  • Page 55 3.2.1 Scanner Mechanism 3.2.1.1 Document feeding and ejecting mechanism This mechanism consists of the document support, automatic document feeder (ADF), document feed roller, document ejection roller ASSY, and document sensors. (For details about the sensors, refer to Section 3.2.3.) Placing documents face down on the top cover and starting the scanning operation activate the scanner motor so that the ADF (consisting of the document pull-in roller, nip piece, separation roller and ADF parts) feeds the documents into the machine, starting from the bottom (first page), page by page.

  • Page 56: Printing Mechanism

    3.2.2 Printing Mechanism 3.2.2.1 Paper pulling-in, registration, feeding and ejecting mechanisms These mechanisms are driven by a single paper feed motor located at the left of the engine unit via a gear train. (See the illustration on the next page.) The following illustration is a cross-sectional view of the machine viewed from the right.
  • Page 57 First, the paper feed motor rotates counterclockwise (when viewed from the output gear side). The motor rotation passes to the PF roller gear L and, via the ejection idle gear, the ejection roller gear to rotate the paper feed and ejection rollers in the reverse direction. At the right end of the paper feed roller is the PF roller gear R which is always engaged with the clutch gear and the idle gear L.
  • Page 58 The outer circumference of the PF roller gear L functions as a 300 dpi (0.084 mm pitch) encoder disk which the PF encoder sensor uses to generate a signal indicating the gear rotation speed--in other words, the paper feed roller speed--to the controller for use in controlling paper feed position and speed.

  • Page 59: Ink Supply And Ink Jet Mechanism

    3.2.2.2 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 60 [ 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 61 [ 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). The front end consists of metal plates laminated together and etched to form ink flow channels. (See illustration.) Piezoelectric ceramic actuators generate the spray pressure.
  • Page 62 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 matter from the ink.

  • Page 64 n Back end Shutoff valve Damper ASSY (Color) Air vent unit (A part of head/carriage unit) Air vent rods Air vent cap (A part of maintenance unit) Damper ASSY (Black) Back end components and their main roles - Damper assembly This has two roles: dampening the ink pressure fluctuations** in the tubes as the carriage moves and collecting air bubbles that result from pressure changes on the ink.
  • Page 65 Damping Without damping, ink pressure fluctuations directly affect the size of ink-jet head droplets, risking lower print quality. The damper structure for black differs from that for the colors (C, M, and Y) because black has twice nozzles used for each color, meaning higher ink flow rates and bigger pressure fluctuations. - Color dampers The three color damper assemblies each have two chambers.
  • Page 66 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 generated by the piezoelectric ceramic actuators repeatedly expand and contract any air bubbles, causing them to gradually grow larger as the ink pressure changes repeatedly expand and contract them.
  • Page 67 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.

    "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 69 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 71 Air flow path Ink flow path Ink refill assembly components and their main roles - Ink refill base This holds the ink cartridges and feeds ink from them to the ink supply tubes. - Cartridge clamp springs These force the ink cartridges into close contact with the ink cartridge joint to prevent ink leakage. - Joint head This lifts the disc valves S and D, allowing ink to flow out of the ink cartridges and air to flow in.

  • Page 72: 6 ] Ink Supply Tubes

    [ 6 ] Ink supply tubes These are made of an elastomer 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.

  • Page 73: Head Maintenance Mechanism

    3.2.2.3 Head maintenance mechanism [ 1 ] Maintenance mechanism components The head maintenance mechanism consists of the maintenance unit and the ink absorber box. (See the illustration below.) The maintenance unit has the following functions. - Locking the head/carriage unit - Capping the head nozzles to prevent them from drying up (See page 3-24.)
  • Page 74 - Planetary arm This switches power to the tube pump and pump switching unit depending on the direction of paper feed motor rotation. - Bevel gear This transmits the power from the clutch gear to the planetary arm. - Tube pump A roller squeezes the ink drain tubes looped inside, forcing their contents toward the ink absorber box and creating negative pressure.

  • Page 75: 3 ] Head Capping Mechanism

    [ 3 ] Head capping mechanism When the power is off or the machine is not printing, this mechanism fits the head caps tightly over the print head to prevent the head nozzles from drying up and to keep dust off the print nozzle surface.

  • Page 76: 4 ] Purge Mechanism

    [ 4 ] Purge mechanism This mechanism draws its power from the paper feed motor on the left side of the main chassis. Gears between paper feed motor and maintenance unit As described in Section 3.2.2.1, the motor drives the PF roller gear L that rotates the paper feed roller.
  • Page 77 When the head/carriage unit travels from the left to right to reach the purge position, a tab on the carriage rear panel pushes the purge lever to the right (left in the illustration). The clutch gear spring pushes the clutch gear to the right, away from idle gear L, to mesh with the purge gear. At the purge position, therefore, the maintenance unit transmits the paper feed motor rotation to the bevel gear.

  • Page 79 (1) Carriage lock Driving the purge cam pushes the carriage lock up and down. During the purge operation, the carriage lock pops out and locks the head/carriage unit to align ink-jet units with the mating head caps. After the purge operation, but before cleaning with the head wiper starts, the purge cam pulls in the carriage lock and releases the head/carriage unit.
  • Page 80 (3) Head wiper 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 Purge cam (4) Switching pump The pump switching unit switches the negative pressure from the pump between the black head nozzles, the color head nozzles, and the air vent rod unit.
  • Page 81 (5) Removing air 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 expels air trapped in the manifolds.

  • Page 85: Carriage Drive Mechanism

    3.2.2.4 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 (1/25.4 inch pitch) transmits the carriage motor rotation to the carriage. Clockwise motor rotations move the carriage to the right; counterclockwise ones to the left.
  • Page 86 Adjusting 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.
