How this manual is organized

This manual is made up of nine chapters and appendices.

CHAPTER 1 PARTS NAMES AND FUNCTIONS

Contains external views and names of components and describes their functions. Information
about the keys on the control panel is included to help you check operation or make
adjustments.

CHAPTER 2 SPECIFICATIONS

Lists the specifications of each model, which enables you to make a comparison of different
models.

CHAPTER 3 THEORY OF OPERATION

Gives an overview of the scanning and printing mechanisms as well as the sensors, actuators,
and control electronics. It aids in understanding the basic principles of operation as well as
locating defects for troubleshooting.

CHAPTER 4 ERROR INDICATION AND TROUBLESHOOTING

Details error messages and codes that the incorporated self-diagnostic functions display if any
error or malfunction occurs. If any error message appears, refer to this chapter to find which
components should be checked or replaced.

The latter half of this chapter provides sample prob lems that could occ ur in the main sections of
the machine and related troubleshooting procedures. This will help service personnel pinpoint
and repair defective components.

CHAPTER 5 HANDLING DATA HE LD IN THE MACHINE PRIOR TO

REPAIR

Describes how to handle data held in the machine to be repaired.
At the user site, if the machine cannot print F AX data received and left in the machine due to the

printing mechanism defective, the service personnel should instruct the end user to follow the
transfer procedure given in this chapter to transfer the FAX data to another machine before
sending the machine for repair.

At the service site, the service personnel should back up the machine information and user
setting infor mation held in the machin e into an external memor y for restoration after r epair,
using the backup procedure given in this chapter.

CHAPTER 6 DISASSEMBLY/REASSEMBLY AND LUBRICATION

Details procedures for disassembling and rea sse mbli ng t he mac h ine tog et her with related notes.
The disassembly order flow provided enables you to see at a glance the quickest way to get to
component(s) involved.

At the start of a disassembly job, you check th e dis assembly order flow that guides you throu gh
a shortcut to the target components.

This chapter also covers screw tightening torques and lubrication points to which the specified
lubricants should be applied during reassembly jobs.

Confidential

CHAPTER 7 ADJUSTMENTS AND UPDATING OF SETTINGS,

REQUIRED AFTER PARTS REPLACEMENT

Details adjustments and updating of settings, which are required if the head/carriage unit, main
PCB and some other parts have been replaced.

CHAPTER 8 CLEANING

Provides cleaning procedures not covered by the User's Guide. Before starting any repair work,
clean the machine as it may solve the problem concerned.

CHAPTER 9 MAINTENANCE MODE

Describes the maintenance mode which is exclusively designed for the purpose of checks,
settings and adjustments of the machine using the keys on the control panel.

In the maintenance mode, you can update memory (EEPROM: electrically erasable
programmable read-only memory) contents for optimizing the drive conditions of the head/
carriage unit or the paper feed roller and paper ejection roller in the engine unit, if those units
have been replaced , or for se tting the CIS s canner area, for example . You can also customize the
EEPROM according to the sh ipment destination of t he ma chi ne conc erned. In addition, yo u ca n
perform operational checks of the LCD, control panel PCB or sensors, perform a print test,
display the log information or error codes, and modify firmware switches (WSW).

For models with a cordless handset, the maintenance functions dedicated to cordless handsets
are provided.

Appendix 1 Reading Labels

Shows the location of labels put on some parts and describes the coding information for serial
number, head property data, and manufacturing information.

Appendix 2 Firmware Installation

Provides instructions on how to change firmware stored in the flash ROM on the main PCB or
load firmware to a new main PCB from the host PC.

Appendix 3 EEPROM Customizing Codes

Provides instructions on how to set up the EEPROM customizing codes for the various
preferences exclusively designed for each destination. The specified customizing code is stored
in the EEPROM mounted on the main PCB. If the main PCB is replaced, t her efore, you need to
set up the proper customizing code with the machine in the maintenance mode.

Customizing codes customize firmware for individual models, enabling the common firmware
to be used for various models. A list of EEPROM customizing codes comes with the firmware
data provided by Brother Industries.

Appendix 4 Firmware Switches (WSW)

Describes the functions of the firmware switches, which can be divided into two groups: one is
for customizing preferences designed for the shipping destination (as described in Appendix 3)
and the other is for modifying preferences that match the machine to the environmental
conditions. Use the latter group if the machine malfunctions due to mismatching.

Appendix 5 Wiring Diagrams

Provides the wiring diagrams that help you understand the connections between PCBs.

iii

Confidential

Appendix 6 Circuit Diagrams

Provides the circuit diagrams of the MJ PCB and power supply PCB.

Appendix 7 Deletion of User Setting Information

Provides instructions on how to delete user setting information recorded in the machine and
cordless handset(s).

3.2.1 Scanner Mechanism

This mechanism consists of the automatic document feeder (ADF)*, document cover, and
scanner unit (scanner cover).

The scanner unit consists of a scanner top cover, CIS unit, CIS drive assembly, and scanner
base.

The detailed illustration on the nex t page s hows the components making up the ADF: document
pull-in roller, document separation roller, document feed rollers, ADF motor, and document
front and rear sensors.

(1) ADF scanning: Document moves across st ationary CIS unit (Only for mode ls wit h ADF)
Placing a document face down in the ADF activates the document front sensor, switching to

ADF scanning.
The CIS drive mechanism (details below) operates for each scanning command executed. First,

the CIS mot or moves the CIS unit to the white reference film for white level compensation.
Secondly, the ADF motor rotates the document pull-in roller* to pull the document into the
ADF. (*This roller is used in this series of machines in order to pull in documents horizontally
placed.) Thirdly, the CIS motor again moves the CIS unit to the ADF scanning position.

The document separation roller feeds the pages one at a time, starting from the bottom, to the
document feed rollers (1 and 2) , which rota te to move th e page i n a curv e left , up, and r ight. Th e
page is scanned as it passes over the CIS unit. It then leaves the machine face up onto the
ejected document support secti on of the docume nt guide s. The machi ne ejec ts subs equ ent page s

(2) Flat-bed scanning: CIS unit moves under stationary document

The user lifts the document cover, places a page (or open book) face down on the glass plate,
and closes the document cover.

The CIS drive mechanism (details below) operates for each scanning command executed. The
CIS unit first moves to the white reference film for white level compensation. It then moves
right, scanning as it goes. It returns to its home position after the scan.

CIS drive mechanism
The contact image sensor (CIS) unit rides along the CIS rail, driven by the CIS drive belt.

Clockwise motion of the CIS motor move s the unit to the right ; co unterclo ckwise mot ion, to th e
left.

This unit consists of the document illumination LED array, the lens array gathering the light
reflected from the scanned image, the CIS PCB converting the light input to pixel data output,
and the CIS glass.

The CIS unit used in the machine supports color scanning. In scanning color documents, the
CIS unit illuminates them by turning on the red (R), green (G), and blue (B) LEDs alternately.
In scanning monochrome documents, it turns on the green LEDs only.

3.2.2 Printing Mechanism

The printing mechanism co nsists of the following.

 Ink supply and ink jet mechanism (Section 3.2.2.1)
 Head maintenance mechanism (Section 3.2.2.2)
 Carriage drive mechanism (Section 3.2.2.3)
 Paper pulling-in, registration, feeding and ejecting mechanisms (Section 3.2.2.4)

The ink supply mechanism

supplies ink to the head/carriage unit, in which the ink jet

mechanism sprays ink droplets from the head nozzles onto paper.
The major components of the ink supply mechanism (shown on page 3-10) are:

- Ink refill assembly: This secures the ink cartridges and connects them to the corresponding
ink supply tubes.

- Ink supply tubes: These supply the head/carriage unit with ink fed from the ink cartridges via
the ink refill assembly.

The major components of the ink jet mechanism (head/carriage unit shown on page 3-12) are:

- Front end: This is an ink-jet head consisting of piezoelectric plate (PZT), metal plates, nozzle
plate, and head driver.It jets out ink to produce images on paper.

- Back end: This consists of damper assemblies and air vent unit. Each damper assembly
dampens the ink pressure fluctuations in the corresponding ink supply tube and collects air
bubbles that result from pressure changes on the ink.

To keep the optimum head performance, the head maintena nce mechanism

(shown on page 3-

31) uses the rotational torque of the ASF motor* to cap the head nozzles in order to prevent

them from drying up. It also uses the rotational torque of the paper feed motor to purge for
removing air bubbles from the head/carriage unit and wipe off any ink remaining on the head
nozzle surface.

The carriage drive mechanism

(shown on page 3-33) moves the head/carriage unit with a
carriage motor (DC motor) along the recording paper. The CR encoder sensor mounted on the
head/carriage unit scans the CR encoder strip and monitors the current head position relative to
the home position and the current travel speed.

The paper pulling-in, registration, feeding and ejecting mechanisms
motor* and paper feed motor (both are DC motors).

The major components are:

- Paper tray: Recording paper is stored in this tray.

- Paper pull-in rollers (shown on page 3-38):

These rollers pull in paper into the machine.

- Bank ASSY (shown on page 6-93):

This separates paper, sheet by sheet to feed it into the
printing section.

- Jam clear cover (shown on page 3-37):

Opening this cover allows the user to access paper jammed.
It also guides paper pulled in from the paper tray into the
printing section.

- Paper feed roller (shown on page 3-38):

This roller performs paper registration and feeds paper to
the printing section precisely.

- Paper ejection roller (shown on page 3-37):

This roller ejects paper and keeps paper tension tight.

- ASF motor* (shown on page 3-38):

This motor pulls in paper, switches the paper feed operation
modes, and drives the head capping mechanism and
carriage lock mechanism of the maintenance unit.

- Paper feed motor (shown on page 3-38):

This motor feeds recording paper and drives the purge
mechanism, air removing mechanism and head wiper
mechanism of the maintenance unit.

- Clutch gears L and R (shown on page 3-38):

Clutch ge ar L switches the transm ission route of the AS F
motor rotation between the paper pulling-in mechanism and
the head capping & carriage lock mechanisms.

Clutch gear R transmits the rotational torque of the paper
feed motor to the purge gear (for purge, air removing and
head wiper mechanisms).

- ASF rotary encoder: This generates a signal indicating the rotation speed of the

ASF motor shaft. The signal is sent to the controller and
used for controlling the paper pull-in position and speed.

- PF rotary encoder: This generates a signal indicating the rotation speed of the

PF roller gear. The signal is sent to the controller and used
for controlling the paper feed position and speed.

3.2.2.1 Ink supply and ink jet mechanism [ 1 ] Overview

The ink supply and ink-jet mec hanism con sist s of the he ad/car riag e unit, four ink cart ridge s, ink
refill assembly, and four ink supply tubes.

The head/carriage unit scans the surface of the recording paper, jetting out ink supplied through
the ink supply tubes onto the paper to produce images. For further details, see "[ 3 ] Head/

carriage unit" below.

The four ink cartridges (black, yellow, cyan, and magenta) are mounted on the ink refill
assembly. For further details, see "[ 4 ] Ink cartridges" below.

The ink refill assembly secures the ink cartridges and connects them to the corresponding ink
supply tubes. For further details, see "[ 5 ] Ink refill assembly" below.

The ink supply tubes supply the head/carriage unit with ink fed from the ink cartridges via the
ink refill assembly. For further details, see "[ 6 ] Ink supply tubes" below.

[ 2 ] Features

A distinct feature of this machine is the use of ink supply tubes between the ink cartridges and
the head/carriage unit. Relieving the head/carriage unit of the task of carrying heavy ink
cartridges back and forth across the page, the approach generally adopted by other ink-jet
printers, offers the following advantages.

- Smaller unit size--lower height, in particular

- Lower power consu mption

- Lower noise levels

- Lower vibration
During print operation, the ink-jet mechanism inside the head/carriage unit sprays ink droplets

from the head nozzles. The loss of this ink from the head produces a negative pressure that
replenishes the head with ink from the ink tank through the supply tubes.

Note, however, that the above ink flow is only possible when the ink supply tubes are full of
ink. The factory therefore primes the ink supply path by applying strong suction to the head
nozzles with the maintenance unit to suck both air and ink through the ink supply tubes.

Leaving too long interval between this priming and actual use, however, risks air bubbles,
increased viscosity, and other quality issues with the ink in the supply tubes. Before using this
machine for the first time, therefore, this machine automatically replaces the ink supply path
contents with fresh ink using an initial purge, a repeat of this priming operation.

When the machine is on standby, a constant negative pressure (which is produced according to
the difference in height between the head/carriage unit and ink cartridges) is applied to the rear
of the print head, thus preventing ink from leading out of those nozzles.

Note: The above applies only as long as this machine rests on a horizontal surface. Standing
this machine on end or even just tilting it backwards with the print head uncapped risks
overcoming this slight negative pressure preventing ink leakage from the head nozzles.

Piezoelectric ceramic actuators inside the print head convert this ink to droplets sprayed onto
the paper. For further details, see "[ 3 ] Head/carriage unit" below.

3-11

Confidential

[ 3 ] Head/carriage unit

The head/carriage unit con sist s of a fr ont end ( ink-j et hea d) a nd a back e nd (damper and air vent
unit) as shown below.

The front end consists of metal plates laminated together and etched to form ink flow channels.
Piezoelectric ceramic actuators generate the spray pressure. The response of individual front

ends to applied voltages and waveforms varies, however, because of the nature of piezoelectric
materials, fluctuation in manufacturing accuracy, and other factors. The front end therefore
leaves the production line with head property labels giving property data. The manufacturer
writes this prope rty data to the EEPROM on the main PCB incorporating this unit. Based on the
property data of the front end, the processor drives piezoelectric ceramic actuators to insure
consistent performance without fluctuations.

Each assembly has two roles: dampening the ink pressure fluctuations* in the ink supply tube

as the carriage moves and collecting air bubbles that grow in the ink flow path.

* Ink pressure fluctuations: As the head/carriage unit travels, inertia means that the ink remains in the

same place, temporarily raising or lowering the pressure in the right chamber.

- Air vent unit
At regular scheduled in terva ls, thi s vents any air bubbl es that have accumul ate d in the damper

assemblies. The air ven t ro ds in the mai nt enance unit push up the shut-off valves, opening th e
air vent flow paths.

Damping
Without damping, ink pressure fluctuations directly affect the size of ink-jet head droplets,

risking lower print quality.
Each damper assembly has two chambers. The one on the right in the illustration below has a

loose film across its top and serves as a damper. The film immediately flexes in and out in
response to falls and rises in pressure, adjusting the chamber volume to counteract pressure
fluctuations in the ink supply tubes.

This loose film flexes in and out in
response to changes in ink pressure.

Air buffering
Liquid ink contains trace amounts of air. These molecules coalesce into air bubbles as the

piezoelectric ceramic actuators vary t he pressure on the ink in the ink-jet head channel. (See the
illustration on page 3-13.) Removing as many of these bubbles as possible before the ink
reaches the in k-jet head is ess ential to main taining prop er print qualit y. The above ill ustration
shows how the damper assemblies provide air buffers, the chambers on the left, for
consolidating th ese ai r bu bbles a way fro m the ink-j et head and vent fl ow path s for pu r gi ng them

Ink cartridge features
This machine uses four ink cartridges: a black one and three color ones with a slightly lower

capacity. It features horizontal insertion in the ink refill base over plastic needles.
Each cartridge has two ports: one supplying the ink for printing and another intaking air to

replace that ink. Both ports have a disc valve preventing ink leakage. When a cartridge is
mounted over the plastic needles in the ink refill base, these valves are opened to secure flow
paths for both the ink and the air.

(3_06)

These ink cartridges are single-use affairs. There is no provision for refilling them. The design
reduces environment load by using only burnable materials yielding no toxic substances.

Inks
This machine uses dye-based inks for colors and pigment-based ink for black. Using the

pigment-based black ink reduces fuzziness from print character outlines, boosts resolution for
black dots, and produces clearer images on plain paper.

- Ink foam and its case

Pushing the ink cartridges into the ink refill case

until they click secures them and forces the
cartridges' ink supply ports into close contact with the ink refill base to prevent ink leakage.
Pressing down the cartridge release lever

pops the ink cartridge out of the ink refill case.

The ink from the ink cartridges flows through the ink flow channels provided in the ink refill
base into the ink supply tubes. As the ink level in an ink cartridge drops, the pressure inside
falls, drawing air in the ink cartridge.

The ink cartridge detection sensors

detect ink car tridges inserted wh en the machine powe r is

ON.
The ink empty sensors

detect ink remaining in the ink cartridges loaded. An ink empty sensor
actuator blocking the light beam to an ink empty sensor indicates that there is ink in the ink
cartridge. When ink runs low, the actuator moves out of the beam, activating the sensor ("Ink
near-empty") and showing the "Ink low" message.

If any of the ink cartridges is replaced with the one having different ink volume when the
machine power is OFF, the corresponding ink cartridge detection sensor and ink empty sensor
issue different sig nal s when the power is turned ON next time so that the control ler prompt s th e
user to reload the ink cartridge.

At the back of the ink refill case is an ink foam

that absorbs any ink that leaks from the air
intake ports of the ink cartridges loaded when the machine is tilted during transportation or in
storage, preventing ink spread in the machine.

[ 6 ] Ink supply tubes

These are made of low-density polyethylene (LDPE) providing a highly impermeable barrier
against air ingress and drying out of the ink during extended periods of nonuse. This material is
also soft and highly flexible to better withstand the sharp and frequent bending associated with
high-speed head operation repeatedly over extended periods.

- Pump switching uni t
This switches the application target of the negative pressure generated by the tube pump

between the head cap for black ink, the one for color ink, and the air vent cap. Usually the
pump switching un it is switc hed to the openin g tube to the at mospheri c air so that the pr es sure
in the head caps and air vent cap is equal to the normal atmospheric pressure.

- Air vent cap and rods
The air vent cap and rods remove air bubbles trapped in the damper assemblies in the back

end of the head/carriage unit.
During air venting with the tube pump, the air vent cap fits tightly over the ai r vent uni t in the

head/carriage unit so that the negative pressure applies to the air vent unit. Pushing up the air
vent rods opens the shut-off valves inside the air vent unit, removing air bubbles trapped in
the damper assemblies. (For the air vent unit, see Section 3.2.2.1, [ 3 ].)

- Head wiper
As the head/carriage unit moves, this wipes off any ink remaining on the head nozzle surface.

- Tube pump
A roller squeezes the main drain tube looped inside, forcing their contents toward the ink

absorber box and creating negative pressure.
