Hp 9050 paper jam error 10.11.07

I am getting a consistent paper jam error code 10.11.07, I have cleared the paper path throughly. One solution is that the Vertical transfer unit sensor may be bad, not sure how to test. This problem seems to apply to tray 4 only!!. When I unplug the lower power supply cord, I can run the system diagnostic with no errors. Any ideas???

Thanks Hobson Beeman

The small spring had come losse, probably like you said because the ripped the jammed paper out. I found it in the bottom of tray 4. Removed the TU sensor assembly and reinstalled the spring!!! It worked the error went away. Also installed new roller kits for all trays. Thanks, you were right on target with the solution.
