Network
If you suspect a network problem, keep in mind the following:
• If the E-8100 does not appear in the list of printers on the network, there may be another device on the network with the same Ethernet
hardware address.
• Conflicting network settings may have been configured in Setup and on the customer’s workstation.
• Printing problems may be caused by inappropriate Setup options.
• Application-specific printing errors may be caused by missing or incorrectly placed printer description files.
• System software may be corrupted.
For additional information, see
Configuration and Setup
on the User Documentation CD.
Unable to connect to
the network, or the green
LED on the RJ-45
network port is
not lit.
Possibly one of the following:
• Network cable is connected to
the wrong RJ-45 port.
• No cable/wrong type of cable is
connected to the network port.
• Network cable or connection
is faulty.
• Network is faulty.
• System software is corrupted.
• Network interface on the
E-8100 motherboard is faulty.
1. Make sure that the correct cables are connected to the
correct ports on the E-8100 back panel. The upper RJ-45
port is the copier interface; the lower RJ-45 port is the
network interface.
2. If the green LED on the (lower) RJ-45 network port is
not lit, check the cable connection of the lower RJ-45
network port and the network. Make sure that the cable is a
straight-through cable, not a crossover cable. (see
3. If the network cable is a straight-through cable and not a
crossover cable and is properly connected to the (lower)
RJ-45 network port, connect a new network cable to the
(lower) RJ-45 network port.
4. If the problem persists, have the network administrator
check Network Setup.
5. If the problem persists, make sure that the network
administrator has checked other devices on the network.
If other devices are not functioning, there could be a
problem with the network.
6. If the problem persists, reinstall the system software (see
Corrupt system software may cause the system to hang.
7. If the rest of the network is functioning properly and the
problem persists, replace the motherboard (see
).
