Using the PX-712UF Self-Test Diagnostics
The PX-712UF contains a set of self-test diagnostics that can help
isolate trouble and determine if a problem is in the drive or elsewhere.
What You’ll Need
To perform the tests you’ll need a blank piece of Plextor-recommended
DVD+R, DVD-R, or CD-R media. (See “Recommended Media” on
page 74, or visit our web site.) The self-test will write to this media, so
you won’t be able to use this disc again.
Performing the Self-Test
This tests three functions of the drive: writing at maximum speed,
continuous playback at maximum speed, and random access.
To perform the CD write/read test:
1. Unplug the USB or FireWire cable from the rear of the Plextor PX-
712UF drive.
CAUTION
: Failure to disconnect the USB or FireWire cable before
starting the test could result in system data loss.
2. Set the PX-712UF drive’s power switch to OFF (so the “0” is
depressed).
3. Slide the SELF TEST switch to the left (ON) position. Use a pen
point, paper clip, or other similar object.
4. While pressing the eject button, set the PX-712UF’s power switch to
ON (the “1” is depressed). The front-panel disc/busy indicator blinks
green and amber, and the disc tray opens.
