To use the Machine Safely
Please keep these instructions for later reference and read them before attempting any
maintenance. If you do not follow these safety instructions, there is a possibility of a fire,
electrical shock, burn or suffocation.
WARNING
DO NOT expose the machine to direct sunlight, excessive heat, open flames,
corrosive gasses, moisture or dust.
DO NOT place your machine on a carpet or rug, as this will expose it to dust. Doing
so may create a risk of an electrical short or fire. It may also damage the machine
and/or render it inoperable.
DO NOT place the machine near heaters, air conditioners, electric fans, refrigerators,
radiators, or water. Doing so may create the risk of a electrical short or fire should
water come into contact with the machine (including condensation from heating, air
conditioning, and/or ventilation equipment that may be sufficient to create a electrical
shock, short circuit or fire).
DO NOT place the machine near chemicals or in a place where chemicals could be
spilled on it. Should chemicals come into contact with the machine, there may be a
risk of fire or electric shock. In particular, organic solvents or liquids such as benzene,
paint thinner, polish remover, or deodorizer may melt or dissolve the plastic cover
and/or cables, resulting in a risk of fire or electric shock. These or other chemicals
may also cause the machine to malfunction or become discolored.
The product should be placed so as not to come into contact with any wall or other
device. Otherwise, it could create a risk of overheating and/or fire.
Instead:
• Place the machine on a solid surface, never on a bed, sofa, rug, or other similar soft
surface.
• Do not place this machine in a “built-in” installation unless adequate ventilation is
provided.
Slots and openings in the casing, back or bottom of the product are provided for
ventilation. To avoid blocking or covering these openings, the product should be
placed where it will not touch any wall or other device. Blocking the unit's ventilation
could create a risk of overheating and/or fire.
IMPORTANT
• Always place the unit on a solid surface, never on a bed, sofa, rug, or similar soft
surfaces.
• DO NOT place the unit in a "built-in" installation.
CAUTION
Avoid placing your machine in a high-traffic area. If you must place it in a high-traffic
area, ensure that the machine is in a safe location where it cannot be accidentally
knocked-over, which could cause injury to you or others and serious damage to the
machine.

vii Confidential
Ensure that cables and cords leading to the machine are secured so as not to pose a
tripping hazard.
DO NOT place this machine on an unstable or tilted cart, stand, table or on any tilted/
slanted surface. The machine is heavy and may fall, causing injury to you and serious
damage to the machine.
Make sure that no part of the machine protrudes from the desk or stand where the
machine is located. In particular, do not leave the output tray open and extended
beyond the edge of a cabinet, table or stand when the machine is located on the edge
of a cabinet, table, stand, etc. As previously cautioned, make sure that the machine is
located on a flat, level, and stable surface free from vibration. Failure to observe these
precautions could cause the machine to fall, causing injury to you or others and
serious damage to the machine.
Important
• DO NOT place your machine next to sources of interference, such as speakers or
the base units of non-Brother cordless telephones. Doing so may interfere with the
operation of the machine's electronic components.
• DO NOT connect your machine to an AC power outlet controlled by wall switches or
automatic timers. Disruption of power can delete information from the machine's
memory, and repeated cycling of the power can damage the machine.
• DO NOT put objects on top of the unit.
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.

viii Confidential
There are high-voltage electrodes inside the machine. Before you access the inside
of the machine, including for routine maintenance such as cleaning, make sure you
have unplugged the power cord from the AC power outlet, as well as unplugged any
Ethernet cables from the machine.
DO NOT push objects of any kind into the machine through slots or openings in the
casing, as they may touch dangerous voltage points or short out parts.
DO NOT continue using the machine if it has been dropped or the cabinet has been
damaged. Instead, unplug the machine from the power outlet and contact Brother
Authorized Service Personnel.
The machine should be connected to an AC power source within the range indicated
on the rating label. DO NOT connect it to a DC power source or inverter. Doing this
might cause an electrical shock or fire. If you are not sure what kind of power source
you have, contact a qualified electrician.
If water, other liquids, or metal objects get inside the machine, immediately unplug the
machine from the AC power outlet and contact Brother Authorized Service Personnel.
Power Cord Safety:
• Use only the power cord supplied with this product.
• DO NOT allow anything to rest on the power cord.
• DO NOT place the machine where people can walk on the cord.
• DO NOT place the machine in a position where the cord is stretched or strain is
otherwise put on the cord, as it may become worn or frayed.
• DO NOT use the machine or handle the cord if the cord has become worn or frayed.
If unplugging the machine, DO NOT touch the damaged/frayed part.
• Brother strongly recommends that you DO NOT use any type of extension cord.
This product was packaged in a plastic bag. To avoid suffocation, keep this plastic
bag away from babies and children. Do not use the bag in cribs, beds, carriages or
play pens. The bag is not a toy.
AC Adapter Safety
Only use the supplied AC adapter with the unit. Only plug the AC adapter into a power
outlet with voltage that is within the range indicated on Specifications in the User’s
Guide. Failure to do so may result in injury to yourself or others, or damage to the
machine or other property. Brother does not assume any responsibility for any
damage resulting from using an AC adapter other than the one specified.

ix Confidential
DO NOT use the unit near any liquids, for example, near a bath tub, wash bowl,

CHAPTER 2 ERROR INDICATIONS &
TROUBLESHOOTING
1. INTRODUCTION
Troubleshooting is a collection of solution procedures that service personnel should follow if
an error or malfunction occurs in the machine. It is difficult to determine troubleshooting
procedures for all possible problems that may occur in the future. Therefore, this chapter
describes typical problem cases and recovery procedures for these. These will help service
personnel identify and repair other similar defective sections.
1.1 Precautions
Be sure to observe the following precautions to prevent any secondary problems occurring
during troubleshooting:
(1) Be sure to unplug the AC power cord before removing any covers or PCBs, adjusting the
machine, or conducting continuity tests using a tester.
(2) Do not hold the cable when connecting or disconnecting the cable. Be sure to hold the
connector.
(3) Static electricity charged in your body may damage electronic parts.
Before handling the PCBs, touch a metal section of the machine to discharge static
electricity.
When transporting PCBs, be sure to wrap them in conductive sheets.
When replacing PCBs, wear a grounding wrist band and perform replacement on a
conductive mat. Also take care not to touch the conductor sections on the flat cables.
(4) Be sure to always observe all warnings.
(5) After repair is completed, check that the repaired sections, including those removed
once and then remounted, operate normally.
