It won't copy from top feeder -RESOLVED

My Epson wf2750 will copy when I place paper on the screen but suddenly stopped taking paper from the top feeder where you can put multiple sheets to be copied.

It says remove the document from the glass document will be scanned from the scanner glass, document will be scanned from the scanner glass etc

It is also copying more slowly, even from the screen. IT IS NOW FIXED. THE PAPER SETTINGS ON THE PRINTER HAD BEEN CHANGED
