and flashing operation.
Immediately after power-up, all five of the green LEDs should illuminate steadily
for several seconds. Then the LPT1, LPT2 and USB LED indicators should light
OFF. Irregularity of any of the three LEDs during these LED tests may mean there
is a problem with the LEDs themselves.
The actual component tests immediately follow the LED tests. A normal (no fault)
result is signaled by a simultaneous flashing of the LPT/USB LED three times,
followed by a quiescent state with the LPT/USB LED dark.
If the Self-Test routine traps any component error, then following the LED tests the
Self-Test will halt and the LPT/USB LED will continuously signal the error
according to the following table. In the event of any such error signal, contact your
dealer for correction of the faulty unit.
