The printer is a Xerox Phaser 6360DX. It gives the following TCP/IP
details about itself. As far as I know, the printer came with these
settings. Surely they should work with a PC!

Host name: 169.254.164.199
Host name requested: test-13863
IP Address: 169.254.164.199
Network Mask: 255.255.0.0
Router/Gateway: 0.0.0.0
DHCP/BOOTP: Enabled
IP Address Source: Self-assigned
DDNS: Enabled

Any use?

Yes, it says that your printer is expecting to be assigned an IP address by
a DHCP server, and it isn't happening.
Regardless of any other point of working or not, this seems like a problem
straight away.
How do your other machines get addresses? are they assigned manually or are
they using DHCP?

I notice on a previous message you say that the macs are on 10.0.1.x
addresses, so I assume the PC is too. If they are manual, can you not set
the printer to a manual address in a similar range too?

What's a DHCP server?

DHCP = Dynamic Host Configuration Protocol. A DHCP server hands out IP
addresses inside a certain range. Typically, on a home or office DHCP server,
those ranges are set to one of the following:

Class C addresses: 192.168.x.y, where 'x' is 0 to 255, and 'y' is 1 to 254.
The 192.168.x.y group is the Class C private network group. IPs in private
networks are not routed directly over the Internet, they need a gateway for
that. Usually the router upon which the DHCP server is running will be the
gateway. Each Class C private network can have a maximum of 254 devices.
Class C private networks are usually used in homes and in small offices.
Typically Linsys and D-Link routers will come from the factory set to connect
a Class C private network to the Internet by default.

Class B addresses: 172.16.x.y to 172.31.x.y. This is the Class B private
network group. Class B private networks, like Class C private networks,
require a gateway to access the Internet, and again that gateway is usually
the router. Each Class B private network can have up to 65,534 devices. Class
B private networks are often used in large offices, and by ISPs to service
their clients. Some Belkin and Speedtouch systems default to Class B private
network setups.

Class A addresses: 10.x.x.y. This is the Class A private network group. Class
A private networks, like the other two, require a gateway, which again is
usually the router. Each Class A private network can have up to 16,777,214
devices, making it useful for very large offices and major ISPs. For reasons
which no doubt make sense in Cupertino, Apple's routers out of the box are
set for Class A private networks.

All home/office routers can be reset to deliver the private network you want.
DHCP can be turned on or off. Many routers can be set to automatically
control PPPoE and PPPoA connections.

Is that the Airport Extreme?

Unless you have another DHCP server on the network (a Linux box, a OS X
Server or Windows Server box, or a Mac or Windows set to deliver Internet
Sharing) the odds are that your local DHCP server is the router. If your
router is an AirPort, then yes.


All of the Macs are assigned an IP address by the Airport Extreme Base
Station as far as I know. They all seem to be in the range: 10.0.1.xxx.

That would be a typical Apple Class A private network.

Airport itself is 10.0.1.1.

That would be perfectly normal.

The PC says its address is 10.0.1.9.

Again, that would be normal.


From the printer's controls I hit 'renew DHCP lease' and it's IP address
seemed to become 0.0.0.0.

You cleared the DHCP lease info. The printer can't find the DHCP server, so
its IP became 0.0.0.0, which is not routable, and then APIPA kicked in.

No use to anyone I guess. I then hit 'reset
network settings' (or something like that) and it reverted to
169.254.164.199.

Yep, that's APIPA. The printer is not seeing the network. As the network is
visible to other systems, and the DHCP server is running and is visible to
other systems, that means that either the media between the printer and the
DHCP server is bad, or the printer's NIC is bad. If the printer is supposed
to be on wireless, then that means that there's something with the NIC.

Do you have MAC address filtering turned on on the router? Turn it off. Do
you have WPA security on the router? It's possible that the printer's NIC
can't handle WPA. I would recommend using a cable connection rather than
dropping down to WEP or no security. (Actually WEP _is_ no security, but
let's not go there.)


I have no idea if any of this information is at all useful!
