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 problems that could occur 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 HELD 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 FAX 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 information held in the machine into an external memory for restoration after repair, using the backup procedure given in this chapter.

CHAPTER 6 DISASSEMBLY/REASSEMBLY AND LUBRICATION

Details procedures for disassembling and reassembling the machine together 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 the disassembly order flow that guides you through 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.

ii	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 setting the CIS scanner area, for example. You can also customize the EEPROM according to the shipment destination of the machine concerned. In addition, you can 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, therefore, 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).

Avoid touching the shiny (coated) side of photo paper. Load photo paper with the shiny side facing down.

Avoid touching either side of transparencies because they absorb water and perspiration easily, and this may cause decreased output quality. Transparencies designed for laser printers/copiers may stain your next document. Use only transparencies recommended for inkjet printing.

You can only print on both sides of the paper with PC printing using Windows.

3.2.1Scanner 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 next page shows the components making up the ADF: document pull-in roller, document separation roller, document feed rollers, ADF motor, and document front and rear sensors.

For further details on the sensors, see Section 3.2.3.

Models with ADF offer two types of scanning: ADF scanning and flat-bed scanning. They automatically switch to the former at the start of a scan operation if the document front sensor inside the ADF detects a document. Models without ADF offer only flat-bed scanning.

3-6	Confidential

(1) ADF scanning: Document moves across stationary CIS unit (Only for models with 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 motor 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 rotate to move the page in a curve left, up, and right. The page is scanned as it passes over the CIS unit. It then leaves the machine face up onto the ejected document support section of the document guides. The machine ejects subsequent pages under this one to preserve the document page order.

(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 moves the unit to the right; counterclockwise motion, to the 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.

3.2.2Printing Mechanism

The printing mechanism consists 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 maintenance 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 are driven by the ASF 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.

*ASF motor: Auto Sheet Feeder motor

3-8	Confidential

- 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 gear L switches the transmission route of the ASF 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 mechanism consists of the head/carriage unit, four ink cartridges, 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 consumption

-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 consists of a front end (ink-jet head) and a back end (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 property 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.

Ink spray function

The head employs drop-on-demand ink-jet printing.

Print commands to the drive circuit apply a bias voltage to the layer electrodes on the piezoelectric ceramic surface stretching the elements perpendicular to that surface. Drive signals removing this voltage for specific channel electrodes allow the piezoelectric elements to return to their original shape, sucking ink into the corresponding channels*. Reapplying the bias voltage stretches the elements once again, applying pressure to the ink, spraying it from the head nozzle. The ink drop hits the paper on the platen, forming a dot.

Back end components and their main roles

-Damper assemblies

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 intervals, this vents any air bubbles that have accumulated in the damper assemblies. The air vent rods in the maintenance unit push up the shut-off valves, opening the air vent flow paths.

3-15	Confidential

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.

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

Left chamber

(DamperFunc)

Air buffering

Liquid ink contains trace amounts of air. These molecules coalesce into air bubbles as the piezoelectric ceramic actuators vary the 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 ink-jet head is essential to maintaining proper print quality. The above illustration shows how the damper assemblies provide air buffers, the chambers on the left, for consolidating these air bubbles away from the ink-jet head and vent flow paths for purging them at regular scheduled intervals.

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.

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.

3-17	Confidential

Ink near-empty/ink empty detection

The ink refill assembly has four ink empty sensors (photosensors of transparent type) that monitor the ink levels with sensor actuators inside the ink cartridges.

Float (InkEmptySensor_2)

Attached to one end of the sensor actuator is a float. When there is ink in the cartridge, buoyancy lifts the float, rotating the sensor actuator about a pivot near the center of the actuator to block the light beam to the ink empty sensor, indicating that there is ink.

As the ink level in the ink cartridge drops, however, the float falls, eventually moving the sensor actuator out of the beam.

Light hitting the sensor outputs the "ink near-empty" signal to the controller that shows the "Ink low" message and activates a firmware counter tracking ink usage during ink-jet printing, purges, and other operations. When this counter reaches a predetermined limit, the firmware regards it as "ink empty" and shows the "Cannot Print" message to prompts the user to replace it.

-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 cartridges inserted when the machine power 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 signals when the power is turned ON next time so that the controller prompts the 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.

3.2.2.2 Head maintenance mechanism

[ 1 ] Overview

The head maintenance mechanism, which keeps the optimum head performance, consists of the maintenance unit and the ink absorber box. (See the illustration below.)

The maintenance unit has the following mechanisms.

-Head capping mechanism (See page 3-24.)

-Carriage lock mechanism (See page 3-24.)

-Purge mechanism (See page 3-25.)

-Air removing mechanism (See page 3-27.)

-Head wiper mechanism (See page 3-28.)

The ink absorber box absorbs the ink sucked out by purge operations.

-Cap lift cam and its gear

These parts transmit the rotational torque of the ASF motor transmitted via the clutch gear L to the head cap holder. (See [ 4 ] "Power transmission route to the head maintenance mechanism and motor rotational direction.")

-Head cap unit

When the power is off or the machine is not printing, the head cap unit fits tightly over the print head to prevent the head nozzles from drying up and to seal the head nozzles for purge operations to suck up old ink.

-Head cap holder

This lifts up the head cap unit to fit it tightly over the print head to seal the head nozzles. (The had cap holder is driven by the ASF motor.)

-Carriage lock

This is a part of the head cap holder. It locks the head/carriage unit in its home position so that the head cap unit protects the head nozzles.

-Purge gear and purge bevel gear

These gears transmit the rotational torque of the paper feed motor via the clutch gear R to the planetary arm. (See [ 4 ] "Power transmission route to the head maintenance mechanism and motor rotational direction.")

-Planetary arm

This switches the rotational torque of the paper feed motor (transmitted via the purge gear and purge bevel gear) to the pump switching unit or tube pump depending on the direction of paper feed motor rotation.

-Purge cam

This rotating cam drives the pump switching unit, the air vent rods, and the head wiper. Each drive position of the purge cam is detected by the purge cam switch. (See Section 3.2.3.)

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 unit is switched to the opening tube to the atmospheric air so that the pressure 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 air vent unit 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.
