Part 1: Safety and Precautions BJC-6000 1. SAFETY PRECAUTIONS 1.1 Moving Parts Be careful not to get your fingers, hair, clothing, or accessories caught in the moving parts of the printer. The moving parts are driven either by the carriage motor or paper feed motor. The carriage motor-related moving parts include the carriage, carriage belt, and carriage ribbon-cable.
Part 1: Safety and Precautions BJC-6000 1.2 Ink Stains 1.2.1 Ink paths Be careful not to touch the ink paths. Ink on hands could stain the printer, work table, or clothes. The ink paths include the BJ cartridge ink tank outlet, the BJ cartridge ink filters and nozzles, the maintenance jet receiving section, the head caps, the wipers, and the waste ink absorber.
Part 1: Safety and Precautions BJC-6000 1.2.2 Ink mist The BJ cartridge ejects ink onto the paper during printing. After the printer is used for a long period or used heavily, part of the ink ejected from the nozzles, or ink mist bouncing back from the paper could accumulate and contaminate the platen, front cover, as well as the periphery of the purge unit. Carefully wipe off the ink mist with a dampened soft cloth so that hands or clothing will not be stained by contaminated parts during servicing.
Part 1: Safety and Precautions BJC-6000 1.3 Live Electrical Parts When the printer is plugged into a wall outlet, the power supply unit of the printer is live, even if the power is switched off with the POWER button. Be careful not to get an electric shock or damage sensitive elements if you are checking a live printer with the cover removed.
Part 1: Safety and Precautions BJC-6000 2. MACHINE PRECAUTIONS 2.1 BJ Cartridges 2.1.1 BJ cartridge handling Do not unpack the BJ cartridge until you are ready to use it. Before installing the BJ cartridge in the printer, carefully remove the head cap which protects the nozzles, the protective tape, and the protective tank. To prevent the nozzles or other ink paths from clogging, never touch or wipe the nozzles or other ink outlets with your bare hands or tissue paper.
Part 1: Safety and Precautions BJC-6000 2.1.2 Automatic capping When the printer is turned off with the POWER button, it automatically caps the BJ cartridge's nozzles to protect them as well as to prevent ink leakage. If the AC cable is unplugged from a wall outlet before the printer is turned off with the POWER button, the nozzles will not be automatically capped. In this case, plug in the AC cable again, turn on the printer, and then turn it off with the POWER button.
Part 1: Safety and Precautions BJC-6000 2.2 Ink Tanks 2.2.1 Unpacking the ink tank Do not unpack the ink tank until you are ready to use it.

Figure 1-6 Unpacking the Ink Tank 2.2.2 Ink tank handling If the joint of the BJ cartridge connecting to the ink tank supply piece is contaminated, suction of ink into the BJ cartridge could fail.
Part 1: Safety and Precautions BJC-6000 2.3 Printer Handling 2.3.1 Spurs Take care not to bend the tips of the spurs. The tips of the spurs make contact with printed paper and are contaminated with ink, but due to their small surface contact area, the tips, cleaned by the spur cleaners, will not stain the printed paper.
Part 1: Safety and Precautions BJC-6000 2.3.2 Damage due to static electricity Static electricity may be generated by your clothes rubbing against each other and may accumulate in your body. If you touch electrical elements, the discharge of static electricity could damage them or change their electrical characteristics. For this reason, never touch the sensor contacts or the printer's BJ cartridge contacts.
Part 1: Safety and Precautions BJC-6000 2.3.3 Ink leakage prevention When you turn off the printer using the POWER button, the printer moves the carriage to the capping position, caps the nozzles, and locks the carriage in position with the lock arm. If electric power is not available to the printer, during transportation for example, this automatic capping and locking is not available.
Part 1: Safety and Precautions BJC-6000 3. NOTES ON SERVICING 3.1 EEPROM Data The printer keeps track of the total sheets printed by each BJ cartridge configuration (Black/Color and Photo/Color) and the total waste ink amount and stores that information in the EEPROM (IC 602) on the logic board. Observe the following precautions during servicing: 1) Before servicing You can check the EEPROM data with a test print.
Part 1: Safety and Precautions BJC-6000 3.2 Static Electricity Static electricity may be generated by your clothes rubbing against each other and may accumulate in your body. If you touch electrical elements, the discharge of the static electricity could damage them or change their electrical characteristics. To prevent damage due to such electrostatic discharge, ground yourself by touching a metal fitting which is grounded before disassembling or otherwise servicing the printer.
Part 1: Safety and Precautions BJC-6000 3.3 Disassembly and Reassembly Disassembly and reassembly must be done according to the relevant parts catalog, which illustrates the step-by-step procedures to be followed.

These signals consist of the drive control signals that cause ink to be discharged from the head nozzles, and the thermal control signal that controls the head temperature to ensure constant ink discharge.
Part 4: Technical Reference BJC-6000 b) Color/Photo BJ cartridge control The Color/Photo BJ cartridge has 144 (48 x 3) nozzles. Each nozzle has two heater boards in an array, large and small, one in front, the other in the rear. The front and rear two heaters will be controlled to provide multi-drop driving, with both driven simultaneously to discharge a large drop, or with only the small one driven to discharge a small drop.
Part 4: Technical Reference BJC-6000 1.4.2 Print drive method The head can be driven in one of the following six drive methods: 180 x 180 dpi (large dot), 360 x 360 dpi (large dot), 360 x 360 dpi (multi-drop drive), 360 x 360 dpi (largelarge dot), 720 x 720 dpi (small dot), and 1440 x 720 dpi (small dot) with the drive method differing depending on whether printing is in the forward or reverse direction.
Part 4: Technical Reference BJC-6000 b) 180 x180 dpi (large dot, forward direction) control mode In this mode, only 8 out of 16 nozzles in one block will be heated. This allows the carriage to travel faster than it would if all 16 nozzles were heated, resulting in faster printing. c) 360 x 360 dpi (large dot, forward direction) control mode In this mode, the nozzles that would have been heated simultaneously in a) multidrop drive will be heated sequentially one at a time from No.16 through No.1.
Part 4: Technical Reference BJC-6000 g) Reverse direction print mode In the reverse direction print mode, printing takes place similarly, except that the nozzles are heated in the reverse order. As such, the signals (ODD/EVEN, BENB) that determine the heating order are driven with timing reversed from that used in forward direction printing.
Part 4: Technical Reference BJC-6000 1.5 Power-Off Sequence Flowchart Beeper sounds once I/F busy set Indicator blinks Error reset When BJ cartridge or ink tank is replaced while replacing cartridge • No cartridge • Capping in progress • While replacing cartridges, neither of the two cartridges is in place.
Part 4: Technical Reference BJC-6000 2. FIRMWARE 2.1 Interface This printer's interface supports compatible mode, nibble mode, and ECP mode in compliance with the IEEE 1284 Parallel Interface Standards. The compatible mode is a uni-directional data transfer protocol similar to the Centronics interface conventional protocol. The nibble mode and ECP mode are bi-directional data transfer protocols used to transfer to the host computer the status data, including the device ID, printer status, etc.
Part 4: Technical Reference BJC-6000 2.1.2 Nibble mode The Nibble mode is used to transfer data to the host computer. It is in this mode that the printer sends the printer status data to the host computer. Four input control signals are used for data transfer with handshake between the PtrClk and HostBusy signals. 1) The host computer, ready to receive data, causes HostBusy to go low.
Part 4: Technical Reference BJC-6000 2.1.3 ECP mode The ECP mode allows data to be transferred bi-directionally between the printer and host computer. This mode also allows 2 byte data transfer to provide faster data transmission and reception. It is for this reason that ECP mode is suitable for transferring large amounts of data. In response to the fall of the ReverseRequest signal, the direction of the data bus switches from forward data transfer mode to reverse data transfer mode.
Part 4: Technical Reference BJC-6000 2.2 Print Control 2.2.1 Print mode The printer adjusts the carriage action and paper feed action according to the installed cartridges, selected print media, printing quality, print data, etc. to ensure high quality printing free from diffusion and density variations.

Part 4: Technical Reference BJC-6000 2.3 Automatic Printing Position Alignment Function This printer features the automatic printing position alignment function so that the difference between the installed left and right BJ cartridges in vertical/horizontal printing position and bi-directional printing position will be automatically adjusted.
Part 4: Technical Reference BJC-6000 2.4 Pause Between Scanning This printer features pause between-scanning to prevent bleeding and white clouding be caused by differences in characteristics between color ink and black ink. This function allows the border between the color ink and black ink to be detected during internal print data processing so that, when detected, an appropriate pause will be imposed on each print mode and color to prevent bleeding.
Part 4: Technical Reference BJC-6000 3. PRINTER'S MECHANICAL SYSTEM 3.1 Overview The printer's mechanical system is comprised of the BJ cartridges, carriage unit, purge unit, paper-feed unit, and drive switching unit. The following describes each of these units: Carriage Unit Paper Feed Unit Drive Switching Unit Purge Unit BJ Cartridges Figure 4-13 Printer's Mechanical System 3.1.
Part 4: Technical Reference BJC-6000 3.1.3 Purge unit The purge unit, driven by the paper feed motor, is comprised of the wiper, pump, cap, and carriage lock unit. The wiper unit keeps the BJ cartridge head face in good condition to ensure high quality printing while the suction function ensures that the ink in the nozzle can be easily discharged. When not in use, the unit protects the BJ cartridge with its cap and secures the carriage by locking it in place. 3.1.
Part 4: Technical Reference BJC-6000 3.2. BJ Cartridge 3.2.1 Construction of the Black BJ cartridge The Black BJ cartridge has a 160-nozzle multi-drop bubble jet head and a detachable black ink tank. a) Air path Keeps the pressure inside the ink tank constant with the external atmospheric pressure. b) Ink chamber Loaded with black ink. The ink in the ink chamber will be supplied via the sponge to the BJ head. A sensor is used to check for ink. c) Ink sponge Saturated with black ink.
Part 4: Technical Reference BJC-6000 3.2.2 Construction of the Color and Photo BJ cartridges Color and Photo BJ Cartridges come equipped with a multi-drop bubble jet head comprised of 48 nozzles for each of the three colors, for a total of 144 nozzles, and have separate, detachable ink tanks, one for each color. a) Air path Keeps the pressure inside the ink tank constant with the external atmospheric pressure. b) Ink chamber Loaded with ink.
Part 4: Technical Reference BJC-6000 3.2.3 Construction of the bubble jet head unit a) Bubble jet nozzle Ink absorbed in the ink sponge will be filtered through the mesh ink filter, then fed to the bubble jet nozzles via ink pipes. When the head drive current passes through a heater board in a nozzle, the ink will boil, producing bubbles. These small bubbles eventually coalesce into one large bubble.
Part 4: Technical Reference BJC-6000 b) Nozzle arrangement The bubble jet nozzles are lined up vertically at 1/360 inch pitch in one column. Color and Photo BJ cartridge have 8 dummy nozzles separating the nozzles of each color.

Part 4: Technical Reference BJC-6000 d) Cartridge identification This printer uses 5 signals, HCLOCK (Pin 13), HDATA (Pin 9), HLAT (Pin 19), HRSTX (Pin 29), and DIR (Pin 28) to communicate serially with the bubble jet head to identify the installed BJ cartridge and the head rank. Bubble jet head heater characteristics are classified into 24 types according to the variations associated with the manufacturing process. The printer compensates for these variations to provide optimum control of ink discharge.
Part 4: Technical Reference BJC-6000 3.3 Purge Unit 3.3.1 Function of the purge unit The purge unit keeps the BJ cartridge nozzles in good working condition to ensure high printing quality. The unit is designed to provide both capping and cleaning functions. a) Capping The capping function presses the purge unit's cap against the print head face to prevent the nozzles from drying and becoming contaminated. During capping, a cam is actuated to lock the carriage in place.
Part 4: Technical Reference BJC-6000 3.3.2 Construction of the purge unit Wiper Release Unit Wiper Unit Cap Unit Carriage Lock Unit Purge Drive Gear Pump Unit Air Valve Unit Figure 4-20 Purge Unit a) Purge drive gear Receives the power of the feed roller driven by the paper feed motor via the drive switching unit to drive the pump. The pump roller's position is detected by the pump sensor. b) Wiper unit Operates when the carriage travels back and forth.
Part 4: Technical Reference BJC-6000 d) Pump The pump is a tube pump type that applies the pressure of turning rollers to the ink tube to create negative pressure for sucking ink. Applying the pressure of two turning rollers alternately allows greater control over the amount of ink to be sucked, and helps to reduce the size of the pump unit.
Part 4: Technical Reference BJC-6000 3.4 Paper Feed Unit 3.4.1 Functions of the paper feed unit a) Paper feed function This printer has two paper supply methods, using the auto-sheet feeder in automatic paper feed mode, or the manual feed slot. The built-in auto-sheet feeder, driven by the paper feed motor and loaded with paper, supplies paper into the printer automatically. Also, feeding of postcards and envelopes can be performed automatically without operating a mechanical paper selection lever.
Part 4: Technical Reference BJC-6000 b) Paper thickness adjustment The clearance between the head face of the BJ cartridge and the paper varies with the thickness of the paper. Smaller clearance improves the printing quality however, paper contacting the head face risks spoiling print quality or damaging the BJ cartridge head face. This printer is equipped with a 2-position paper thickness selector to provide constant paper clearance. The carriage shaft is supported by means of an eccentric bearing.
Part 4: Technical Reference BJC-6000 3.4.2 Construction of the paper feed unit This printer's paper feed unit is mechanically comprised of the pick-up unit, paper feed unit, and the paper eject unit.
Part 4: Technical Reference BJC-6000 To manually feed paper, the user must insert the paper into the manual feed slot until the paper end sensor detects it. In the manual paper feed mode, the pick-up guide changes its position for the paper to pass through a different path from that in which the auto-sheet feeder is used. As a result, manual paper feed mode is possible even when the auto-sheet feeder is loaded with paper.
Part 4: Technical Reference BJC-6000 3.5 Carriage Unit 3.5.1 Functions of carriage unit a) Mounting BJ cartridges The carriage secures BJ cartridges mechanically in place and connects them via the carriage ribbon cable to the control board. When the printer is powered off, the carriage will be locked in the capping position. b) Driving the carriage The carriage, driven by the carriage motor, travels along the horizontal width of the paper using the carriage belt.
Part 4: Technical Reference BJC-6000 3.5.2 Construction of the carriage unit Carriage Ribbon Cable BJ Cartridge Mount Home Position Edge Carriage Lock Position Edge Signal Contacts Carriage Belt Carriage Motor Figure 4-26 Carriage Unit a) BJ cartridge mount BJ cartridges are secured to the carriage with the BJ cartridge lock lever.
Part 4: Technical Reference BJC-6000 c) BJ cartridge maintenance By controlling the carriage position, wiping and cleaning operations will be performed on the BJ cartridge. During capping, as the carriage travels left to right, the notch on the carriage causes the purge section wiper flag to move, raising the wiper and capping the cartridge. When the carriage travels right to left, the cartridge is wiped clean, after which the hook unit on the carriage unlocks the wiper latch, lowering wiper.
Part 4: Technical Reference BJC-6000 d) Paper feed motor drive switching unit Depending on the carriage position, the drive switching unit switches the paper feed motor's drive power over to drive the purge unit or the auto-sheet feeder. The slide arm that travels in sync with the carriage action controls the operation of the selector flag.
Part 4: Technical Reference BJC-6000 4 PRINTER'S ELECTRICAL SYSTEM 4.1 Overview The electronics of this printer can be functionally divided into the control unit and the power supply unit. The control section converts the input data from the host computer into print signals or printer control signals, and drives the BJ cartridges and motors while monitoring all the sensors.
Part 4: Technical Reference BJC-6000 4.2 Control Unit 4.2.
Part 4: Technical Reference BJC-6000 4.2.2 Logic Components RESUME Switch LED Cover Sensor CN403 CN404 CN603 CN401 ROM CN602 CN402 POWER Switch Printer Controller Motor Driver Buzzer EEPROM DRAM MPU TH201 Paper End Sensor Figure 4-33 Control Board a) Printer controller The printer controller incorporates the interface controller, print head controller, buffer controller, DRAM controller, stepping motor controller and I/O ports and operates in sync with the 25MHz external clock input.
Part 4: Technical Reference BJC-6000 Buffer controller Writes the received data into the DRAM's receive buffer automatically, controls the remaining receive buffer capacity, reads the print buffer automatically, and clears the data that has been read. The print buffer manages two separate areas for the 2 heads.
Part 4: Technical Reference BJC-6000 A/D converter Detects the following analog signals: Internal temperature analog signal from the thermistor on the control board. Head temperature analog signal from the temperature sensors inside the BJ cartridge. Ink chamber ink detection analog signal from the ink sensor. Density detection signal from the print position sensor for printing position compensation.
Part 4: Technical Reference BJC-6000 4.3 Power Supply Unit 4.3.
Part 4: Technical Reference BJC-6000 5. DETECTION FUNCTIONS 5.1 Detection with Sensors This printer has the following sensors detect the printer's status. Cover Sensor Paper End Sensor Internal Temperature Sensor Pump Sensor Print Position Sensor Home Position Sensor Ink Sensor Figure 4-35 Sensor Positions 5.1.1 Home position sensor This photointerruptor-type sensor detects the chassis' home position edge and capping position edge to find the carriage's position.
Part 4: Technical Reference BJC-6000 5.1.4 Ink sensor Consists of an LED and photosensor to optically check for ink in the ink chamber part of the ink tank. At the ink chamber bottom is a protrusion that acts as a prism. If ink is present in the chamber, the refraction rates of ink and the prism resin are nearly equal, producing less reflection.
Part 4: Technical Reference BJC-6000 5.1.8 Head temperature sensor Located inside the print head in the BJ cartridge, this sensor detects the head temperature so that the printer can stop printing when this sensor detects an abnormal temperature rise in the head as a head temperature abnormal error. The diode sensor output varying with the head temperature is detected as a varying voltage, so the incoming analog values are converted into digital values by the built-in A/D converter. 5.
