Re-install the scanner top cover and GUI, but do not install the screws. Re-connect the power cord, switch on the machine, GP 14. Go to Flag 2. Check for the following voltages at P/J455 on the scanner PWB. • +24V between pins 1 and 2. • +24V between pins 3 and 4. The voltages are good. Y↓N→Check the harness between P/J135 and P/J455. Repair the harness, or install a new harness, PL 14.25 Item 13. Enter the dC330 output code 14-005. The exposure lamp illuminates. Y↓N→WARNING Do not install a fuse of a different type or rating. Installing the wrong type or rating of fuse can cause overheating and a risk of fire. Check the fuse. Refer to, to remove the fuse. The fuse is good. Y↓N→Install a new fuse, PL 14.25 Item 11. Re-install the scanner top cover and GUI, but do not install the screws. Switch on the machine, GP 14. Enter the dC330 output code 14-005. The new fuse fails. Y↓N→The lamp is lit. Y↓N→Go to Flag 1. Check the lamp ribbon harness between P/J456 and P/ J463 for open or short circuits. The lamp ribbon harness is good. Y↓N→Install a new lamp ribbon harness, PL 14.25 Item 10. Install new components in the following order: • Exposure lamp, PL 14.25 Item 9. • Exposure lamp inverter, PL 14.25 Item 12. Perform ADJ 14.1 Optics Cleaning Procedure. Perform ADJ 14.1 Optics Cleaning Procedure. Install new components in the following order: • Exposure lamp, PL 14.25 Item 9 and exposure lamp fuse, PL 14.25 Item 11. • Exposure lamp inverter, PL 14.25 Item 12 and exposure lamp fuse, PL 14.25 Item 11.
