Maintenance
With the exception of periodic cleaning or lamp replacement, the
scanner is virtually maintenance-free. Please read the following
section to learn how to properly maintain the scanner.
Static Electricity Precautions
Static electricity is a constant danger to computer systems. The
charge that can build up in your body may be strong enough to
damage electronic components on the scanner’s printed circuit
board or the computer’s interface card. Therefore, it is important to
observe basic precautions whenever handling electronic
components for your computer. Although areas with high humidity
are much less prone to static electricity, it is best to always take
precautions against accidental damage that can result in expensive
repairs.
The following measures should generally be enough to protect your
equipment from static discharge.
•
Discharge any static electricity that may have built-up in your
body by touching a grounded or anti-static surface. For
example, touch some large metal object or the silver-toned
expansion slot covers at the rear of your computer’s case. Be
sure to do this immediately before removing any components
from their anti-static bags.
•
When handling any electronic components, be sure to carefully
avoid touching any metal part of the component. Avoid
touching any of the gold “fingers” that plug into the expansion
slot. It is best to handle system components either by their
edges or by the mounting bracket which attaches to the slot
opening in the rear of the case.
Follow the above to the best of your ability. Excessive caution is
not necessary, simply take reasonable care.
