During startup, the Fiery ES advances through a standard diagnostic sequence. Each diagnostic code flashes rapidly on the
LED display during this sequence, until the Fiery ES 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 “Table 2: Causes and solutions when printer does not print” on page 54 to determine the troubleshooting actions
that you should take.
