    3.2.1 Scanner 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, document ejection rollers, ADF motor, and document front and rear sensors.

  • Page 58 (1) ADF scanning: Document moves across stationary CIS unit Placing a document face up 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.

    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 61: Ink Supply And Ink Jet Mechanism

    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 62: 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 63: 3 ] Head/Carriage Unit

    [ 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 64 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 65 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 67 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.

    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 74 - 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 75: 3 ] Mechanisms Constituting The Head Maintenance Mechanism

    [ 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 76 (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 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 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 78 (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 85 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 86 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.

    3.2.2.4 Paper pulling-in, registration, feeding and ejecting mechanisms These mechanisms are driven via a gear train by two motors--paper feed motor located on the left side of the engine chassis and ASF motor in the right rear corner. (See the illustration on the next page.) The following illustration is a cross-sectional view of the machine viewed from the right.
  • Page 89 Power transmission routes of the ASF motor and paper feed motor The rotational torque of the ASF motor is transmitted to the ASF/maintenance drive gear which always meshes with the clutch gear L, as described in Section 3.2.2.2, [ 4 When the mode switching lever is in the left position (normal SF or high-speed feed mode), the clutch gear L also meshes with the ASF changeover gear which transmits the ASF motor rotation via a gear train to the paper pull-in rollers.
  • Page 90 Normal SF and high-speed feed mode Normal SF mode 1st stage The ASF motor rotates clockwise (when viewed from the output gear side) and its rotational torque is transmitted to the ASF/maintenance drive gear that is always connected via the idle gear 16 to the clutch gear L. When the mode switching lever is placed in the left position, the clutch gear L also meshes with the ASF changeover gear.
  • Page 91 Other controls Paper feed position and speed control A PF encoder disk with the resolution of 300 dpi (0.084 mm pitch) is mounted on the PF roller gear L. The PF encoder sensor uses it 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.
