Multi Purpose Tray Cassette or Multi Purpose Tray Envelope #10 (Commercial #10) (4 1/8 × 9 1/2") Legal Envelope #9 (Commercial #9) (3 7/8 × 8 7/8") Letter Envelope #6 (Commercial #6 3/4) (3 5/8 × 6 1/2") Letter-R Envelope Monarch (3 7/8 ×7 1/2") Statement-R Youkei 2 (114 × 162 mm) Oficio II Youkei 4 (105 × 235 mm) 8.5 × 13.5" Size Entry (98 × 148 to 297 × 432 mm) 8K (273 × 394 mm) 16K (273 × 197 mm) 16K-R (197 × 273 mm) Smoothness The paper surface should be smooth, but it must be uncoated. With paper that is too smooth and slippery, several sheets may accidentally be supplied at once, causing jams. Basis Weight In countries that use the metric system, basis weight is the weight in grams of one sheet of paper one square meter in area. In the United States, basis weight is the weight in pounds of one ream (500 sheets) of paper cut to the standard size (or trade size) for a specific grade of paper. Paper that is too heavy or too light may be supplied incorrectly or cause paper jams, which may cause excessive wear of the machine. Mixed paper weight (i.e., thickness) may cause several sheets to be supplied at once accidentally and may also cause blurring or other printing problems if the toner fails to adhere correctly. The recommended basis weight is between 60 and 163 g/m2 for the cassettes and between 60 to 220 g/m2 for the multi purpose tray. Thickness Avoid using paper that is too thick or thin. Signs that paper may be thin include frequent problems with paper jams or with several sheets being supplied at once. Paper jams may also indicate that the paper is too thick. The proper thickness is between 0.086 and 0.110 mm. Moisture Content Paper moisture content is the ratio of moisture to dryness expressed as a percentage. Moisture affects how the paper is supplied, the electrostatic changeability of the paper, and how the toner adheres. Paper moisture content varies depending on the relative humidity in the room. High relative humidity causes paper to become damp, making the edges expand so it appears wavy. Low relative humidity causes paper to lose moisture, making the edges tighten and weakening print contrast. Wavy or tight edges may cause the paper to slip when it is supplied. Try to keep the moisture content between 4 to 6%. To maintain the right level of moisture content, bear in mind the following considerations. OPERATION GUIDE Appendix-13
