Sharp UX-B800SE - Manual (Page 18)

Connecting the Machine
16
If the machine is unable to
communicate...
♦
Check the Ethernet cable. Are the
connections secure? Are you using
straight-through (not crossover) cable
for 10Base-T/100Base-TX?
♦
There may be a problem in the router
or other device to which the machine
is connected. Try removing and then
restoring the power to the router (see
the manual for the router).
♦
If [IP ADDRESS/DHCP: FAIL]
appears, remove and then reinsert
the Ethernet cable plug, and repeat
Steps 1 to 3 above. If the same
message appears, check the device
that acts as the DHCP server on your
network (try removing and restoring
the power). If your router is your
DHCP server, make sure that DHCP
is enabled in the router settings. If
your network does not have a DHCP
server, set a static IP address as
explained on page 23.
♦
If a static IP address has been set,
make sure that the network settings
(page 23) are correct .
