Indicator Test
Immediately upon power-up, all three indicators will show steady green
for several seconds. Then the LPT indicator will flash three times while
the Pw/Tx and Lk/Rx indicators remain steady. Irregularity of any
indicator during this test indicates that there is a problem with the
indicators themselves. Contact your dealer for correction of any
indicator problems before proceeding.
Circuit Tests
The circuit tests immediately follow the indicator test. 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 circuit tests, testing will halt
with the LPT indicator continuously signaling the particular error
according to the following table.
