I have done this in a similar Polaroid camera (a model 800,) by loading paper negatives one at a time, using a large changing bag. it works fine, and the lens is very sharp.
You need enough room in your changing bag or tent to open the back all the way, which has three parts to it that become ungainly in the dark by feel unless you've worked with it for a while. Getting the film properly centered on the film gate, and keeping it from sliding around while you close the various parts of the back, is also a challenge, but rewarding.
