Subnet Mask

• 255.0.0.0 if the IP address starts with a number less than 128
•

if the IP address starts with a number from 128 through 191
• 255.255.255.0 if the IP address starts with a number greater than 191

Be sure to confirm the subnet mask setting with your network administrator
before proceeding. In some cases the required setting may be different from those
listed.
Gateway
If your TCP/IP network has a gateway, and users outside the gateway print to the
RIP Station using TCP/IP, enter the gateway address. Obtain the correct gateway
address from your network administrator.
IP Auto (Gateway)
—Use this option to get the gateway address automatically for
printing with TCP/IP. This option is available only if you selected DHCP or BOOTP
as the protocol.
If you select the DHCP or BOOTP protocol and later change it to RARP, you must
return to Setup and choose IP Static in the Gateway section, not IP Auto. You can then
set the address manually. This is because RARP does not support automatic
assignment of the gateway address.
IP Static (Gateway)
—This option is available if you selected RARP as the protocol.
Use this option to set the gateway address for printing with TCP/IP. If your network
uses a gateway, you must change the default
127.0.0.1 to a correct gateway address for
your network.
