Black-and-white Copiers Do They Still Fit Your In-plant?

Let's say one manufacturer has a 70-ppm copier that is at the bottom of a family range of 70-ppm to 105-ppm. Another has a 70-ppm copier that is on the top of a family range of 40-ppm to 70-ppm. That engine has been "stretched" to accommodate the increased speed and may be less heavy duty than the other manufacturer's copier. Ask for proof sources of any claims the manufacturer makes as to the productivity of a digital copier.
