Getting started > 20Paper RecommendationsYour unit will handle a variety of print media, including a range of paper weights and sizes,transparencies and envelopes. This section provides general advice on choice of media, andexplains how to use each type.The best performance will be obtained when using standard 20 to 24 lb. US Bond (75 to 90g/m≤) paper designed for use in copiers and laser printers. Use of heavily embossed or veryrough textured paper is not recommended.Pre-printed stationery can be used, but the ink must not offset when exposed to the highfuser temperatures used in the printing process.Envelopes should be free from twist, curl or other deformations. They should also be of therectangular flap type, with glue that remains intact when subjected to hot roll pressurefusing used in this type of unit. Window envelopes are not suitable.Transparencies should be of the type designed for use in copiers and laser printers. Westrongly recommend Oki transparencies (Order No. 52205701). In particular, avoid officetransparencies designed for use by hand with marker pens. These will melt in the fuser andcause damage.Labels should also be of the type recommended for use in copiers and laser printers, inwhich the base carrier page is entirely covered by labels. Other types of label stock maydamage the printer due to the labels peeling off during the printing process. A suitable typeis Avery White Laser Label type 5161 (Letter) or types 7162, 7664, 7666 (A4).Cassette TraysIf you have identical paper stock loaded in another tray (2nd/3rd tray if you have one, orthe multi purpose tray) you can have the unit switch to another tray when the current trayruns out of paper. When printing from Windows applications, this function is enabled in thedriver settings. When printing from other systems, this function is enabled in the PaperSetup menu (See ìPaper Setupî on page 30).If fitted, tray 2 (or 3) may be removed and replenished while the machine is being fed fromtray 1. Tray 1 cannot be removed while the machine is being fed from tray 2 (or 3) becauseparts of tray 1 are used to guide paper fed from tray 2 (or 3).SIZE DIMENSIONS WEIGHTLetter 8.5 x 11 inches Light17-22 lb.
