Immediately after power-up, all five of the green LEDs should illuminate steadily
for several seconds. Then the USB, LPT1 and LPT2 LEDs should flash ON
simultaneously three times. 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 these three LEDs, followed by a
quiescent state with all three LEDs dark.
If the Self-Test routine traps any component error, then following the LED tests
the Self-Test will halt and the LEDs 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.
When the DP-300U is powered ON , it also automatically performs a Self-Test on
each of its major components. The final result of the Self-Test is signaled by the
state of the USB, LPT1 and LPT2 LED indicators following the Self-Test.
Preliminary to the actual component tests, the three LED indicators are tested to
confirm their steady and flashing operation.
