I had the same issue so I have been putting this camera away for years. I just tried again, and this time I actually fixed it! Omg!! What I did was:
# I only put in the blue paper, and while the camera is making the printing noise, I opened the door and helped it push out the blue paper.
# Then I only loaded 1 photo paper, and it printed!! (I only put in 1 because I thought I’ll need to help it push again.)
# Then I loaded another piece of paper to see if it will work again - it did!
# I haven’t tried to load the entire pack of 10 papers yet. When I do, i can update here : )
