I had a very similar problem with the ADF, it resulted in ADF paper jam - message and then in Req Code 2011.
I checked sensors and everything else, then called a epson service professional.
After telling him the Req Code, he knew the problem and said that the problem is the board, which needs to be exchanged, mentioning that this spare part is expensive.
I then checked the whole ADF again, now opening the long grey cover on the backside, I disonnected the connector cable from both sides and - using a multimeter - checked this connector cable for breaks.
Result: the violet cable was broken, so I soldered in a new wire, using the last cm of (old) wire on each side - and now the ADF works fine.
This cable is easy to change if you get the spare part, there is a connector plug on each side, on the ADF side is an additional ground wire (green) fixed with a single screw. Thats it !
For the electronic experts: the configuration of the connector:
sourrounding metal cover = ground, thick green Wire on the ADF side
If you turn the plug that way, that the two single contacts are on top, these are the colours:
1st row: brown - black
2nd row: green - yellow - orange - red
3rd row: grey - violet - blue
Hope this helps

SOURCE: Paper Jam...grinding noise
The print head lock is probably not retracting. Look for the white plastic block that pokes through from the paper feed side just in front of the head. Push it in with your finger and move the head to the middle by hand. Now turn the machine on. Then turn it off using the correct method. Then turn it on once more. If it starts grinding again, you screwed the feed mechanism when tugged out the jammed paper (probably pulled it backward through the feed instead of making it go forward and out the correct exit). If this is the case, you may as well bin it. If it in warranty, you can try to get a claim for repair.

Turn the printer off and on to see if it can automatically clear some or all of the jam. Many printers provide an error-code listing on the front panel display for the area where the jam occurred. If your printer shows an error code, be sure and check the printer manual to see if that identifies the area of the printer where the jam occurred.
Turn off the printer.
Remove any paper trays. Inspect them for wrinkled or damaged paper.
Open any other doors that give access to the printer's paper path and to the toner or ink cartridge.
If necessary, remove the toner or ink cartridge. Place it in a bag or away from light to avoid damaging it.
If you find a piece of jammed paper, remove it by holding it with both hands and pulling firmly (see A). The goal is to keep the paper from tearing. If several pieces are jammed together, try pulling out the middle piece first to loosen the jam.
If the paper does tear, try rotating the roller gears manually to free the paper (see B). Don't force anything, though.
Replace the toner or ink cartridge and paper trays, close any doors you opened and turn the printer back on.
If the printer paper jam message still appears, then there is still some paper in the printer. Reinspect the paper path.
