your pacemakers when near the machine, move away from the machine and consult a doctor
immediately.
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

(MFC-J4710DW)
If the lower tray has been expanded to hold large paper such as Ledger, A3 or Legal size paper,
position the machine so that the tray will not protrude past the edge of the table or desk. When
the lower tray is expanded, it will protrude from the machine. Therefore, if someone hits the tray,
the machine could fall and cause injury.
