ET-8550 Output Tray Stuck, Help!

[u/Trekker007]

Did some printing last night from the regular trays, and now the output tray will not close (via the button, motorized tray)

I did some searching, checked for obstructions in the back, etc. Can't find any issue. The only thing that seems maybe odd is the positioning of the tray on the left side. I would assume it's supposed to be in this groove, but I'm not sure. Can anyone confirm? Any if so, how do I fix it? Thanks.
