Re: Kodak 8500 giving problems on printing
In thinking more about your problem, I thought of one thing that it could be. There is an optical sensor that looks at the color of the ribbon patch to get the color patches aligned correctly. It's possible that the sensor is dirty and isn't reading the colors correctly. This would cause the printer to "stage" the paper, but not start printing because it can't find the correct ribbon color patch.
Unfortunately, I don't have an 8500 in front of me (I'm at home), but I'll try to explain how to find the emitter and detector. If you open the top cover, near the printhead, you'll see the emitter. As I recall, there's a little plastic cover with a hole for the emitter to "shine" through. The detector is located in the curved plastic part that the ribbon carrier fits into. It aligns with the emitter, os if you find the emitter, the detector will be aligned with it (left/right direction).
Take a cotton swab (Q-Tip) dampened with water, and clean the surface of the emitter and detector. If this doesn't fix it, you'll likely have to send the printer in for repair.
