Installation and Service Guide: Printer Controller EB-34
Replacing Parts
•
If troubleshooting strategies (checking cables and connections, reinstalling system software, and so forth)
do not solve the problem and you suspect either the HDD or the motherboard is faulty, always troubleshoot
in the following order:
•
First, replace the HDD and install system software.
Always replace a faulty HDD with a new HDD. Transferring a HDD from one EB-34 to another is incorrect and
strongly discouraged.
•
If the problem persists, reinstall the original HDD in the system, and then replace the motherboard.
Motherboard cautions
If you have exhausted all other troubleshooting remedies and determined that you need to install a new motherboard,
be sure to observe the following cautions:
•
Transfer the DIMM, CPU, and CPU cooling assembly from the old motherboard onto the new motherboard.
BIOS chips are not interchangeable.
Replacing both in the wrong order, without updating the system, will cause the system to malfunction. For the
correct order, see
•
Do not
reinstall system software at this time.
Reinstalling system software is not necessary when installing a new motherboard and can result in an error if done
before transferring options to the new motherboard (described on
.)
Important:
Troubleshooting in the wrong order will cause the system to malfunction. In general, it is highly
unlikely that both a HDD and the motherboard are defective; therefore, avoid replacing both to solve one
problem.
Caution:
Follow ESD and other safety precautions when handling the motherboard. If you need to
remove the motherboard during service, place it on a grounded, anti-static surface.
Caution:
Do not
transfer the BIOS chip from the old motherboard onto the new motherboard.
Caution:
Do not
replace the HDD and the motherboard at the same time.
