SOURCE: False Paper Jam Error
Make sure the paper tray guides are set against the paper more likely to be the back guide not pushing the paper to the front of the tray. If you have the guides set correctly then place one sheet of paper in the tray and blot some methylated spirits on the leading edge along the page width and close the tray and try printing something.
You will have a jam repeat process 3 or 4 times then open tray and remove paper. Where you soaked the spirits into the paper there should be a grubby mark where the feed roller has rubbed and cleaned. Wipe the tray dry and put fresh paper in then hopefully you will now be able to print. If you cannot then the likely thing is that the paper feed pickup spindle is broken and will need replacing.
Hope this helps you and please rate me

Most likely a bad pick up roller these machines will give a jam error if the paper or envelope is not picked up. Try cleaning the roll for the tray you are having the trouble with if the condition improves you have found the problem.
Hope this helps
