If you see the message "The combination of IP address and subnet mask is
invalid.", try the following solutions:
■
If your router or access point is set to assign IP addresses using DHCP, try
setting the printer's IP address setting to
wireless or page 21 for wired installations.)
■
If you want to manually configure the printer's IP address, click
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 instructions.
■
Set a unique IP address for your printer. All IP addresses are written in
segments of four numerical values. The last segment must be set to a
unique numerical value (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.
For example:
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, if a gateway value is set, use the same value as the IP address for your
wireless router or access point.
The printer does not appear in the Add Printer window (Mac OS X)
Make sure the printer driver was installed correctly and your computer's TCP/IP
settings are configured correctly.
