I have been having some issues with the right feeder (labeled 2) on my S3. I looked up how to increase the tension on my S3. When I tried to increase the tension, I noticed that the tension screw is different from my left feeder (labeled 1) and doesn't seem to function correctly. It looks like one of the normal screws used to attach the feeder itself. I've attached a picture. Is this normal? Can I buy the correct tension screw separately somewhere?
