Immediately after power-up, all of the LED’s should show steady
green for several seconds. Then the LPT1, LPT2, and LPT3 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. Contact your dealer for correction of any LED
problems before proceeding.
The actual component tests immediately follow the LED tests. A
normal (no fault) result is signaled by a series of three cycles of
sequential flashing of the 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 LED’s 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.
