Epson CX5400 HELP

I didn't find this web-site until after I took my printer apart. I took the Grey arm off of the printer thinking it would be like my old stylus from a number of years ago and I have a problem. When I took the little holder off there is a little spring coil thing in there and when the arm came off it just fell. I did not know it was in there and do not know how to put it back. Is there a manual to show how it goes behind the envelope/paper lever?

I cleaned out all of the print lines and even the disposal excess cushions a little. But it sounds like it just jumps and the print heads do not travel back to their original alignment.

I am pretty positive that it is off track. How do I get it back on track. Is there a manual that shows the epson CX5400 taken apart?
