Weight The basis weight for the paper should be 60 to 100 g/m (16 to 27 lb). Composition Plain bond paper of one of the following compositions should be acceptable for regular use: No. 1 sulphite (100% chemical wood pulp) 25% to 100% cotton content Performance Considerations For optimum performance: Use 75 to 80 g/m (20 to 24 lb), 25% or 50% cotton content plain paper. Restrict printing to 6.35 mm (0.25 in.) from the left and right margins and 6.35 mm (0.25 in.) from the top and bottom edges. Keep at least three sheets in the selected input bin (paper load failure frequency increases otherwise). All input bins are capable of handling multiple-part forms. Multiple-part forms present special considerations because of their complexity. There are many different types of multiple-part forms available. Use only snap-out or top-glued multiple-part forms on the ASF. Form sets should be operationally tested before regular use. For specific information about multiple-part forms, see IBM 4230 Printer Auto Sheet Feeder General Information. Some forms such as highly embossed papers (many stock certificates), coated papers, and multiple-part forms that do not conform to specifications will not feed reliably by the ASF. Forms are available from IBM or any forms supplier. Appendix C. Forms Information C-5
