Loading paper that is stuck together, frayed, curled or bent can cause a jam. Overloading the paper tray, loading different thicknesses of paper in the tray or using paper that isn`t appropriate for your particular printer can all result in a jammed printer.

Paper jam in tray 2 (but no paper pulled from tray) also M476DN models
ANSWER : Isopropyl alcohol is not recommended for rubber rollers. It dries out the rubber and hasten it’s cracking and breaking. It will do nothing to restore the grip. Those rollers are really hard to replace. It would be easy if that dumbass secondary menu really worked. None of the techs I’ve spoke to ever got into it.

ANSWER : Obviously you didn’t get all the paper cleared out. There is a small scrap in the paper path causing the jam when the paper hits it. You can try clearing it out by inserting something stiff like a piece of file folder from the back of the printer into the paper path and pushing the offending piece out that way.
