Finder prints come undone from the bed

Hey all,

I have a Finder from a couple years back that I'm getting back into using after not printing in general. I've been trying to print some items and part of the print doesn't stick to the bed, and ends up coming undone. I've attached a photo for reference. Any ideas on how to fix this?

Thank you
