Paper facts • Do not use cut-sheet check paper that was converted from fanfold by the paper distributor. This conversion process can result in dimensional inaccuracy, poorly cut edges, and unacceptable paper curl. MICR paper requirements Paper characteristics Basis weight Sheffield smoothness Grain direction Moisture content Reflectance Curl Perforations Metallic content Stiffness Cutting precision Coating Lamination Preprinting ink Size The following table summarizes Xerox's recommendations for papers that are used for MICR printing. Papers with the following characteristics perform best in Xerox MICR printers. Table 3-1. Xerox paper recommendations Recommended for optimal printer and reader/sorter performance 24-pound/90 gsm 80 to 150 Parallel to the long edge of check or MICR document. Short grain direction may be acceptable for personal, 6 inch/152 mm checks. 3.9 to 5.e per cent 60 percent minimum Refer to instructions in your MICR printing system operator guide 60 to 80 ties per inch No ferromagnetic materials can be present in the paper. For recommendations, refer to "Paper stiffness," later in this chapter. +/- 0.030 inch/0.762 mm length +/- 0.030 inch/0.762 mm width Do not use paper containing clay or resin coatings. Do not use stock that is a combination of paper and plastic. Must be heat resistant to approximately 400 degrees F/204 degrees C for laser printing. Heat resistance varies according to manufacturer. Refer to instructions in your MICR printing system operator guide Basis weight Basis weight is an industry term for expressing the weight per unit area of paper. Paper weight is generally expressed as grams per square meter (gsm), a measure that makes it easy to compare any two pieces of paper, even if the papers are of different types, such as offset and index. 3-2 Generic MICR Fundamentals Guide
