complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions:

(1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.

This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the end user is encouraged to try to correct the interference by one or more of the following measures:

•Reorient or relocate the receiving antenna.

•Increase the separation between the equipment and receiver.

•Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.

•Consult the dealer or an experienced radio/TV technician for help.

Important

A shielded interface cable should be used to ensure compliance with the limits for a Class B digital device. Changes or modifications not expressly approved by Brother Industries, Ltd. could void the user’s authority to operate the equipment.

SAFETY INFORMATION

■ Caution for Laser Product (WARNHINWEIS fur Laser drucker)

CAUTION:	When the machine during servicing is operated with the cover open, the
	regulations of VBG 93 and the performance instructions for VBG 93 are
	valid.
CAUTION:	In case of any trouble with the laser unit, replace the laser unit itself. To
	prevent direct exposure to the laser beam, do not try to open the enclosure
	of the laser unit.
ACHTUNG:	Im Falle von Störungen der Lasereinheit muß diese ersetzt werden. Das
	Gehäuse der Lasereinheit darf nicht geöffnet werden, da sonst
	Laserstrahlen austreten können.

<Location of the laser beam window>

■Additional Information

When servicing the optical system of the machine, be careful not to place a screwdriver or other reflective object in the path of the laser beam. Be sure to take off any personal accessories such as watches and rings before working on the machine. A reflected beam, though invisible, can permanently damage the eyes.

Since the beam is invisible, the following caution label is attached on the laser unit.

■Safety Precautions

Listed below are the various kinds of “WARNING” messages included in this manual.

WARNING

There are high voltage electrodes inside the machine. Before you clean the inside of the machine or replace parts, make sure that you have turned off the power switch and unplugged the machine from the AC power outlet.

DO NOT handle the plug with wet hands. Doing this might cause an electrical shock.

The fuser unit becomes extremely hot during operation. Wait until it has cooled down sufficiently before replacing consumable items. DO NOT remove or damage the caution label located on or around the fuser.

xiii	Confidential

WARNING

DO NOT use flammable substances or any type of spray to clean the inside or outside of the machine. Doing this may cause a fire or electrical shock.

If the machine becomes hot, blows smoke, or generates obscure odor, immediately turn off the power switch and unplug the machine from the AC power outlet.

If metal objects, water or other liquids get inside the machine, immediately turn off the power switch and unplug the machine from the AC power outlet.

Caution

Lightning and power surges can damage this product! We recommend that you use a quality surge protection device on the AC power line, or unplug the machine during a lightning storm.

CHAPTER 1 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.

1.1Precautions

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)Electronic devices are sensitive to static build up; make sure that you touch a metal portion of the machine to discharge yourself before accessing the PCBs.

Handle PCBs with care when repairing them.

(4)Follow the warning by all means.

The fuser unit becomes extremely hot during operation. Wait until it has cooled down sufficiently before replacing consumable items. DO NOT remove or damage the caution label located on or around the fuser.

(5) Verify again that the repaired portion works properly.

1-1	Confidential

1.2Initial Check

Check the following items before attempting to repair the machine.

■Operating Environment

(1)Put your machine on a flat, stable surface such as a desk that is free of vibration and shocks.

(2)Use the machine in a well-ventilated room; use the machine within the following ranges of temperature and humidity: temperature between 10°C and 32.5°C (50°F to 90.5°F), and the relative humidity is maintained between 20% and 80%.

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

■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.

(Refer to “2.6 Paper”, Reference 1 of the Service Reference Manual.)

(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) 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 optical surfaces such as the scanner window, lenses, the reflection mirror and the protection glass may cause the print image to be light.

•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 failures.

If condensation has occurred, leave the machine for at least 2 hours to allow it to reach room temperature.

If the drum unit is unpacked soon after it is moved from a cold place to a warm room, condensation may occur inside the unit which may cause incorrect images. Instruct the end user to allow the unit to come to room temperature before unpacking it. This will take one or two hours.

1-2	Confidential

(2)Cleaning

Use a soft dry cloth.

CAUTION:

DO NOT use flammable substances or any type of spray to clean the inside or outside of the machine. Doing this may cause a fire or electrical shock.
