HP LaserJet 4

My Laserjet 4 printer doesn't work. It shows that it has a paper jam but there is no paper hanging in the printer. When you start the printer it normally starts one time but now it doesen't. Does anyone know a solution??

Thanks a lot,


An educated guess would be a stuck exit sensor arm in the fuser assembly. Open the rear door and you'll see the arm on the top right of the fuser assembly. It goes up into the printer and blocks and unblocks a light beam shining on a photocell. This tells the printer when the paper reaches the fuser and when it leaves it. If the arm is stuck, the printer thinks there is paper in the fuser assembly. If you can't free it, you might want to pull the assembly out carefully, just 2 screws in the bottom of it.
