Figure 4-78. Main PWA LED Operation.
Ensure Main PWA LEDs (light emitting diodes) are properly functioning:
D1 – Normally flashes; DSP is not active. Steady during print operations.
D9 – Normally flashes; Power PC processor is idle. Stops flashing when
processor is active (i.e. during paper sensing operations).
D10 – Normally OFF; Flashes during initialization, then turns off. LED
staying on would indicate a problem when the FPGA is unconfigured.
Ensures the gate array chips have been properly programmed (one on
Main PWA and on each Carriage PWA).
D8 - +24V available.
D13 - +5V available.
