This printer is designed with a dual toner/drum chamber. Do not separate these two parts. Upon opening the lid, you will find the toner/drum assembly right in front of you. Pick it up with both hands and pull straight up. After that, you should be able to take the jammed papers. Know this: once a paper is jammed, printing another paper will NEVER take the first out. Just make sure to remove the complete papers. If they break, make sure you extract all the pieces.

I found the solution here.
A plastic thing was closing the sensor window. Open the window and you will solve the problem.

Unfortunately this may require and engineers visit. If you pull down the MP assembly by using the handle in the middle at the front of the printer you can then see a small "gearbox" at the right hand side of the transfer belt. This is common to feeds from both trays and could be worn. If you remove tray 1 and temporarily tape up the sensor arms to fool the printer into thinking it has a full tray installed, you can the test, by applying a little pressure to the feed roller, to see if it positively moves forward or if you are able to stop it turning. On a brighter note, you may just need new rollers instead of cleaning them.
