Using Paper Understanding Paper Ream Labels Understanding Paper Ream Labels Figure D-2, shown below, is an example of a typical label from a ream of paper. It includes much of the information about paper use and paper specifications. Figure D-2 Paper Ream Label details General Guidelines Some general guidelines to follow when selecting media are summarized on the following pages. Use conventional white xerographic paper for most printing. The paper should be of high quality, free of cuts, tears, grease spots, loose particles, dust, wrinkles, voids, and curled or bent edges. Xerographic papers, also called photocopy or xerocopy papers, are usually made from chemical wood pulp and are characterized by a smooth surface, controlled electrical properties, heat stability, and cleanliness. These characteristics ensure good image transfer, fusing without excessive curl, and reliable printer operation. Some applications may require a paper having a more prestigious look or feel. Bond papers generally have a watermark and often use cotton fiber. These papers tend to have a rougher surface and their properties may not be controlled like xerographic papers. However, your D640 printer will print satisfactorily on many of these bond papers. Also, some paper manufacturers are now making laser grade bond papers which have properties compatible with laser quality printing. One of the most important things you can do to ensure the best possible performance from your D640 printer is to select a quality paper. Table D-4, "Recommended paper specifications", summarizes the specifications of a paper that will give you the best performance. Using Paper D-9
