Service Procedures
Hard disk drive
The factory-installed HDD is formatted and loaded with system software, network
drivers, and printer fonts. The HDD is also used to store spooled print jobs. Available
space on the HDD is displayed on the Control Panel.
If you replace the HDD with a new one, you will need to install system software on the
new HDD. (Spare HDDs are shipped without system software installed.)
Do not replace the HDD and the motherboard at the same time. Doing so in the wrong
order, and without updating the system (see page 4-26), will cause the system to not
function.
It is unlikely that both the HDD and the motherboard are defective; therefore, avoid
replacing both to solve one problem. If troubleshooting strategies (checking cables and
connections, and so forth, see page 4-11) do not solve the problem and you suspect
either the HDD or the motherboard are at fault, use the following order to troubleshoot:
replace the HDD, install system software, and then check to see if the problem persists. If
it does, perform other procedures, such as replacing the motherboard (see page 4-26).
Proper handling
Improper handling can damage the HDD. Handle the HDD with extreme care:
• Use proper ESD practices when grounding yourself and the ColorPASS.
• Keep magnets and magnetic-sensitive objects away from the HDD.
• Do not remove the screws on top of the HDD. Loosening these screws voids
the warranty.
• Never drop, jar, bump, or put excessive pressure on the HDD.
• Handle the HDD by its sides and avoid touching the printed circuit board.
• Allow the HDD to reach room temperature before installation.
HDD problems may be caused by the following:
• Loose or faulty connection
• Faulty ribbon cable
• Faulty hard disk drive
Make sure you attach an ESD grounding wrist strap and follow standard ESD
precautions before handling ColorPASS components.
