It sounds like you either have a broken actuator or a sensor has gone bad. Are you a tech or end user?

Greetings from over the wall!!
Any joy with the ADF?

check for dirty reflectors or dirty felt pads where any optical sensors are. The reflectors look like tin foil and the felt pads are black patches. If they are dirty enough, a false jam will be the result.

most common problems that i have had with ADF`s generally are with pieces of paper or staples blocking sensors, once I found entire postit ( 75x75 mm ) in the ADF, once I found a Fly sticked to the sensor )))

Just like everyone else said, check all the sensors and unblock/clean them

Well i have fixed it, the sensors were all fine and there was no fly stuck to a postit note inside the df. It actually turned out to be the PBA control board in the doc feeder. I had another machine there so i swapped the boards and the fault was cleared. thanks anyway for all suggestions, a good one to remember for the future

cheers matt

I have the same problem and I can not figure out what the problem is. I do see the foil and it looks clean. where are other sensers that I can clean.

Kingmony check the the shaft were the primary feed tires are on the feeder entrance. There is a groove on the shaft just outside of each tire. There is a small white plastic arm about 1 inch long that snaps on the grooves (both sides). If one of these plastic arms is missing or on backwards the shaft will hit the paper entrance sensor and show a jam.
