My Canon DR-9080 scanner is duplicating pages, when it is not set to do that, it is not every page but consistently the 1st page and 15th page. Have uninstalled drivers, re-installed drivers, changed rollers, cleaned - everything I could think of - any advice.

Very likely it is the software that you are using. I would run virus scan like Mohan suggested, and then test again. If the problem is not a virus, then I would uninstall the scanning program and reinstall it...or contact the software manufacturer if you have a maintenance agreement with them. There is a good free downloadable high speed document scanning software available if you want to load it and verify that it is a software problem.

Very strange problem! Do you mean that you consistently get a duplicate image of page 1 & 15 even without scan? There could be some problem in your Computer (Virus/corrupted DLL files) You can also try and fix this problem by running 'SCANDISK' . If this is not working, please try on a different computer.
