printer path cover & duplexer wont go back in place

..Is it possible for someone to send me a picture of what it should look like ... Ive turned it so many ways Im lost.

And the only diagrams I find online are cartoon like drawing that are no help.

Anyone? Still out of commision.

Just need to see which direction pictured part clicks into

Please!!
