FS517 w/C550

[copierpro]

Got a service manual inbound but for now I am on the fly with a c550 we got in used.

Came with the fs517 fin and in service mode all ops work testing solenoids, etc etc no errors.

Had 4 small square brackets - I got two I put on bottom with grounding plates clipped in; then two at top orientation top rear is horizontal and at a bit lower front vertical.

I am missing whatever actuates a sensor - can't see how any of these 4 quare brackets close any senosr anywhere. What am I missing here?

attaches with 2 screws on @ top and 1 @ bottom, both @ front.. there is no "attachement" sensor that I know of, all connectors plugged in? (the regular 1 and the harness ones?) Just a thought!
