Hi, I'm Pete. Welcome to JustAnswer! I'm reviewing your question now, and will post back with your reply ASAP.
If the machine cannot copy using the ADF then there is likely a problem with the feeder - perhaps a staple or paperclip has got stuck in it, or part of the feed mechanism has got broken.
What have you tried so far? Your initial post just states you have tried "everything"!
Have you opened up the ADF and examined the mechanism?
Have you replaced any parts?
