Question about Epson WorkForce WF-3520 All-in-One Inkjet Printer

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: ADF Jam... Service req c2011
Can be a tough one.
1st - Open the ADF & make sure that the 2 little Sensor tabs move freely.
2nd - Lift the ADF & check that the White Plastic Paper Guide is "down in the slot" & not resting on edge of the white flat bed scan pad or overlapping the scan pad.
For some C Error Codes
Check for electrical interference from external devices.
Disconnect the Printer from all devices, and run a test print..
Here are the "c2011 error" fixes per the manufacturer:
Replace the Automatic Document Feeder.
Replace the Scanner.
Replace the Main Board.
You might try unplugging the ADF & see if you can operate without it.
If you unplug the scanner, the printer might not function.
