There should be two to three, one in the feed area, one in the middle, and one close to the exit. I don't klnow which kind your particular model uses but i'll describe both, also you may not always be able to see them because sometimes they are located under or near a guide plate. 1) electromagnetic/photo interupt sensors are always mechanical in nature they use a tiny magnet/photo sensor that sits on an arm that when the paper goes through it pushes the arm up/down causing the magnet to move near or away from the read switch, the are usually black in color, about 1/2 in wide with the arm 1/16 in with and you will be able to lightly push them up or down if you can see them. the other kind is a photo sensor which is even smaller 1/2 in X 14 in and it shoots a beam up onto a black felt patch(these are usually used under guide plates) where if the black felt is blocked or dirty it will cause this simptom. another thing you can try is to try using a very thin credit card to see if a sensor is blocked by carefully inserting it in where the paper goes in or come out but be ver carefull not to damage anything. I hope this will help you. Good Luck

Thank You,
