Disconnect connector P106 from the controller board. Test connector P106/CCF for shorts or opens. (Refer to the Main Wire Harness Test Tables in Chapter 3.) Replace components that fail test. 4. Make sure P106/CCF has a good connection at J106 on the controller board. 5. Inspect for obstructions of airways and vents. 6. Check the shuttle for electrical shorts (page 252). 7.

After replacing the controller board, DO NOT make the printer READY, but proceed immediately to the next step. 12. Download and install the latest code from IBM First (page 231). 75
