Ricoh MP C2050, suddenly disappeared from the network

[steele]

Hi, MP C2050 worked fine until suddenly stopped printing. Evertything seems to work fine except that it is not visible on LAN. Machine doesn't obtain IP from DHCP but it's possible to set it manually. Direct connection to the network computer card also checked. Two LEDs in ethernet port are lit. I cleared NCS settings - no effect.

Ping the copiers IP address without networkcable attached, to see if there is another unit using the same Ip (common mistake)

Disconnect the network cable from the MP C2050 and connect it to your laptop. If you do not get a connection with the laptop, then it is either the connector cable or the network, bad jack, bad cabling to the jack or bad switch. If the customer IT does not feel it is their network, ask them if they have another printer that they know is working that can be moved to there to test the connection.

Had one do this a month or so ago, reseated connectors, wound up swapping controllers, new (previously enjoyed) one failed, reinstalled old controller, started working. WTF

Machine doesn't respond even to own "ping"...

Print off a confrig page. If "Ethernet authentication for IEEE802x" is active, it's locking the NIC out. Disable that and all should be spiffing.

Disable SSDP protocol.

I have had the same problem and this post gave me the solution.
It was something beyond my knowledge...Thanks again, keep up the real good job, TM...

is the machine obtaining it's IP address or not?

I have had instances where SNMP caused non-printing issues...disabled SNMP and everything was hunky-dory after that!
