5. Maintenance and Troubleshooting
This section explains maintenance and troubleshooting procedures for
your PX-820 drive.
With proper maintenance, you can prevent problems. If trouble arises,
you can often solve many simple problems on your own, rather than
wait for assistance from a Plextor representative.
Cleaning the PX-820 Drive
Plextor drives are sealed against external contamination, so in a normal
computer environment and with normal use, your drive should not
require internal cleaning. However, if your drive has been in use for
some time and has just recently started to exhibit read/write problems, it
is possible that dust has accumulated on the laser lens. In this case:
•
If your drive is still in warranty and you are experiencing problems,
send the drive to Plextor. (See “Returns” on page 79.)
•
If your drive is out of warranty, before returning the drive for repair
you may want to try a short blast of canned air aimed at the center of
the drive. Use only electronics-grade canned air: sterile, filtered, and
moisture-free. If you notice no improvements after this step, you will
need to return the drive for repair.
CAUTION
: Do not attempt to clean your drive using any solvent-based
cleaners. Also, do not use an air compressor, because the high-pressure
blast can damage the drive.
ANOTHER CAUTION
: Do not use a CD cleaning disc. Cleaning discs
that use a felt pad can scratch the laser lens surface and render the drive
inoperable. Cleaning discs with brushes may also scratch the lens.
Moreover, these cleaning discs are often out of balance, making their
operation very noisy.
