TROUBLESHOOTING 116
Network
If you suspect a network problem, keep in mind the following:
• If the E-42B does not appear in the list of printers on the network, another device on the network may have been assigned 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, which is part of the user documentation set.
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
• If the E-42B requires a static IP address
(for example, in a non-DHCP network
environment), it may need to
be reconfigured. A static IP address is
deleted when system software is
reinstalled.
• System software is corrupted
• Network interface on the
E-42B motherboard is faulty
1 If the problem persists, have the network administrator
check Network Setup. To configure a static IP address (if
applicable for the customer site), work with the network
administrator as described on page 22.
2 If the problem persists, make sure that the network
administrator has checked other devices on the network.
If other devices are not functioning, the problem may be
with the network.
3 If the problem persists, restore the backup, or reinstall the
system software (see page 89).
Corrupt system software may cause the system to hang.
4 If the rest of the network is functioning properly and the
problem persists, replace the motherboard (see page 59).
