SAFETY INFORMATION Mark Contents WARNING indicates a potentially hazardous situation which, if not avoided, could result in death or serious injuries. CAUTION indicates a potentially hazardous situation which, if not avoided, may result in minor or moderate injuries. IMPORTANT indicates a potentially hazardous situation which, if not avoided, may result in damage to property or loss of product functionality.
Page 18 To use the Machine Safely WARNING ELECTRICAL HAZARDS Failure to follow the warnings in this section may create the risk of an electrical shock. In addition, you could create an electrical short, which may create the risk of a fire. There are high-voltage electrodes inside the machine.
Page 19 - DO NOT use the machine or handle the cord if the cord has become worn or frayed. If unplugging your machine, DO NOT touch the damaged/frayed part. - Brother strongly recommends that you DO NOT use any type of extension cord. DO NOT use this product during an electrical storm.
Page 20 CAUTION DO NOT sit or stand on the machine or use it for any purpose beyond its intended purpose. If the machine becomes hot, releases smoke, or generates any strong smells, immediately unplug the machine from the AC power outlet. Wait until pages have excited the machine before picking them up.
Page 21 When changing the lower tray size from the Ledger, A3 or legal size to the original size, be careful not to pinch your fingers in the gaps or slots in the bottom of the tray. It may cause injury to you. DO NOT touch the area shaded in the illustration.
Page 22 Carry the machine by sliding your hands into the hand hold indentations located on each side of the machine. (MFC-J3520/J6520DW) (MFC-J3720/J6720DW/J6920DW and MFC-J6925DW only) To prevent injuries when moving or lifting this machine, make sure to use at least two people.
Page 23 When carrying the machine, remove the lower tray if it has been expanded to hold large paper such as Ledger, A3 or legal size paper. The weight of the paper could cause the lower tray to fall and cause injury to you. (MFC-J6520DW) Do not remove the serial number and instruction labels that are affixed to the machine.

Page 32 Recommended print media To get the best print quality, we suggest using Brother paper in the table. If Brother paper is not available in your country, we recommend testing various papers before purchasing large quantities. We recommend using "3M Transparency Film" when you print on transparencies.
Page 33 Handling and using print media  Store paper in its original packaging and keep it sealed. Keep the paper flat and away from moisture, direct sunlight and heat.  Avoid touching the shiny (coated) side of photo paper.  Avoid touching either side of transparency paper because they absorb water and perspiration easily, and this may cause decreased output quality.
