General Guidelines U. S. Bond Weight (lb) Europe Metric Weight (g/m²) Table 2-3 Paper Weight Equivalence Table Paper weight is listed with expression in U.S. bond weight (lb) and European metric (g/m²). The shaded point indicates the standard weight. 16 17 20 21 22 24 27 28 32 34 36 39 42 43 47 53 60 64 75 80 81 90 100 105 120 128 135 148 157 163 176 199 Thickness (Caliper) Thick paper is referred to as high-caliper paper and thin paper as lowcaliper paper. The paper used with the printer should be neither extremely thick nor extremely thin. If you are having problems with paper jams, multiple feeds, and faint printing, the paper you are using may be too thin. If you are having problems with paper jams and blurred printing, the paper may be too thick. The proper thickness is 0.086 to 0.110 mm (3.4 to 4.3 mils). Moisture Content Moisture content is defined as the percent ratio of moisture to the dry mass of the paper. Moisture can affect the paper's appearance, feedability, curl, electrostatic properties, and toner fusing characteristics. The moisture content of the paper varies with the relative humidity in the room. When the relative humidity is high and the paper absorbs moisture, the paper edges expand, becoming wavy in appearance. When the relative humidity is low and the paper loses moisture, the edges shrink and tighten, and print contrast may suffer. Wavy or tight edges can cause misfeeding and alignment anomalies. The moisture content of the paper should be 4 to 6%. To ensure the proper moisture content, it is important to store the paper in a controlled environment. Some tips on moisture control are: • Store paper in a cool, dry location. • Keep the paper in its wrapping as long as possible. Rewrap paper that is not in use. • Store paper in its original carton. Place a pallet, etc., under the carton to separate it from the floor. • After removing paper from storage, let it stand in the same room as the printer for 48 hours before use. • Avoid leaving paper where it is exposed to heat, sunlight, or damp. 2-5
