Special Paper The table below lists the specifications for adhesive label paper. Item Weight of top sheet Composite weight Thickness of top sheet Composite thickness Moisture content Specification 44 to 74 g/m² (12 to 20 lb/ream) 104 to 151 g/m² (28 to 40 lb/ream) 0.086 to 0.107 mm (3.9 to 4.2 mils) 0.115 to 0.145 mm (4.5 to 5.7 mils) 4 to 6 % (composite) Envelopes The printer can print on envelopes using paper with a basis weight of 60 to 79 g/m2 (16 to 21 lb/ream). Envelopes must be manually fed. An envelope is a more complex object than a single sheet of paper. For this reason, it may not be possible to obtain consistent print quality over the entire envelope surface. Many envelopes have a diagonal grain orientation (See Paper Grain on page 2-6). This orientation is more likely to wrinkle and crease on its way through the printer. Before purchasing envelopes for use with the printer, test a sample to verify the envelope's suitability. Do not use envelopes that have an encapsulated liquid adhesive. Avoid long printing runs consisting of envelopes only. Extensive envelope printing can cause premature printer wear. To avoid jamming due to curled envelopes, do not leave more than approximately 10 printed envelopes stacked in the paper trays during multiple envelope printing. Colored Paper Colored paper should satisfy the same conditions as white bond paper, listed in Paper Specifications on page 2-2. In addition, the pigments used in the paper must be able to withstand the heat of fusing during the printing process (up to 200 °C or 392 °F). Preprinted Paper Preprinted paper should have a bond paper base. The preprinted ink must be able to withstand the heat of fusing during the printing process, and must not be affected by silicone oil. Do not use paper with any kind of surface treatment, such as the type of paper commonly used for calendars. 2-9
