Hello himsmyboy!

Sikna says

The ADF separation pad is the cause. To remove it lift the cover fully up then use a knife to get under the black tape tab at the top right of the large white foam pad. Pull the tape and the white foam pad loose but not completely - leave the bottom attached. Now you can see the ADF separation pad from below. Use a small screwdriver or spring hook to remove the spring and you will be able to wiggle the ADF separation pad out. First take a good look at how it fits in so you can put it back! The problem is caused by the small black foam pad under the white rubbery tape on the ADF pad assembly. I carefully removed the tape from the back edge to expose the compressed black foam pad. I then cut a matching size of 1/16" foam I had in my shop which was actually HP 98A doctor blade seal foam and just stuck it on top of the old compressed foam. (other similar foam should also work) Then I replaced the white rubbery tape and rubbed the edge down well. I then reinstalled the restored ADF pad and the spring which holds it. Last I just pressed the large white foam pad back into position - being sure to pull it with a slight tension as I pressed into place. This fixed the ADF feed and it worked like new again...

Sikna out...
