I have a Samsung CLX-6220 Color Laser Printer that gets jammed

My Samsung CLX-6220 jams every time I try to print. It seam to be jamming in the fuser unit but error message says paper jam in rear exit. When I open it up the paper is stuck in fuser unit but I also need to take each sheet out from the entire machine which is 4 pages. Unfortunately I have invested a lot of money in this with all new toners, new fuser unit, and transfer belt - all genuine Samsung parts. I even tried putting in the old fuser unit but it does the same thing leading me to believe that’s not the problem. I have taken it apart but I can visibly see anything broken. That said I’m hoping someone out there can guide me to what’s wrong and what part I need to replace!! FYI - I did fix the solenoid about a year ago.

Please help!!!
