PREFACE
This publication is a Service Manual covering the specific ations, construction, theory of operation,
and maintenance of the Brother facsimile equipment. It includes information required for field
troubleshooting and repair--disassembly, reassembly, and lubrication--so that service personnel will
be able to understand equipment function, to rapidly repair the equipment and or der any necessary
spare parts.
To perform appropriate m aintenance so that the f acsim ile equipment is always in best condition for
the customer, the service personnel must adequately understand and apply this manual.
This manual is made up of six chapters and appendices.

SAFETY INFORMATION
Laser Safety (110-120V Model only)
This printer is certif ied as a Class 1 laser produc t under the US Department of Health and Hum an
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 com pletely 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 Adm inistration
implemented regulations f or laser products on August 2, 1976. These regulations apply to laser
products manufactured fr om August 1, 1976. Compliance is mandatory for products mark eted 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.

1. INSTALLING THE UPDATE DATA TO THE FACSIMILE EQUIPMENT
If the program version is updated or the main PCB is r eplaced, install the update program onto the
flash ROM of the main PCB.
The program inst allation requires a PC/AT-compatible c omputer (which is capable of r unning MSDOS or its compatible OS).
Connecting the facsimile equipment to your computer
(1) Make sure that the equipment's power cord is unplugged from a wall socket.
(2) Make sure that your computer is powered off.
(3) Connect the interface cable to the parallel interf ace port on the back of the equipment and
secure it with the lock wires.
(4) Connect the other end of the interface cable to the printer por t of your com puter and sec ure it
with the two screws.
(5) Power on your computer.
(6) Plug the equipment's power cord into a wall socket.

Installing the update data onto the flash ROM of the facsimile equipment
NOTE: The following is an installation procedure example on a PC that is running Windows 95/98.
(1) Copy the update data and transfer utility onto the desired directory of the hard disk.
e.g., C:\UPDATE
(2) Click the Start button, point to Program s, and then click MS-DOS Prompt to open an MS-
DOS window.
(3) Type the drive letter where the update data and transfer utility are located. In the above
example, type C:\ from the command line and press the ENTER key.
Then type CD UPDATE and press the ENTER key.
(4) Check that your computer is connected with the facsimile equipment correctly.
(5) To start the transfer utility transmitting the update data to the flash ROM of the facsimile
equipment, type the following:
ICEN filename /b
Then press the ENTER key.
During downloading, the equipment beeps intermittently.
Upon completion of the downloading, the equipment beeps continuously.
NOTE: If the facsimile equipment cannot return to the standby state after completion of
downloading, turn the power off and on.

2.1 Scanner Mechanism
2.1.1 Document feeding and ejecting mechanism
This mechanis m consists of the document s tacker, automatic docum ent feeder (ADF), docum ent
ejection roller ASSY, and document sensors. (For details about the sensors, refer to Section 2.3.)
If the operator sets documents on the document stacker and starts the scanning operation, the
scanner motor rotates so that the ADF (which consists of the separation roller and ADF parts) feeds
those documents into the equipment, starting from the bottom sheet to the top, page by page.
Each document advances with the docum ent f eed roller ASSY to the scanner , and then it is fed out
of the equipment with the document ejection roller ASSY.
2.1.2 Scanner
The scanner uses a contact image sens or (CIS) unit which consists of an LED array illuminating
documents, a self-focus lens array collecting the reflected light, a CIS PCB carrying out
photoelectric conversion to output picture elem ent data, and a cover glass on which a docum ent
advances. W hen the doc ument passes between the document pr ess ur e bar and the c over glass , it
is scanned.

2.2 Laser Printing Mechanism
2.2.1 Paper pulling-in, registration, feeding, and ejecting mechanism
III - 4
Paper pulling-in and registration mechanism
The paper pulling-in and registration m echanism consis ts of the pull-in roller gear (incorporated in
the multi-purpose sheet f eeder), planetary gear system, paper f eed solenoid, s olenoid lever, c lutch
release lever, and registration sensor. (For the details about the sensor, refer to Section 2.3.)
If the main motor rotates clockwise, the rotation is transmitted to the intermediate gear of the
planetary gear system. As the intermediate gear rotates, the pull-in roller drive gear also rotates
since the clutch gear is locked by the solenoid lever and the clutch release lever. Ac cordingly, the
pull-in roller in the multi-purpos e sheet feeder rotates to pull in paper into the equipm ent, a s heet at
a time.
If the paper feed solenoid is retracted and the clutch release lever is operated according to the c am
profile of the pull-in roller gear s o as to releas e the clutch gear, the clutc h gear rotates and the pullin roller drive gear does not rotate. In this way, the clutch gear switches the transmission of the
motor rotation to the pull-in roller drive gear on and off.
The solenoid on/off timing and the clutch release lever timing allow this mechanism to pull in a
sheet and register it against the registration roller.
Paper feeding and ejecting mechanism
If the main motor rotates clock wise, the rotation is transmitted via the gear train to the drum drive
gear, heater roller drive gear, and paper ejection roller drive gear.
After the paper passes through the heat-fixing process, it will be ejected onto the paper tray.
If the leading edge of the paper pushes up the actuator of the paper ejection sensor, the
photosensor becomes opened, s ignaling the start of paper ejec tion. If the trailing edge has pass ed
through the sensor actuator, the sensor becomes closed, signaling the completion of paper
ejection. Then, the main motor stops rotation.
III - 5
2.2.2 Print process mechanism
The print process unit works with laser beam, electrical charges, and toner. The graph below
shows the transition of electrical c harge on the surface of the las er-sensitive drum thr ough the five
processes: charging, exposing, developing, transferring, and erasing processes.
III - 6
2.2.3 Heat-fixing mechanism
As the paper passes between the heater roller and the press ure roller in the heat-fixing unit, the
heater roller fuses the toner on the paper.

2.3 Sensors and Actuators

• Document front sensor which detects the presence of documents.
• Document rear sensor which detects the leading and tr ailing edges of pages to tell the control
circuitry when the leading edge of a new page has reached the starting position and when the
scan for that page is over.
• Top cover sensor which detects whether the top cover is closed.
• Registration sensor which detects the leading and trailing edges of paper, which allows the
controller to determine the registration timing and check paper jam.
• Paper ejection sensor which detects whether the recording paper goes out of the equipment.
• Toner sensor which detects whether there is toner or a toner cartridge is loaded.
• Toner thermister which detects the ambient temperature of the toner cartridge.
• Heater thermister which detects the temperature of the heater roller of the fixing unit.
• Hook switch* which detects whether the handset is placed on the handset mount.
