Canon c7260 E280-0102, E302-0101 and jam 0094

Hello, I have a problem with the dadf, there are days that the printer does not recognize it, when copying or scanning the dadf jams paper (0094). Some easy access sensors were cleaned and sens init was done, but the paper jam problem persists.
There are other days that the printer does not recognize the adf and error E302 and E280 appear
