SAFETY INFORMATION WARNING WARNING indicates a potentially hazardous situation which, if not avoided, could result in death or serious injuries. CAUTION CAUTION indicates a potentially hazardous situation which, if not avoided, may result in minor or moderate injuries. IMPORTANT IMPORTANT indicates a potentially hazardous situation which, if not avoided, may result in damage to property or loss of machine functionality.
Page 13 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 14 DO NOT take apart or attempt to convert the machine. This may create a risk of fire or electrical shock. Such conduct may also be punished by the law. If the machine has been dropped or the casing has been damaged, there may be the possibility of an electrical shock.
Page 15 FIRE HAZARDS Failure to follow the warnings in this section may create the risk of a fire. DO NOT use flammable substances, any type of spray, or an organic solvent/liquid containing alcohol or ammonia to clean the inside or outside of the machine. Doing so could cause a fire or electrical shock.
Page 16 CAUTION * There are cases where other models are used in the illustrations. Wait until pages have exited the machine before picking them up. Failure to do this may cause injury to your fingers by trapping them in a roller. DO NOT put your hand or any foreign objects into the ink insertion slot.
Page 17 When changing the tray size from the Ledger, A3, Legal or Folio 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. (MFCJ2730DW/J5730DW/J5930DW) To prevent possible injuries, at least two people should lift the machine.
Page 18 DO NOT carry the machine by holding the areas shown in the illustrations. Doing this may cause the machine to slip out of your hands and may result in injury. Confidential...
Page 19 Carry the machine by sliding your hands into the handhold indentations located on each side of the machine. When carrying the machine, remove the trays if they have been expanded to hold large paper such as Ledger, A3, Legal or Folio size paper. The weight of the paper could cause the trays to fall and cause injury to you.
Page 20 If the ink contacts your skin or gets into your eye or mouth, please follow these steps immediately: - If your skin comes into contact with the ink, wash your skin with water and soap immediately. - If the ink gets into your eye, rinse it with water immediately. If left as is, it may cause redness or mild inflammation of the eye.
Page 21 Precautions for Troubleshooting and/or Disassembly/Assembly Be sure to observe the following warnings and precautions to prevent any secondary troubles from happening by mishandling the machine during troubleshooting and/or disassembly/ assembly. Precautions  Be sure to observe the following to prevent any secondary troubles from happening during troubleshooting and/or disassembly/assembly.
Page 22 (16) Before packing the machine for sending it back to the user after repairs, be sure to clean the flushing guide with a cleaner stick as shown below to prevent ink splashing during transportation. Flushing guide Cleaner stick Flushing base Confidential...
