Installation and Service Guide: Printer Controller EB-34
Replacing Parts
•
If the new motherboard solves the problem that you are troubleshooting, use the motherboard replacement dongle
to transfer options to the new motherboard.
If you determine while in Service Mode that the problem you are troubleshooting was not fixed by installing a new
motherboard, do not expend the motherboard replacement dongle to transfer options to the new motherboard
(described below), do not install system software, and do not replace the hard disk drive. Reinstall the old
motherboard and return the new motherboard and the unused motherboard replacement dongle to inventory. You
may then perform additional service and troubleshooting procedures.
Transferring options (for example, FACI Enablement) expends the motherboard replacement dongle. For details,
Entering Service Mode
Use the following procedure to verify that the system functions properly after installing a new motherboard.
To enter Service Mode and verify the system
Note:
This procedure assumes that the EB-34 is powered off, no media is in the DVD drive, you have installed a new
motherboard, and that you have reassembled the EB-34 and attached external cables.
1
Make sure the EB-34 is connected to the copier.
2
Locate the motherboard replacement dongle provided with the new motherboard and connect it to a USB port.
3
Remove all USB devices (except for the keyboard and mouse) that may be currently connected to any other USB
port.
Reconnect other dongles and USB devices only after you verify that the EB-34 starts up successfully in Service
Mode.
4
Power on the EB-34 and allow it to boot without interruption.
At this point the EB-34 is in Service Mode, so you can verify that the new motherboard solves the problem that you
are trying to troubleshoot. Service Mode is not indicated on the monitor or on the EB-34 control panel.
5
Print the EB-34 Test Page from the copier touch panel (see
6
Ask the network administrator to connect the EB-34 to the network and download a print job over the network
(see
Configuration and Setup
, which is part of the user documentation set).
If the problem that you are troubleshooting persists, or if you are unable to perform
through
above while
in Service Mode, you may conclude that the old motherboard was not the source of the problem and does not need to
be replaced. If so, do not transfer options to the new motherboard (described on
), do not install system
software, and do not replace the hard disk drive. Reinstall the old motherboard and return the new motherboard with
the unexpended motherboard replacement dongle to inventory. For more information about troubleshooting system
problems, see
.
Important:
Do not
transfer options to the new motherboard prematurely. Do so only after you verify the new
motherboard in Service Mode. Remember that once options are transferred to the new motherboard using the
motherboard replacement dongle, the motherboard is customized and cannot be used in another system.
