Paper and specialty media guidelinesPaper and specialty media are paper, card stock, envelopes, paper labels, and transparencies. A number of itemsmust be considered concerning the selection of paper and specialty media before printing. This chapter providesinformation on making selections and caring for papers and specialty media.It is recommended that you try a limited sample of any paper or specialty media you are considering using with theprinter before purchasing large quantities.Paper guidelinesSelecting the correct paper or specialty media reduces printing problems. For the best print quality, try a sample ofthe paper or specialty media before buying large quantities.Paper characteristicsThe following paper characteristics affect print quality and reliability. Consider these characteristics when evaluatingnew paper stock.WeightThe printer trays can automatically feed paper weights up to 90 g/m 2 (24 lb bond) grain long paper. The multipurposefeeder can automatically feed paper weights up to 163 g/m 2 (43 lb bond) grain long. Paper lighter than 60 g/m 2(16 lb) might not be stiff enough to feed properly, causing jams. For best performance, use 75 g/m 2 (20 lb bond) grainlong paper. For paper smaller than 182 x 257 mm (7.2 x 10.1 in.), we recommend 90 g/m2 (24 lb) or heavier paper.Note: Duplex printing is supported only for 60–90 g/m 2 (16–24 lb bond) paper.CurlCurl is the tendency for paper to curl at its edges. Excessive curl can cause paper feeding problems. Curl can occurafter the paper passes through the printer, where it is exposed to high temperatures. Storing paper unwrapped inhot, humid, cold, or dry conditions, even in the trays, can contribute to paper curling prior to printing and can causefeeding problems.SmoothnessPaper smoothness directly affects print quality. If paper is too rough, toner cannot fuse to it properly. If paper is toosmooth, it can cause paper feeding or print quality issues. Always use paper between 100–300 Sheffield points;smoothness between 150–250 Sheffield points produces the best print quality.Moisture contentThe amount of moisture in paper affects both print quality and the ability of the printer to feed the paper correctly.Leave paper in its original wrapper until it is time to use it. This limits the exposure of paper to moisture changes thatcan degrade its performance.Condition paper before printing by storing it in its original wrapper in the same environment as the printer for 24 to48 hours before printing. Extend the time several days if the storage or transportation environment is very differentfrom the printer environment. Thick paper may also require a longer conditioning period.Paper and specialty media guidelines45
