PIXMA MX860 says cover is open when it's closed

[Xecrome]

Hey all,

So I opened up my mx860 to clean out the ink pads the other day, and after I put it back together I found that it can't tell when I have closed the top. I have a constant "cover is open" message on the printer. I looked up the mx860 service guide and they point out the divit on the right back as the SCN open sensor, but I can't figure out how it works. It looks like a divit in the plastic cover that isn't attached to any circuitry, and it barely pokes out the bottom near the motherboard(?) but doesn't touch anything ( I have seen some videos online where it pushes a lever and closes a circuit, doesn't seem to be the case here). Not sure if I just put it together wrong. Any advice would be appreciated!
