146 TROUBLESHOOTING THE M204: TCP/IP Problems

• Have you checked your network connection to the M204? Try it at a new location

on your network if possible or swap in another device.

• Have you made an entry in your host table (/etc/hosts, host nis map, or DNS

name table) for the M204?

• Have you tried to ping with the IP address instead of the IP name? This will

eliminate any name-lookup issues and focus more on the communications

between the M204 and your host.

• Is it possible that a duplicate IP address has been assigned?

• Did you use the correct netmask for your particular environment?

• Has the M204 been moved from another network? If so, it needs to be

reconﬁgured to integrate with its new location. This includes a new IP address and

netmask at the minimum. Please see Restoring To Factory Defaults on page 124

and M204 Conﬁguration on page 23 for possible conﬁguration methods.

• Is there a router between the M204 and your host? If so, a default router or a static

route must be conﬁgured on the unit so the Print Server knows how to get its

response back to the originating host. Please see store tcpip on page 110 and

Getting Ready for Complex Networks on page 125.

• Have you set any hosts or networks in the M204’s TCP access list? If so, only

these entries can access the unit. Please see list tcpip on page 88 to view current

entries.

• Do you have a RARP or BOOTP server running on your network? By default, the

M204 comes with the RARP and BOOTP request turned on so although you may

have stored a particular network conﬁguration in the units EEPROM, a RARP or

BOOTP server may supply new network parameters upon bootup. To turn off

RARP and BOOTP on the unit, please see store tcpip on page 110.

If none of these help, try the following:

• Store the network parameters or view the currently stored settings via a terminal

on COM1 or COM2. This logs you into the unit’s command set where you can get

a better understanding of what’s going wrong. Please see Manual Conﬁguration

Through the COM Port on page 28.

• Reset the unit to default settings. Please see Restoring To Factory Defaults on

page 124. Once the unit is in the default state, use one of the conﬁguration options

listed in M204 Conﬁguration on page 23 to reconﬁgure it.
