TROUBLESHOOTING 117
Network (continued)
System starts up slowly
then displays one or more
DHCP error messages on
the control panel.
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 searches for a nonexistent DHCP
server because DHCP is enabled by
default on the E-42B, but the customer’s
network is not using DHCP
• Ethernet interface on the E-42B
motherboard is faulty
• System software is corrupted
1 If the problem persists, ask the network administrator
to check Network Setup. To configure a static IP address (if
applicable for the customer site, as in a non-DHCP
environment), work with the network administrator as
described on page 22.
2 If the problem persists, ask the network administrator
to check 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
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).
Printing
NOTE: Intermittent print quality and color quality problems are difficult to trace. Before you try to troubleshoot print quality problems,
print a color Test Page to make sure that the copier/printer does not need servicing or adjusting.
Test Page fails to print. The copier/printer is not ready to print.
Make sure that the copier/printer is turned on and ready to
print.
A problem exists with the connection
between the E-42B and the copier/printer.
1 If the problem persists:
• Recycle power on the copier/printer.
• Recycle power on the E-42B by shutting down through the
Functions menu, waiting 10 seconds, and then powering
the E-42B back on.
2 If the problem persists, replace the printer interface cable
and board (see page 48).
3 If the problem persists, you may need to service the copier/
printer.
