Summary: The paper feeder on the top pulls multiple pages at once every time. It will then either jam or pull the batch of pages all the way through and copy only the first page. Brother sent me a replacement machine, which did exactly the same thing, so this is apparently a design defect. The only recourse with Brother is for them to keep sending out the same model. Meanwhile, I spent at least five hours on the phone with Brother with phone calls over two separate days.
