NOTE: Illustrations shown below are from a representative product and operating system, and may differ from your Brother machine and operating system. To set the automatic 2-sided or booklet print in the printer driver, follow the instructions listed below: Printing on print media heavier than 105 g/m 2 (28 lb) will cause smears and excessive paper curling. The machine can print in 2-sided if the print media is 60 to 105 g/m 2 (16 to 28 lb) plain paper. If the paper continues to curl, replace the paper. If the paper is not feeding correctly, it may be curled. If paper is curled, straighten it and put it back in the paper tray. Use A4, Letter, Legal, or Folio size paper when you use the automatic 2-sided printing function.
