Document Specifications Scanning a Mixed Batch 2 Check the following conditions when scanning a batch of documents with different paper weights, friction coefficients, or sizes. Test a few sheets first to check if the documents can be scanned. 2  Paper direction Align the direction of the paper fiber with the feed direction.  Paper weight Use the following paper weights: 11 to 110 lb (40 to 413 g/m2)  Friction coefficient We recommend using the same type of paper from the same manufacturer. Mixing paper from different manufacturers and brands affects the feeding performance as the difference in the friction coefficient increases. We recommend using the following friction coefficients: 0.35 to 0.60 (reference value for paper friction coefficient)  Document position Use paper sizes that fit the 1.54 in. (39 mm) width of the center Pick Up Roller.  Paper size When scanning a mixed batch of different paper sizes, the documents are more likely to skew while feeding because the paper guides do not touch every sheet. Scanned images may have missing portions and document jams may occur. IMPORTANT Check the scanned images to make sure they are straight and complete.  Documents that cannot be scanned in a mixed batch The following types of documents cannot be mixed in the same batch: • Carbonless paper • Bond paper • Perforated documents • Thermal paper • Carbon-backed paper • OHP film • Tracing paper • Synthetic paper • Bent or damaged documents • Thin paper (less than 40g/m2) 56
