When setting the IP address (IPv4)
NOTE
If you changed the IP address after installing the printer driver
When you use MFNP Port, the port does not have to be changed because a new IP address is detected automatically
when the printer and computer are on the same subnet.
When you use Standard TCP/IP Port, the port to be used with the printer driver should be changed.
"Configuring and Changing the Port"
If you do not know which port you are using, see " Basic Operations/Various Information for Windows ."
When using DHCP, BOOTP, or RARP
You can select DHCP, BOOTP, or RARP.
After the printer restarts, the values obtained from DHCP, BOOTP, and RARP are displayed.
(If the values have been specified previously, they overwrite the obtained ones.)
Because it takes two minutes to check whether DHCP, BOOTP, and RARP are available, we recommend that you
set [Select Protocol] to [Off] for the unused protocols.
When using DHCP
When you use Standard TCP/IP Port, if you cycle the power of the printer, you may not be able to print. This is because
a different IP address from the one that was used is assigned.
To use DHCP, use MFNP Port ( " Configuring and Changing the Port ") or consult your network administrator and specify
either of the following settings.
Specifying the DNS Dynamic Update function
Specifying the settings so that the same IP address is always assigned when the printer starts
IP address obtained with DHCP, BOOTP, or RARP
Specifying the IP address takes priority even when [Auto IP] is set to [On].
When setting the IP address (IPv6)
IMPORTANT
About IPv6
You cannot use IPv6 alone without using IPv4.
IPsec (Security Architecture for Internet Protocol) encryption is not supported.
NOTE
If you changed the IP address after installing the printer driver
Specify the port to be used again in the printer driver.
"Configuring and Changing the Port"
About IPv6 addresses
This printer can have up to nine of the following IPv6 addresses. (You can only register one address manually.) You can
use multiple IPv6 addresses for IPv6 communication.
Type Registrable Number Outline
Link-Local Address 1
The link-local address is specified automatically using the
prefix (information indicating the network to which it belongs)
"fe80::" and an interface identifier generated from the MAC
address of the printer.
Because the address is valid only within the same prefix, it
cannot traverse the router. One link-local address is specified
for this printer whenever IPv6 is being used.
