I've used my enlarger (Beseler 45MX) to project slides onto Type 55 with reasonable success. I'm fairly sure I've also done it to the Fuji variations to get prints, but not as recently. I think I needed to add some filtration to get the "right" colors and used sample gels from Rosco to do that. I'd give you the aperture and times I used for the T55, but they're taped to the enlarger which is four states away now. I think it was f32 for about 5 seconds, but that doesn't help much without knowing the enlarger height and lens. I got the starting point (which was VERY close) from an old Polaroid magazine that I'd borrowed (and, of course, no longer have).
