Maintenance
The CD-Writer Plus drive requires no maintenance or cleaning. If you
simply keep your CDs clean, you will prevent most problems.
CAUTION: DO NOT use the CD-ROM cleaning CDs that rely on a small brush
to sweep dirt off the laser. DO NOT use high-pressure air to clean the inside of
the drive. These cleaning techniques will damage the CD-Writer Plus drive.
