4. Note the position of the jumpers at the rear of the PlexWriter. Write down the
jumper positions. (You’ll need to add test jumpers for the test, but you’ll want to
remove these jumpers after the test and leave the PlexWriter’s setup the way you
found it.)
5. Now install jumpers as follows:
Install one of the spare jumpers across the “TEST” jumper pins.
Install another spare jumper across the “BLOCK SIZE” jumper pins.
If there is a jumper across the “TERM” pins, remove it for this test.
Figure 22: For Self-Test, Add the TEST and BLOCK SIZE Jumpers, and Make
Sure There Is No Jumper Across the TERM Pins
6. If you removed the drive for access to the SCSI cable and mode jumpers, slide it
back into the computer.
7. Replace the computer’s cover.
CAUTION: Turning on the computer power without first replacing the cover can be
dangerous to the computer’s components and also to you. Be aware of the danger of
electric shock and do not touch any components inside the computer.
8. While pressing the stop/eject button on the PlexWriter, turn the computer power
on. The tray ejects, the ON indicator is illuminated, and the WRITE H and
WRITE L indicators blink alternately.
9. Insert a blank Plextor-recommended CD-R disc and press the stop/eject button to
load the 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-approved CD-R disc.
