Power Cord Safety:

• This product is equipped with a 3-wire grounded plug. This plug will only fit into a grounded power outlet. This is a safety feature. DO NOT attempt to defeat the purpose of the grounded plug.

• DO NOT pull on the middle of the AC power cord; pulling on the middle may cause the cord to separate from the plug. Doing this might cause an electrical shock.

• Only use the power cord supplied with this product (for certain models only).

• DO NOT use any undesignated cables (or optional devices). It may cause a fire or injuries. Installation must be performed properly according to the user's guide.

• This product should be positioned so that nothing pinches or constricts the power cord.

• DO NOT allow anything to rest on the power cord.

• DO NOT place this product where people may step on the cord.

• DO NOT place this product in a position where the cord is stretched or strained, as it may become worn or frayed.

• DO NOT use the product if the power cord is frayed or damaged. Doing so may cause an electrical shock or fire.

• Brother strongly recommends that you DO NOT use any type of extension cord.

• DO NOT drop any metallic hardware or any type of liquid on the power plug of the product. It may cause an electrical shock or a fire.

DO NOT put a toner cartridge or a toner cartridge and drum unit assembly into a fire. It could explode, resulting in injuries.

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 product. Doing so could cause a fire or electrical shock. Instead, use only a dry, lint-free cloth.

DO NOT attempt to operate this product when a paper jam or stray pieces of paper are inside the product. Prolonged contact of the paper with the fuser unit could cause a fire.

DO NOT use a vacuum cleaner to clean up scattered toner. Doing this might cause the toner dust to ignite inside the vacuum cleaner, potentially starting a fire. Carefully clean the toner dust with a dry, lint-free soft cloth and dispose of it according to local regulations.

CHAPTER 2 ERROR INDICATIONS AND

TROUBLESHOOTING

1. INTRODUCTION

Troubleshooting is the countermeasure procedures that the service personnel should follow if an error or malfunction occurs with the machine. It is impossible to anticipate all of the possible troubles which may occur in future and determine the troubleshooting procedures, so this chapter covers some sample troubles. However, those samples will help the service personnel pinpoint and repair other defective elements.

1.1 Precautions

Be sure to observe and follow all the precautions to prevent any secondary problems from happening during troubleshooting.

(1) Always turn OFF the power and unplug the power cable before removing any covers or

PCBs, adjusting the machine and so on. If you need to take voltage measurements with the power switched on, take the greatest of care not to receive an electric shock.

(2) When connecting or disconnecting cable connectors, make sure that you hold the

connector body and not the cables.

(3) Static electricity charged in your body may damage electronic parts. Before handling the

PCBs, touch a metal portion of the machine to discharge static electricity charged in your body. When transporting PCBs, be sure to wrap them in conductive sheets. When replacing the PCBs, put on a grounding wrist band and perform the job on an antistatic mat. Also take care not to touch the conductor sections on the flat cables.

(4) Follow the warning by all means.

Warning

Hazard labels as shown below are attached to the machine. Fully understand the descriptions on the hazard labels and observe them during troubleshooting. Take extreme care not to remove or damage the hazard labels.

2-1

Confidential

Warning

DO NOT use any flammable spray or flammable solvent such as alcohol,

benzine, or thinner in or around the machine. Otherwise a fire or electric shock may result.

(5) Check again that the portions and parts repaired or removed during the repair work

function properly when the repair is completed.

A certain interface or function could be set to invalid to serve the needs of customers. Ask sales representative if this is the case before performing the check.

1.2 Checks before Commencing Troubleshooting

Check the following items before attempting to repair the machine.

 Operating environment

(1) The machine is placed on a flat, stable surface.

(2) The machine is used in a clean environment where the temperature is between 10°C

(50°F) and 32°C (89.6°F) and the relative humidity is maintained between 20% and 80%.

(3) Ensure the machine is not exposed to direct sunlight, excessive heat, moisture, or dust.

(4) Keep the machine horizontal when you carry it. To prevent injuries when moving or lifting

this machine, make sure to use at least two people.

 Power supply

(1) The AC input power supply described on the rating plate of the machine should be within

±10% of the rated voltage.

(2) The AC input power supply is within the regulated value.

(3) The cables and harnesses are connected correctly.

(4) The fuses are not blown.

 Paper

(1) A recommended type of paper is being used.

(2) The paper is not damp.

(3) The paper is not short-grained paper or acid paper.

 Consumable parts

(1) The drum unit (including the toner cartridge and toner box) is installed correctly.

 Others

(1) Condensation

When the machine is moved from a cold place into a warm room, condensation may occur inside the machine, causing various problems as listed below.

• Condensation on the surface of optical devices such as the lens, reflecting mirror, and protection glass, etc., may cause light print image.

• If the exposure drum is cold, the electrical resistance of the photosensitive layer is increased, making it impossible to obtain the correct contrast when printing.

• Condensation on the charge unit may cause corona charge leakage.

• Condensation on the plate and separation pad may cause paper feed problems.

If condensation has occurred, leave the machine for at least two hours to allow it to reach room temperature.

If the drum unit is unpacked soon after it is moved to a warm room from a cold location, condensation may occur inside the unit which may cause printing failure. Leave the drum unit for one or two hours until it reaches room temperature, and then unpack it.

(2) Low temperature

The motor may not drive normally under the low temperature environment. This is due to there being too much load to drive each unit. In this case, increase the room temperature.

2-3

Confidential

 Cleaning

Use a soft dry lint-free cloth.

Warning

DO NOT use any flammable spray or flammable solvent such as alcohol, benzine,

or thinner to clean the machine. DO NOT use these articles near the machine.
