SOURCE: Document feeder works for printing but not for scanning
Hi, When you had the doucment feed jam were you able to clean or remove any paper that might be blocking the paper to be scanned? It sounds like there is paper still in the document feeder , I would open the DF and check very closely to make sure no paper is in the way!Good Luck!

I think I found my answer. You don't have to un do any screws. Lift up the cover to the automatic feeder. You will see a spring on the side of the mechanism towards the front; remove the spring; that will allow you to lift up the little arm the spring was attached to and remove the roller or bar and the light blue/green plate just under it. Then you will be able to see the jammed paper, which which I was able to carefully pull out with a pair of tweezers. Some was under rubber rollers, but when I pulled the paper sideways it slipped out. Now it works!

It sounds to me like the switch that senses when paper is present is blocked or out of position.
The User Manual and such does not provide sufficient detail for me to decipher what type of switch is used. It is either going to be a switch that is depressed to close the circuit when paper is present and is held down somehow now, or it is a proximity sensor and there is dirt or whatever on the sensor that is enough to make it think there is paper there. It should be something that appears to be a tiny window, and it would need to be cleaned with a qtip or 100% cotton cloth and isopropyl alcohol.
You will likely need to remove the ADF feeder cover to obtain full access to the ADF mechanism and find the sensor, since it is most likely recessed in the ADF quite a ways.
The other possibility is that the wire for the sensor has been damaged after a jam or something of that nature.
If you have searched for the sensor and cannot locate it / clear the error, then you will need to have a service tech work on the machine.

I'm sure this will solve your issue.
