Network
If you suspect a network problem, keep in mind the following:
• If the E-42 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-42 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-42 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
.
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
).
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
).
