Mamiya C220f side shutter lever stuck

[Meow7]

Hi all, I have a new to me Mamiya C220f, I was warned of the possible shutter lever getting jammed issue, well of course it has happened and I'm wondering how to fix it. It works fine in multi, and the shutter release lever on the lens will work manually in single, but the side lever will not depress it. How do I un jam-it? I did read take off the side of the camera, but I don't really wan to got there just yet

thanks
