SAFETY INFORMATION
Laser Safety (110-120V Model only) This printer is certified as a Class 1 laser product under the US Department of Health and Human Services (DHHS) Radiation Performance Standard according to the Radiation Control for Health and Safety Act of 1968. This means that the printer does not produce hazardous laser radiation. Since radiation emitted inside the printer is completely confined within the protective housings and external covers, the laser beam cannot escape from the machine during any phase of user operation.
CDRH Regulations (110-120V Model only) The Center for Device and Radiological Health (CDRH) of the US Food and Drug Administration implemented regulations for laser products on August 2, 1976. These regulations apply to laser products manufactured from August 1, 1976. Compliance is mandatory for products marketed in the United States. The label shown below indicates compliance with the CDRH regulations and must be attached to laser products marketed in the United States.
The label for Chinese products MANUFACTURED: JULY 2001 BROTHER CORP. (ASIA) LTD. BROTHER BUJI NAN LING FACTORY Gold Garden Industry, Nan Ling Village, Buji, Rong Gang, Shenzhen, China. This product complies with FDA radiation performance standards, 21 CFR Subchapter J. C

INSTALLING THE UPDATE DATA TO THE FACSIMILE MACHINE
If you want to update the current program stored in the flash ROM of the main PCB to the newer version or after you replace the main PCB, install the update program onto the flash ROM. The program installation requires a PC/AT-compatible computer (which is capable of running MS-DOS or its compatible OS).
Connecting the facsimile machine to your computer (1) Make sure that your computer is turned off. (2) Make sure that the machine's power cord is unplugged from a wall socket. (If the machine has a power ON/OFF switch, make sure that the switch is turned off.) (3) Connect the parallel interface cable to the parallel port on the back of the machine and secure it with the lock wires. (4) Connect the other end of the interface cable to the printer port of your computer and secure it with the two screws. (5) While pressing the 5 key on the machine's control panel, plug the machine's power cord into a wall socket (or turn on the power ON/OFF switch if the machine has the switch). (6) Check to see that the following pattern displays on the LCD. If it does not display, go back to step (2) above.

SETTING ID CODES TO FACSIMILE MACHINES
Brother facsimile machines are assigned unique ID codes (character strings) at the factory. If you replace the main PCB of the machine, the machine will lose its assigned ID code so that it will not be identified by the connected PC*. You need to assign a unique ID code (character string) to the machine according to the procedure given here. For models covered by this manual, set serial numbers given to individual machines as ID codes.
(*ID codes are essential when more than one machine is connected to a single PC via USB.)
Connecting the facsimile machine to your PC (See the illustration on page II-1.) (1) Make sure that your PC is turned off. (2) Make sure that the machine's power cord is unplugged from a wall socket or other power source. (3) Connect the interface cable to the parallel interface port on the back of the facsimile machine and secure it with the lock wires. (4) Connect the other end of the interface cable to the printer port of your PC and secure it with the two screws. (5) Plug the machine's power cord into a wall socket or other power source. (6) Turn on your PC. Operating procedure (1) On your PC, run the ID setting utility. Follow the instructions shown on the PC's screen and enter the 9-digit serial number (e.g., G01012345) printed on the nameplate labeled to the back of the facsimile machine as an ID code. Then press the Enter key. The ID setting utility will transmit the ID code data from your PC to the facsimile machine and then it will terminate. The facsimile machine will automatically return to the standby mode. (2) To check whether the entered character string (ID code) is correct, make the machine enter the maintenance mode (refer to CHAPTER V, Section 1) and then press the 1 key twice (Subsection 3.5). The facsimile machine will print out a Configuration List. At the right top of the list, "SER.#: BROXXXXXXXXX" is printed. (3) Check that the character string entered in step (2) is printed in "XXXXXXXXX." If it is OK, press the 9 key twice to exit from the maintenance mode. If something other than that is printed in XXXXXXXXX, check the connection between the PC and facsimile machine and go back to step (1).

MECHANISMS
The machine is classified into the following mechanisms: SCANNER MECHANISM LASER PRINTING MECHANISM - ADF mechanism - Document scanning mechanism - Paper pick-up and registration mechanism - Print process mechanism (consisting of charging, exposing, developing, and transferring processes) with paper feeding mechanism - Heat-fixing mechanism with paper feeding mechanism - Paper ejecting mechanism
SENSORS AND ACTUATORS
III - 2
2.1
Scanner Mechanism This mechanism consists of the following: - document tray ASSY which consists of a document chute and document tray, - automatic document feeder (ADF) unit which consists of a document feed roller ASSY, document ejection roller ASSY, ADF motor, and document front and rear sensors, and - scanner unit which consists of a scanner top cover, CCD unit, CCD drive mechanism, CCD HP sensor, and scanner base. For details about the sensors, refer to Section 2.3.
III - 3
This scanner mechanism supports a dual scanning system. (1) If you set documents with their faces up on the document chute and start the scanning operation, the ADF motor rotates so that the document feed roller ASSY feeds those documents into the ADF unit, starting from the top sheet to the bottom, page by page. Each document curves downwards and turns to the right so as to advance above the CCD unit, and then it is fed out to the document tray with the document ejection roller ASSY. This way, documents move above the CCD unit being kept in a stationary position. (2) If you open the scanner unit, put a sheet of document (or put a bound book opened) on the glass of the scanner top cover, close the scanner unit, and start the scanning operation, then the CCD drive mechanism will be driven. That is, the CCD motor rotates and its rotation will be transmitted via the gear train to the CCD drive belt. The CCD unit, which is supported and guided by the CCD rail, is secured to the CCD drive belt. Clockwise and counterclockwise rotations of the CCD motor move the CCD unit to the right and left, respectively. In this scanning system, the CCD unit moves horizontally beneath a document being kept in stationary position. The CCD unit contains a charge coupled device (CCD) image sensor. The cold-cathode fluorescent lamp illuminates a document and the reflected light of the scanned image data is transmitted via the mirrors into the lens which reduces the scanned data so as to form the image on the CCD.
III - 4
2.2
Laser Printing Mechanism
2.2.1
Paper pick-up and registration mechanism
III - 5
At the 1st stage, the controller drives the main motor without energizing the solenoid so that the paper feed roller simply idles. At the 2nd stage, the controller energizes the solenoid so that the paper feed roller no longer rotates and the paper pick-up roller starts rotating to pick up paper into the machine, a sheet at a time. After the leading edge of the pulled-in paper passes through the manual insertion sensor actuator, the paper is further fed for the specified time length. Accordingly, the leading edge will reach the paper feed roller where the paper skew will be eliminated. At the 3rd stage, the controller deenergizes the solenoid to rotate the paper feed roller for feeding paper to the transfer block in the drum unit. When the leading and trailing edges of the paper pass through the registration sensor actuator, the sensor signals them to the controller. According to those signals, the controller may determine the first print position on the paper.
2.2.2
Print process mechanism
III - 6
The print process unit works with laser beam, electrical charges, and toner. The graph below shows the transition of electrical charge on the surface of the laser-sensitive drum through the four processes: charging, exposing, developing, and transferring processes.
III - 7
2.2.3
Heat-fixing mechanism
As the paper passes between the heater roller and the pressure roller in the heat-fixing unit, the heater roller fuses the toner on the paper. The controller monitors the internal resistance of the heater thermistor to keep the surface temperature of the heater roller constant by turning the halogen heater lamp on and off.
III - 8
2.2.4
Paper ejecting mechanism
Exit roller
Outer chute Jam sensor actuator
(Front) Paper ejection roller Paper ejection sensor actuator Paper
Heat-fixing unit
After the paper passes through the heat-fixing process, it will be ejected from the heat-fixing unit by the paper ejection roller. If the leading edge of the paper pushes down the actuator of the paper ejection sensor, the sensor signals the start of paper ejection. If the trailing edge has passed through the sensor actuator, the sensor signals the completion of paper ejection. If the jam sensor actuator will not be pushed up within the specified period after the leading edge of the paper pushes down the paper ejection sensor actuator, then the controller will interpret such an event as a paper jam inside the heat-fixing unit and display a jam error on the LCD. The paper will be turned over along the outer chute and ejected onto the main cover by the exit roller.

DISASSEMBLY/REASSEMBLY
To prevent the creation of secondary problems by mishandling, observe the following precautions during maintenance work. (1) Unplug the power cord from the power outlet before accessing parts or units inside the machine. When having access to the power supply, be sure to unplug the power cord from the power outlet. (2) When servicing the optical system of the laser printing unit, be careful not to place screwdrivers or other reflective objects in the path of the laser beam. Be sure to take off any personal accessories such as wrist watches and rings before working on the printer. A reflected beam, though invisible, can permanently damage your eyes. (3) If the machine has been printing, allow the heat-fixing unit (inside this unit is a heater roller) sufficient time to cool down before starting maintenance jobs. It is HOT! (4) Be careful not to lose screws, washers, or other parts removed for parts replacement. (5) Do not remove gears from the document feed roller ASSY or document ejection roller ASSY if at all possible. Once removed, they will become unusable and new gears will have to be put back in. (6) When using soldering irons and other heat-generating tools, take care not to damage the resin parts such as wires, PCBs, and covers. (7) Before handling the PCBs, touch a metal portion of the machine to discharge static electricity; otherwise, the electronic parts may be damaged due to the electricity charged in your body. (8) When transporting PCBs, be sure to wrap them in conductive sheets such as aluminum foil. (9) Be sure to reinsert self-tapping screws correctly, if removed. Unless otherwise specified, tighten screws to the following torque values: Taptite, bind B and cup B Taptite, cup S Other screws M3: M4: M3: M3: M4: 0.7 N·m 0.8 N·m 0.8 N·m 0.7 N·m 0.8 N·m
n Safety Precautions
(10) When connecting or disconnecting cable connectors, hold the connector bodies not the cables. If the connector has a lock, always slide the connector lock to unlock it. (11) Before reassembly, apply the specified lubricant to the specified points. (Refer to Section 2 in this chapter.) (12) After repairs, check not only the repaired portion but also that the connectors and other related portions function properly before operation checks.

Reassembling Notes · · Take care not to mistake the upper LF roller ASSY (gray) for the lower LF roller ASSY (black). When setting the document sensor PCB back into place, do not push it down straight, but first fit the PCB in the large latch and then fit it in the small latch (see the illustration given on page IV13). Be sure to route the document sensor harness through the three harness guides so that it will not interfere with the document rear sensor actuator. (See the illustration given on page IV-13.) Reinstall the ADF motor with its connector side facing up. (See the illustration given on page IV12.) Reinstall the ADF side covers so that the tabs of the ADF side plates become fitted inside the ribs provided on the ADF side covers. (See the illustration given on page IV-11.) When reinstalling the ADF side cover R, be sure to route the document sensor harness, ADF motor harness, and grounding wire between the boss and the ADF side cover R. (See the illustration given on page IV-11.) When reinstalling the ADF unit, first set the ADF support onto rear pin "x" of the ADF unit, set the ADF unit back into place, set the other ADF support onto front pin "y," then secure those ADF supports with two screws "c." (See the illustration given on page IV-10.) When connecting the ADF motor harness, document sensor harness, and grounding wires to the relay PCB, route them as shown below.
