Then take that figure and increase it by 30 percent. That's approximately the monthly copy volume you should look for in a model. All copiers, as you will see when you compare models, come with a suggested monthly copy volume. This number is suggested by the manufacturer and is notoriously inflated beyond the copier's optimum performance. If you buy a copier with a monthly copy volume that exactly matches your actual office use, you'll end up overworking it.
Overuse is bad.
Overworking a copier is the quickest way to a service call. In fact, most warranties will hold you liable for repair costs if it's determined you've overused the machine. You need room for growth. If you will be doing these types of copying, make sure you don't mind the slower speed. It may be longer than you are willing to wait.
