Installation and Service Guide: Color Controller E-85A
Troubleshooting
Network
If you suspect a network problem, consider the following:
•
If the E-85A 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.
•
There may be conflicting network settings in Setup and on the customer’s workstation.
•
Inappropriate Setup options may cause printing problems.
•
Missing or incorrectly placed printer description files may cause application-specific printing errors.
For additional information, see
Configuration Guide
, which is part of the user documentation set.
Unable to connect to the
network, or neither LED on
the 10/100/1000Mbps
network connector is lit.
One of the following:
•
Cable is connected to the wrong
Ethernet port. Cable should be
connected to the upper Ethernet
port.
•
Faulty network cable or
connection
•
Faulty network
•
Faulty Ethernet interface on the E-
85A motherboard
1 Make sure that the network cable is the correct type
and is connected to the designated network port on the
back of the E-85A (see
2 Check the cable connection to the network.
3 Replace the cable with a new or tested cable.
4 If the problem persists, request that the site
administrator check Network Setup.
5 If the problem persists, request that the site
administrator check other devices on the network.
If other devices are not functioning, there could be a
problem with the network.
6 If the rest of the network is functioning properly and
the problem persists, replace the motherboard
(see
).
System starts up slowly
(seems to hang) and then
displays one or more DHCP
error messages on the monitor.
One of the following:
•
Normal behavior
System is searching for a
nonexistent DHCP server. DHCP
is enabled by default on the E-85A
but the customer’s network is not
using DHCP.
•
If the customer’s network is using
DHCP:
•
Network cable or connection is
faulty.
•
Network is faulty.
•
Ethernet interface on the E-85A
motherboard is faulty.
1 If the problem persists, request that the site
administrator change the default in E-85A Network
Setup.
2 If neither LED on the 10/100/1000Mbps network
connector is lit on the E-85A connector panel, check
the cable connection to the connector panel and the
network. Make sure that the cable is the correct type.
3 If the network cable is the correct type and is properly
connected to the back of the E-85A, connect a new
network cable to the back of the E-85A.
4 If the problem persists, request that the site
administrator check other devices on the network.
If other devices are not functioning, it could be a
problem with the network.
5 If the rest of the network is functioning properly and
the problem persists, replace the motherboard (see
).
