Samsung Scx-5935 adf solenoid

I have a Samsung SCX-5935 that has been working well. Now, the adf will feed 2 sheets and stop halfway thru the second sheet. I believe I have a adf solenoid sticking, and I need to put a piece of tape on it to stop it from sticking. Can someone tell me where the solenoid is? I think it is behind the left side cover, but can someone verify that? I have a diagram showing that it is on a motor assembly. Thank you.
