I have a black line down the scanned page from the ADF Feeder in my MX920. It prints fine from the platen. I've cleaned the ADF several times. On the white bar in the ADF feeder there is a blackening, which looks like either ink or like the plastic has come up and there is black underneath. In any event, not amount of cleaning or rubbing gets rid of it.
