Power ON Self-Test
Every DPR-1061 has been factory-tested to operate properly.
When the DPR-1061 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 USB1, USB2 and LPT 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.
Immediately after power-up, all five of the green LEDs should illuminate steadily for
several seconds. Then the USB1, USB2 and LPT LEDs should light OFF
simultaneously. 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 three times,
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.
