Is there a way to choose black and white default for copying on the 7855i copier rather than AutoDetect. Some documents may only have a blue ink signature but we do not need our copy to be colored. Our older model Xerox defaulted to black and white unless we chose autodetect or color and that is what we would like our new machine to do as well.
Thank you.
