PlexWriter 48/24/48U Installation and Users Manual
Using the Self-Test Diagnostics
The PlexWriter contains a set of self-test diagnostics that can help isolate trouble and
determine if a problem is in the PlexWriter drive or elsewhere.
The self-test consists of a CD write/read test.
What You’ll Need
To perform the self-tests you’ll need a blank piece of Plextor-certified CD-R media.
(See “Recommended Media” on page 23, or visit our web site.) The self-test will
write to this media, so you won’t be able to use this disc again.
CD Write/Read Test
This tests three functions of the drive: write, random access, and verify.
To perform the CD write/read test:
1. Unplug the USB cable from the rear of the PlexWriter.
2. Set the PlexWriter’s power switch to OFF (so the “0” is depressed).
3. Slide the SELF-TEST switch cover to the right to expose the self-test switch.
4. Set the self-test switch to the up (ON) position. Use a pen point, paper clip, or
other similar object.
5. While pressing the eject button, set the PlexWriter’s power switch to ON (the “1”
is depressed). The front-panel LED indicator blinks green and amber.
6. Insert a blank Plextor-certified CD-R disc. Be sure to use only CD-R media of
the type recommended by Plextor.
??
If the DISC indicator blinks amber three times, the loaded disc is not a blank
CD-R disc. Remove the disc and insert a blank, Plextor-certified CD-R disc.
7. The drive begins the diagnostic routine. Upon completion of the diagnostic, you
see the results:
??
If there was no problem, the disc is ejected automatically.
??
If there was a problem, the disc is not ejected, and you see the LED indicator
blink green. One green blink indicates a write or read error. Two green
blinks indicate an initialization error.
8. If the disc was not ejected automatically, press the eject button to eject the disc.
9. Turn OFF the PlexWriter power switch and set the self-test switch to the down
(OFF) position..
