Power-up and Self-Test

Whenever the DP-301 is powered up, two kinds of testing procedures
follow automatically. The first procedure is just a programmed series of
LED flashes, to confirm proper operation of the three LED indicators. The
second procedure comprises programmed tests of each of the DP-301's
major components. If any fault is found during the component test series,
testing is halted and a continuous pattern of LED flashes signals the nature
of the fault.

LED Test Series

Immediately upon power-up, all three of the LED indicators will show
steady green for several seconds. Then the LPT indicator will flash three
times while Pw/Tx and Link/Rx remain steady. Irregularity of any of the
LEDs during this LED test series indicates that there is a problem with the
LEDs themselves. Contact your dealer for correction of any LED problems
before proceeding.

Component Test Series

The actual component tests immediately follow the LED tests. A normal
(no fault) result is signaled by three flashes of the LPT indicator and the
start of normal print server operation.
If any error condition is found during the component test series, then the
test will halt with the LPT LED continuously signaling the particular error
according to the following table.
