Toner is the most important part of your Xerox printer or multifunction printer. Without toner you basically have a large scanner or paperweight. Obviously, we recommend that you use genuine Xerox toner in your machines. You might be tempted to use a bargain toner but I would like to caution you against trying the bargain brands. In the case of toner, you really do get what you pay for. In the end bargain toner can end up costing you more by causing problems with the printer and causing you large replacement or repair bills. The quality of your prints may suffer and you could lose valuable business because of poor quality output.
