<If it looks like you are unable to fix the problem>
Turn off the printer, disconnect the power cord from the AC outlet, and contact your
dealer or Brother authorized service representative for assistance.
Do not make any changes or modifications to the equipment, as this may cause a fire or
an electric shock.
Turn off the printer and disconnect the power cord from the AC outlet before performing
maintenance on the printer. Failure to turn off the printer and disconnect the power cord
may result in an electric shock.
