It looks like the ADF switches are ok.
Open top cover - message to close cover.
Open adf off glass - message to close adf.
original in adf - message to remove original (after open top cover and close.
ADF roller is down and doesn't lift, and when I run copy it scan from the glass and doesn't feed the original.
I have the service manual but there is nothing there in regard to the ADF troubles. (ADF=Document processor).
