Installation and Service Guide: Printer Controller EB-34
Troubleshooting
Network
If you suspect a network problem, keep in mind the following:
•
If the EB-34 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
from the user documentation set.
Unable to connect to
the network, or the
green LED on the
network port is not lit.
Possibly one of the following:
•
Network cable is connected to the
wrong Ethernet 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 EB-34
motherboard is faulty.
1 Make sure that the correct cables are connected to the
correct ports on the EB-34 connector panel. The upper
Ethernet port is for the network straight-through cable;
the lower Ethernet port is for the scan cable (crossover
Ethernet).
2 If the green LED on the (upper) Ethernet network port is
not lit, check the cable connection of the upper Ethernet
network port and the network. Make sure that the cable
is a straight-through cable, not a crossover cable
3 If the network cable is a straight-through cable and not a
crossover cable and is properly connected to the (upper)
Ethernet network port, connect a new network cable to
the (upper) Ethernet network port.
4 If the problem persists, ask the network administrator to
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
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
).
