 What have you got to lose, given the state of the printer?

I will try first with a different brand of paper, and less weight, while I try to find the solvent.

 The suggestion of wetting a sheet of paper with your choice of solvent
sounds worth a try, at minimum.
 It isn't necessary to take the rollers out, just access them enough
to squirt solvent on them. One of the long-reach nozzled found on
aerosol brake or carb cleaner will at least help. If you can wipe
them off that'd be better of course.

I might be able to reach the roller with my hand and tissue paper or a brush; I have to pull out the paper drawer, and then push my hand inside.

The idea of a faulty paper sensor didn't cross my mind. I didn't think
they'd be mechanical, but in any case they're worth looking for. A bit
of lint on a photocell could conceivably be the culprit.

Maybe I can get a camera at the end of something long, like a medical endoscope for mechanical work. Should exist, unless it is too expensive.
