Kodak 800 SERIES service manual Main PWA LED Operation

NovaJet 800 Series Service Manual

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.
