Chapter 3 Troubleshooting Procedures
5. Observe ribbon movement at both left and right ribbon posts as the metal
end strip crosses each ribbon post.
If the metal strip moves past either post without reversing the
direction of the ribbon, power down the printer. Remove the paper
path or pedestal top cover. Reseat connectors P106/LRP and P107/
RRP on the CMX controller board.
6. While shorting across each ribbon post with the ribbon metal strip or a
screwdriver, check for continuity in connector P106/LRP pins 10 and 12,
and connector P107/RRP pins 14 and 16. (Refer to the Main Wire
Harness Test Tables in Appendix A.)
Replace a ribbon post that fails the continuity test.
7. Check the platen gap.
Adjust the platen gap.
