Picks up a second sheet of paper and jams
The printer regularly picks up a second sheet of paper which causes a jam. I have fitted a new roller which doesn't help at all and cleaned everything visible. This happens both with the bottom feeder tray and the manual sheet feeder. It's getting worse, so that now it even does it on a single page job. Printer has done a total of 10k pages and 500 odd on the current cartridge.
