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. 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. Thanks for reading, bob prohaska
