Inverter PCB or scanning lamp failure.

- Verify that the scanning lamp briefly illuminates when the printer’s power is turned on.

- Verify that the scanning lamp fuse located on the Inverter PCB is not open.
- Check for loose connectors and frayed or pinched wires. Reseat the inverter connector at inverter PCB location CN2 and at scanner PCB location J1202.
- Replace the scanning lamp with a known functioning lamp. If the problem persists, replace the inverter PCB.
