
- Set a unique IP address for your printer. All IP addresses are written in four segments of numerical values. The last segment must be set to a unique number (between 1 and 254). When the router is a set to assign IP addresses using DHCP, set the printer’s IP address to a value that doesn’t conflict with the IP address range assigned by the DHCP server.
IP address of your router or access point: 192.168.1.1
IP address of your printer: 192.168.1.3
For the subnet mask, 255.255.255.0 is normally used for small-scale networks (all devices on your network should use the same subnet mask). Also, when a gateway value is set, use the same value as the IP address for your wireless router or access point.
