3.1 OVERVIEW Host Centronics parallel interface* Control panel Fax Control Section USB interface Printer Control Section Print data Line NCU Scanner - CIS unit - Scanner motor Ink jet printer unit - Ink jet print head unit - Carriage motor - Carriage ASSY - Purge unit Paper feeding mechanism - Paper feed motor Power supply *Not provided in the MFC3200C/FAX1800C.
3.
3.2.1 Scanner Mechanism 3.2.1.1 Document feeding and ejecting mechanism This mechanism consists of the document stacker, automatic document feeder (ADF), document feed roller ASSY, document ejection roller ASSY, and document sensors. (For details about the sensors, refer to Subsection 3.2.3.
3.2.2 Ink Jet Printing Mechanism 3.2.2.1 Paper pulling-in, registration, feeding, and ejecting mechanisms The paper pulling-in, registration, feeding, and ejecting mechanisms are driven by a single paper feed motor located at the left side of the main chassis via the gear train. (See the illustration given on the next page.) First, the paper feed motor rotates clockwise (when viewed from the output gear). The rotation is transmitted to the PF roller gear that rotates paper feed roller.
Gear 31MF Gear shaft 17 PF roller gear R ASF roller unit Gear 39 Paper feed roller Gear 25 ASF-purge switching gear 23 ASF/purge idle gear PF roller gear Paper feed motor 3 -5
3.2.2.2 Ink jet printing and capping mechanisms (1) Print head unit This machine uses drop-on-demand ink jet printing. Each of the right and left print heads has an ink-jet unit that has a pair of nozzle columns for two color inks. A nozzle column consists of 75 nozzles, 75 channels covered with piezoelectric ceramic (PZT), a manifold, and filter. As illustrated below, the pair of nozzle columns is staggered.
If the controller issues a print command, a biased voltage will be applied to all electrodes formed on the surface of the piezoelectric ceramic so that each actuator will be distorted as shown with broken lines. If the electrodes on a target channel are deenergized according to drive signals, then the associated piezoelectric ceramic actuator returns to the previous form so that the ink in the manifold will be vacuumed out to the channel.
(3) Head caps Shown below is a head cap mechanism that prevents the nozzles of the print heads from drying up when they are not in use. Upon completion of printing, the carriage travels to the right and moves the head cap holder provided on the purge unit to the right together. In the head cap holder is a head cap unit which is supported with a lift lever.
3.2.2.3 Purging mechanism The purge mechanism is driven by the paper feed motor located at the left side of the main chassis. As described in Subsection 3.2.2.1, the motor rotation is transmitted to the ASF/purge idle gear at the right side of the main chassis. Engaged with the ASF/purge idle gear, the ASF-purge switching gear 23 works as a clutch gear.
During printing: The ASF-purge switching gear 23 is not engaged with purge bevel gear A (but engaged with gear 25 in the ASF gear train). During purging: The ASF-purge switching gear 23 is engaged with purge bevel gear A. When the motor rotation is transmitted to the purge unit, its counterclockwise rotation will drive the purge cam and its clockwise rotation, the pump switching unit (when viewed from the output gear of the motor).
The purge cam is so designed that: - the carriage lock pops out to lock the carriage before purging and pops in before cleaning with the head wiper (see the illustration below), - the pump works to draw out ink from each of the four head nozzles and drain it to the ink absorber felts, and - the head wiper comes out to clean the nozzle surface (see the illustration below).
3.2.2.4 Carriage drive mechanism The carriage motor controls horizontal motion. The motor rotation is transmitted via the motor pulley to the timing belt. The carriage, which is supported and guided by the carriage rail, is secured to the timing belt. Clockwise and counterclockwise rotations of the carriage motor move the carriage to the right and left, respectively.
3.2.3 Sensors and Actuators This machine has the following sensors and thermister.
These photosensors (except the ink empty sensor that is a reflection type) are a photointerrupter consisting of a light-emitting diode and a light-sensitive transistor. Each of them has an actuator separately arranged as shown on the next page.
Location of Sensors and Actuators NOTE: The hook switch (not shown above) is provided in the MFC3200C/FAX1800C.
3.3 CONTROL ELECTRONICS 3.3.1 Configuration The hardware configuration of the facsimile machine is shown below.
