  • Page 15: Installing The Update Data To The Facsimile Machine

    The program installation requires a PC/AT-compatible computer running MS-DOS, Windows 95, or Windows 98. For the MFC3200C/FAX1800C, it requires Windows 98, Windows Me, or Windows2000. MFC3100C/MFC580 Setting up the facsimile machine and your PC (1) Make sure that your PC is turned off.
  • Page 16 Installing the update data onto the flash ROM of the facsimile machine NOTE: The following is an installation procedure example on a PC that is running Windows 98. (1) Copy the update data and transfer utility onto the desired directory of the hard disk. e.g., C:\UPDATE (2) Click the Start button, point to Programs, and then click MS-DOS Prompt to open an MS-DOS window.
  • Page 17 MFC3200C/FAX1800C CAUTION: During installation, do not turn the power off, interrupt downloading, or download invalid data. If you do so, downloading will fail so that you need to replace the main PCB of the facsimile machine with a new one and download update data again. The failure PCB is no longer usable. Installing the printer driver to your PC If the MFC3200C/FAX1800C is first connected to your PC, no printer driver is installed to your PC.
  • Page 18 (1) Get "Filedg32.exe" utility and save it onto the desk top of your PC. (2) Double-click the “Filedg32” icon. The Filedrgs window will appear. (3) Drag and drop the firmware update file (ex. 1800usaC.dat) onto the printer icon (e.g., "Brother FAX1800C") in the Filedrgs window. During downloading, the facsimile machine beeps intermittently.

  • Page 19: Setting Id Codes To Facsimile Machines

    2.2 SETTING ID CODES TO FACSIMILE MACHINES Brother facsimile machines are assigned unique ID codes (character strings) at the factory. If you replace the main PCB of the machine, the machine will lose its assigned ID code so that it will not be identified by the connected PC*.
  • Page 20 (1) On your PC, run the ID/head property setup utility (BRUSBSN.EXE). The following window will appear. (2) On the Model menu, click BH. MFC3100C/MFC580: Click the Port down arrow to select the LPT1. MFC3200C/FAX1800C: Click the Port down arrow to select the USB port to which the MFC3200C/FAX1800C is connected.
  • Page 21 (3) In the Serial No = BRO box, type the 9-digit serial number (e.g., L2J012345) printed on the nameplate labeled to the back of the facsimile machine as an ID code. Then press the Enter key. The setup utility will transmit the entered data from your PC to the facsimile machine and then it will terminate.
  • Page 22 TIP: The updating procedure given here uses a PC. For the updating procedure in the maintenance mode without using a PC, refer to CHAPTER 5, Subsection 5.3.14. MFC3100C/MFC580 Connecting the facsimile machine to your PC (See the illustration on page 2-1.) (1) Make sure that your PC is turned off.
  • Page 23 (1) On your PC, run the ID/head property setup utility (BRUSBSN.EXE). The following window will appear. (2) On the Model menu, click BH. MFC3100C/MFC580: Click the Port down arrow to select the LPT1. MFC3200C/FAX1800C: Click the Port down arrow to select the USB port to which the MFC3200C/FAX1800C is connected.
  • Page 24 12-digit code is printed. NOTE: The MFC3100C may fail to print it out correctly if the four starting numerals of the entered property code are other than 6666, 7777, and 8888. To print it correctly, update the current program stored in the EEPROM.

  • Page 29: Scanner Mechanism

    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.) If you set documents on the document stacker with their faces down and start the scanning operation, then the scanner motor rotates so that the ADF (which consists of the separation roller and ADF parts) feeds those documents into the machine, starting from the bottom sheet (first page)

  • Page 30: Ink Jet Printing Mechanism

    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).

  • Page 32: Ink Jet Printing And Capping Mechanisms

    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.

  • Page 33: Ink Cartridges

    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.
  • Page 34 (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.

  • Page 35: Purging Mechanism

    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.
  • Page 36 During printing: The ASF-purge switching gear 23 is During purging: The ASF-purge not engaged with purge bevel gear A (but engaged with switching gear 23 is engaged with gear 25 in the ASF gear train). 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).
  • Page 37 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).

  • Page 38: Carriage Drive Mechanism

    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.
