Aficio 1060 (B064) curl & jam on full bleed copy

[breaker]

OK, my original was tried on another 1060 and it copied fine on that machine! I think I will start with gears...

It sounds like the fuser unit is okay, and you may have some fuser drive issues instead.

I don't think I've ever come across any of the fuser stepper motor drive problems, but there are obviously drive & coupling gears on the entire slideout assembly.

The sensitivity issues you're experiencing with the fuser carriage reinstallation back into the machine does say something; yes, it could be related but also something coincidental.

One time I did have an issue with the carriage assembly not being able to come out easily. There was some tweaked frame problems on the carriage and I think the machine frame was a little bent from customers slamming the hell out of the assembly.

I would recheck all frame areas for bent alignment pins and warped catches at the front and the machine frame where it catches as well. It could only be off a tiny bit, but it could be enough to cause your problem.
