I fixed. Opening the calculator the roller was melted, removed all posible residual and then cut 3 1/2” of electric tape and split about the wide of the roller and roll on the roller in the same way that it move to feed the paper.Casio NR-8TE AND IS WORKING FINE NOW.
I had the same problem. The rubber roller that grabs the paper was sticky, soft, and fragile. It did not turn when the shaft turned. I wish I knew what kind of electrical tape Luis wound onto the shaft to make a usable roller. Even if the part were available, it would be a tough job to install a new roller. Too bad to toss this marvel of microengineering on account of one lousy rubber part.

I don't know this particular calc very well, but on most calcs, the paper feeds between the rubber one and a plastic idler roller that is on a shaft below the rubber one. if you can see the rubber roller turning, check the plastic one as it can sometimes slide to one side or the other, and bind up causing paper to not feed. you can usually get at it with a small screwdriver or something like that and center it back and that will take care of problem.

The rubber roller disintegrated leaving a residue which I cleaned off. I just don't know where to find a suitable replacement as Casio does not provide parts to this machine any longer.
I have the same roller disintegration, were you able to locate a part? chris
I have the black residue on the roller, too. I have to pull the paper up each time I enter anything. No replacement parts? my plastic pressure piece is centered, no probem there.
