Diagnostic LED Flash Sequences
When the printer is powered ON, a sequence of self test
diagnostics are run. Some failures that are detected in
these tests are identified by a flashing sequence indicated
on the system controller diagnostic LED located on the
Controller Board at the rear of the printer (see Figure 1.1
on page 1-6).
Table 5.3 identifies the faults associated with the flash
sequences.
