July 3, 2009
frequent jams on DF611 :
1. multiple feeding : swing up the adf paper feed tray. Under tray you will find a spring that press the separating roller (blue one). Set this spring on the lower position.
2. jams at the last sheet of paper :swing up-at left only upper side of the adf paper feeed tray, swing up -at right elevator tray and remove it. Under elevator tray you will see a large white plastic part .this part lift up the elevator tray.On this part (white) you will see 2 small holes (like screw holes) insert in those holes 2 screws and screw it so remain only 2-4 mm out on white part

The other reason for multiple jam on DF611 is bad setting of photo interrupter: to solve this -open-remove upper cover of paper df tray -inside you will find 3-4 photo interrupter .These is just inserted in their holes but it’s not fixed.When Df work and vibrate -these interrupter move freely in that holes. For best results you can use a quick adhesiv(bond) to fix it in right position
