    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.

  • Page 48

    [ 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 49

    [ 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.

  • Page 50

    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 51

    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 53

    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 54

    ---------------------------------------- [ 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 55

    -------------------------- [ 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.

(See the illustration below.) The maintenance unit has the following mechanisms. - Head capping mechanism (See page 3-27.) - Carriage lock mechanism (See...

    - Pump switching unit 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.

  • Page 64

    [ 3 ] Mechanisms constituting the head maintenance mechanism (1) Head capping mechanism The ASF motor drives the 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 65

    (3) Purge mechanism The paper feed motor drives the purge mechanism. The counterclockwise rotation of the paper feed motor drives the purge cam that aligns the pump switching unit with either the black or color ink drain position. Next, the paper feed motor reverses to activate the tube pump, producing negative pressure to drain the air and old ink from the head nozzles and channels into the ink absorber box.

  • Page 66

    (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 head cap unit fits 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 67

    (4) Air removing mechanism Other two positions of the purge cam shift two slide cams--one for black ink, the other for color inks, producing vertical motion of a single air vent rod for black ink and three air vent rods for color ink, respectively.

  • Page 75

    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.

  • Page 76

    Height adjustment of the head/carriage unit For optimal image printing, a pair of slider cams mounted on the head/carriage unit switches the height of the head/carriage unit against the CR guide rail and support chassis between two levels--2.3 mm (for thick paper and envelops) and 1.6 mm (for other types of paper) in order to bring the optimum distance between the head nozzle surface and paper.
