■ LED diagnostic codes
During startup, the imagePRESS Server advances through a standard diagnostic sequence.
Each diagnostic code flashes rapidly on the LED display during this sequence, until the imagePRESS Server reaches Idle.
At Idle, the LED display shows the 00 code.
If the LED display hangs on a code other than 00, one or more diagnostic tests may have failed. Look up the diagnostic code in
“If the printer does not print” on page 79 to determine the troubleshooting actions that you should take.
