Continuous Forms - F1 or F2 Dimensions Forms Width Length Maximum 381 mm (15 in.) 355.6 mm (14 in.) Minimum 76.2 mm (3 in.) 76.2 mm (3 in.) Thickness The thickness of all forms should be a minimum of 0.08 mm (0.003 in.) and a maximum of 0.64 mm (0.025 in.). Acceptable print quality will be provided on up to four-part forms. Up to six-part forms can be used; however, for best feeding and stacking, a maximum of four parts is recommended. If you use forms having more than four parts, you should test them for forms handling, print registration, and print quality. Weight Minimum weight for single-part forms is 56 g/m (15 lb). Maximum weight for single-part forms is 150 g/m (40 lb). The best range is 60 to 90 g/m (16 to 24 lb). Paper weights outside the functional range should be tested by the user. For multiple-part forms, the paper weight of individual sheets can be as low as 45 g/m (12 lb). Individual sheets below this limit should be tested by the user. Performance Considerations For optimum performance, printing should be restricted to 6.4 mm (0.25 in.) from all edges, holes, or folds on the forms. Forms are available from IBM or any forms supplier. C-2 User's Guide
