    BJC-3000 Part 5: Appendix 1.1.3 Advanced paper feed function To improve the paper feed speed, this printer has an advanced paper feed function. With this function, when multiple pages of plain paper with a page length longer than letter-sized paper, are printed in HS mode, the printer begins feeding of the next page before ejection is completed.

    Part 5: Appendix BJC-3000 1.2 About the Purge Unit The purge unit maintains the nozzles of the BJ cartridge in order to maintain printing quality. The purge unit's functions can be divided into capping, cleaning, and paper feed motor drive switching functions. 1.2.1 The capping and cleaning functions of the purge unit The purge unit’s cap is pressed against the face of the print head to prevent the ink from drying out and to avoid particles adhering to it.

    BJC-3000 Part 5: Appendix 1.2.2 Purge unit paper feed motor drive switching function The paper feed motor drive switching function performs the switching of the paper feed motor's drive power to drive the auto sheet feeder or the purge unit. 1.2.3 Purge unit structure and functions Capping Unit For Black BJ Cartridge...
  • Page 94 Part 5: Appendix BJC-3000 c) Wiper unit The wiper unit, controlled by the position of the carriage unit, performs wiping operations. When the carriage moves from left to right, the carriage moves the purge unit's wiper flag, and while raising and setting the wiper, caps the cartridge. When the carriage moves from right to left, the wiper wipes, after which the carriage moves the wiper release unit to unlock the wiper latch and the wiper is lowered.

    Part 5: Appendix BJC-3000 1.3.3 USB interface USB is a serial interface which connects up to 127 peripheral devices to a host computer, and transmits data at a high-speed rate of 12Mbps. Hot plugging, in which connecting/disconnecting devices while the host or the printer is in use, is supported. Each device is connected to a hub's port, where each port's detection/disconnection status is returned to the host.

  • Page 97: Automatic Interface Switching Function

    BJC-3000 Part 5: Appendix 1.3.4 Automatic interface switching function This printer has a function to automatically switch the interface. With this function, when printing is not executed from either interface, printing can be executed from either the USB or the parallel interface. The switching cannot be performed until after the printing starts from one of the interfaces and the buffer becomes empty after printing.

  • Page 100: About The Scanner Cartridge

    Part 5: Appendix BJC-3000 1.5 About the Scanner Cartridge The scanner cartridge is a replaceable scanner unit. It carries a one-line 256 pixel CCD, and by scanning the same line three times, switching each of the three RGB primary colors of the LED, it separates one line of the color image into three RGB colors, output in 8-bit signals (256 gradation in each RGB color).

  • Page 101: Scan Modes

    BJC-3000 Part 5: Appendix 6) Scanner Controller The scanner controller is an IC that processes the analog signals into digital images. a) Sensor Control The sensor control controls the LED and the CCD. b) Amplifier The amplifier amplifies the analog input from the CDD. c) Analog Signal Control This unit performs offset correction for the amplified analog input, black-level correction which sets the maximum value to black, etc.

    Part 5: Appendix BJC-3000 1.5.3 Image gradation and bit data size Refer to the description below for the relationships between the image gradation and the bit data size. a) 256-gradation/8-bit data/multi-value 256-gradation is processed by 8-bit data. Within the scanner, the image processing unit in the scanner controller normally processes the 8 bit data.
