Also, if paper has been removed and torn in the process, there may be a sensor switch stuck which would indicate a jam. Check the entire paper path, there may be a tiny piece of paper that's keepin it from registering a "clear path".
Now that you mentioned "recycled" paper, ensure that if you're using single sided print paper, that you only print on the side intended for printing, which is indicated by an arrow on the end of the package. This will reduce the amount of paper lint in the tops of the rollers which cause slipping and jamming. It's also a good idea to have your printer cleaned at least once a year (more frequently if it's used more). Hiring someone is the safest way to have it cleaned properly, although you can do it yourself with a lint free cloth and some denatured alcohol (used lightly on the rollers/wheels in paper path to remove paper lint and ink).
Have you tried shutting the power off, unpluggin it from the wall, turning the power switch back on and letting it sit there for a while (to think about what it's done
). Sometimes printers jam then just "aren't smart enough" to recognize that the jam is removed.
If it still recognizes a jam, then as projectfocus
said, the toner cartiridge is a good place to start looking.
War produces veterans, wounded both physically and mentally. They have sacrificed for us.....and it is now our job to help these veterans, as they have already helped us in ways we will never know, in ways that we cannot fathom, and in ways that we take granted every day.
