  • Page 58 (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.
  • Page 59 3.2.2 Printing 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.

  • Page 60: 1 ] Overview

    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 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.

  • Page 61: 2 ] Features

    [ 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.

  • Page 62: 3 ] Head/Carriage Unit

    [ 3 ] Head/carriage unit The head/carriage unit consists of a front end (ink-jet head) and a back end (buffer 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.
  • Page 63 Front end Front end components and their main roles - Piezoelectric plate Applying a voltage stretches the plate, serving as the actuator for spraying ink. Consisting of thin piezoelectric plates laminated together, this plate can be driven even by a low voltage. - Filter This removes foreign materials from the ink.
  • Page 64 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*.

  • Page 66 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.
  • Page 67 [ Tip: Air bubble growth ] Liquid ink contains trace amounts of air. The amount varies with the pressure on the ink because increasing the pressure raises the ink's ability to absorb air from its surroundings and lowering the pressure forces the ink to give up some of this air. The ink pressure fluctuations caused by the piezoelectric ceramic actuators repeatedly expand and contract any air bubbles, growing them larger gradually.
  • Page 68 [ Tip: What's so bad about air bubble growth? ] Pressure fluctuations do not affect the volume of a liquid (ink), but Boyle's Law says that the volume of a gas (air) varies with the pressure on it. The main issue with air bubbles in the ink flow path is their damping effect, absorbing the pressure from the piezoelectric ceramic actuators and thus degrading ink-jet performance.

  • Page 69: 4 ] Ink Cartridges

    "Pigment-based ink" Previous Brother machines used only dye-based inks. This one switches to a pigment-based ink for black only, reducing fuzziness from print character outlines, boosting resolution for black dots, and producing clearer images on plain paper.
  • Page 70 Ink cartridge components and their main roles - Disc valve S A plastic needle in the refill base opens this valve to supply air to the ink cartridge. Removing the ink cartridge closes this valve to prevent leakage due to ink backflow. - Disc valve D A plastic needle in the refill base opens this valve to allow ink to flow out of the ink cartridge.

  • Page 72: 6 ] Ink Supply Tubes

    Ink refill assembly components and their main roles - Ink refill case - Cartridge lock levers - Ink refill base - Ink tube joints - Ink cartridge sensors (on the ink cartridge PCB) - Ink absorber felts Inserting the ink cartridges into the ink refill case and securing them with the cartridge lock levers forces the cartridges' ink supply ports into close contact with the ink refill base to prevent ink leakage.

  • Page 73: Head Maintenance Mechanism

    3.2.2.2 Head maintenance mechanism [ 1 ] Overview The head maintenance mechanism 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 3-25.)
  • Page 74 - Purge gear and purge bevel gear These gears transmit the power from the clutch gear (detailed in [ 4 ] later) to the planetary arm. - Planetary arm This switches power to the tube pump or pump switching unit depending on the direction of paper feed motor rotation.

  • Page 75: 3 ] Mechanisms Constituting The Head Maintenance Mechanism

    [ 3 ] Mechanisms constituting the head maintenance mechanism (1) Head capping mechanism When the power is off or the machine is not printing, this mechanism fits the head cap unit (which contains two head caps) tightly over the print head to prevent the head nozzles from drying up and to keep dust off the head nozzle surface.
  • Page 76 (2) Carriage lock mechanism This mechanism locks the head/carriage unit to prevent the head nozzles from getting out of the head cap unit accidentally due to external vibration or impact when the machine is not printing, when the power is off, or during transport. Driving the purge cam causes the carriage lock to pop up in order to lock the head/carriage unit when the head caps are tightly pressed against the ink-jet units.
  • Page 77 (3.1) Switching pump The pump switching unit switches the application target of the negative pressure generated by the pump between the head cap for black ink, the one for color ink, and the air vent cap. When the purge cam is in a head capping position and the carriage lock fits the head cap unit tightly over the print head, 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 returns to the normal atmospheric pressure.
  • Page 78 (4) Head wiper mechanism After the purge operation, the purge cam pushes up the head wiper, wiping off any ink remaining on the head nozzle surface as the head/carriage unit moves from right to left. Maintenance unit Head wiper (3_11) Purge cam 3-27 Confidential...
  • Page 79 (5) Air removing mechanism Another position of the purge cam shifts the slide cams, producing vertical motion of the air vent rods. Pushing up the air vent rods opens the shut-off valves inside the air vent unit of the head/carriage unit. Simultaneously adding negative pressure from the tube pump removes air trapped in the damper assemblies.

    [ 4 ] Purge mechanism details This mechanism draws its power from the paper feed motor on the left side of the engine chassis. Power transmission route from paper feed motor to maintenance unit The paper feed motor drives the PF roller gear L that rotates the paper feed roller. At the right end of the roller (left in the illustration because the view is from the rear) is the PF roller gear R which always meshes with the clutch gear.

    3.2.2.3 Carriage drive mechanism The head/carriage unit, which integrates the print head unit and carriage, is supported and guided by the CR guide rail and CR support chassis. The CR timing belt transmits the carriage motor rotation to the head/carriage unit. Clockwise motor rotations move the head/carriage unit to the right; counterclockwise ones to the left.
  • Page 86 Adjusting the print head angle relative to carriage For optimal image printing, the print head nozzle array must be perpendicular to the head/carriage unit's line of travel. Manufacturing limitations, however, make perfect alignment impossible during mass production. The angle must be adjusted at the individual machine level. The following describes this adjustment mechanism's components and their roles.
