1. PRODUCT OUTLINE

1.1 Product Outline

This full color bubble jet desktop printer not only realizes high image printing through the implementation
of the PhotoRealism concept, but also higher speed printing compared to previous models.
This printer achieves high image printing by adopting "drop modulation technology" in the color BJ
cartridge and the photo BJ cartridge.
The expanded printing environment has allowed the printer to have banner printing capabilities. The
printer can also be used as a compact color scanner when the scanner cartridge is installed in the carriage.
All the function settings are easily set by the personal computer. The operation is easily performed with the
bidirectional Centronics interface (effective only for the device ID response)
This printer uses a built-in AC adapter. This is a small and light weight personal color printer with high
performance capabilities.

1.6 Banner Print

When printing on banner paper, lower the paper support and set the paper delivery flap to the upright
position. To avoid misfeeding, put a light crease between the first and second page and set the first page in
the sheet feeder. Place the rest of the banner paper behind the printer. Do not use the manual feeding slot
to avoid skewing.
Each top margin for banner printing is set at 0mm. However, to avoid printing on the platen, printing will
start 3mm from the initial top margin. Set an extra sheet at the end in case the bottom edge is not printed
on the last page.
Banner printing uses a large amount of ink. To avoid ink shortage, use of a new ink cartridge before
banner printing is recommended.

Part 4: Technical Reference

4.2.2 Logic section components

1) MPU (IC2)

The MPU contains a 16-bit CPU, 1K-bit RAM, 24-bit address bus port, 16-bit data bus port, stepping
motor controller, interrupter controller, A-D converter, I/O ports, and other components.

Built-in CPU

The 16-bit CPU operates in synchronization with a 20 MHz external clock input.

Address bus

The 24-bit address bus port is connected to an 8 M-bit control/CG ROM and printer controller. The
controller/CG ROM synchronizes with the read signals output by the MPU and the 20 MHz clock
signal. The printer controller then selects the chip.

Data bus

Like the address bus, the 16-bit data bus port is connected to the 8 M-bit control/CG ROM and printer
controller.

Stepping motor controller

The stepping motor controller outputs double 1-2 phase exciter drive signals to both the carriage motor
driver and paper feed motor driver.
The stepping motor controller can switch the the 4-step peak current value of both motor driver.

Interrupt controller

For external interruption, the MPU has ports P80, 81, 84, 85, and 87 to receive the POWER button
on/off switching, data reception, initial interrupt request, receive buffer-full warning, and other signals.
The MPU executes interrupt processing for the respective signals.

A-D converter

The following analog signals are detected after they pass through the built-in A-D converter:
AN0: The printer's internal temperature is detected by the thermistor on the logic board.
AN1: The head temperature is detected by the head temperature sensor in the BJ cartridge.
AN3: The head rank is detected by the rank resistor in the BJ cartridge.

I/O port

The setting status determined by the head ID, paper end sensor, home position sensor, and pick-up
roller sensor are input through the input ports. The buzzer, BJ cartridge detection, head-driving voltage
control, and other signals are output from the output ports.

4-39

2) Printer controller (IC3)

The printer controller contains the interface controller, print head controller, buffer controller, DRAM
controller, EEPROM controller, I/O ports, etc. It operates in synchronization with an external 22.11
MHz external clock input.

Interface controller

The interface controller receives from the computer, 8-bit parallel data which is synchronized with the
data strobe pulse (STROBE) through the BUSY/ACKNLG handshake. It also controls other interface
signals.
The data received through the interface is stored in the DRAM's receive buffer and analyzed by the
MPU.
When the printer initialization signal INIT is input through the interface to the printer controller, the
printer controller outputs a BUSY signal. Also, after INT1 is output to the MPU and print data in the
print buffer is printed, the printer is initialized.

DRAM controller

The DRAM controller is a DRAM-specific bus separated from the MPU bus. It controls the 4 M bit
DRAM's 10-bit address/16-bit data bus and also executes read/write control, RAS/CAS control, and
refresh control.

Buffer controller

The buffer controller automatically writes the received data to the receive buffer on the DRAM,
manages the receive buffer's remaining capacity, automatically reads the print buffer, and clears the data
after it is read.

Print head controller

The print head controller converts the print data read from the DRAM's print buffer from parallel to
serial and sends it to the print head. At the same time, the printed dots are counted for the variable
control of the Heat-enable (H ENB) signal pulse width.
The head-driving signals consist of the block enable signals (B ENB 1, 2, 3), odd/even enable signals
(OddENB/EvenENB), and heat enable signals (H ENB 0, 1, 2, 3). The block enable signals and
odd/even enable signals specify the block for time-shared drive. The heat enable signals control the
eject heater's conduction time.

I/O port

The I/O ports sense the

RESUME

and

CARTRIDGE

buttons' input status. The output ports control

the lighting of the

POWER

and

ERROR

indicators.

BJC-4400

3) Control/CG ROM (IC4)

The 8 M-bit control/CG ROM contains the program and bitmap font data for printer control.

4) DRAM (IC7)

Controlled by the printer controller, the 4 M-bit DRAM is used as a receive buffer, download buffer,
print buffer, and working area.

5) Reset IC (IC1)

This IC detects the power voltage when turning on the power or instantaneous power failure.

6) EEPROM (IC6)

Controlled by the printer controller, the 1 K-bit EEPROM (Electrically Erasable and Programmable
ROM) stores various function settings, the total count of printed sheets, and the total waste ink amount.

7) Carriage motor driver (IC12) / Paper feed motor driver (IC13)

The carriage motor driver which is controlled by the MPU drives both the carriage motor and the paper
feed motor which in turn are controlled by an double 1-2 phase exciter with a fixed current bipolar
drive. Upon receiving the switching signal from the MPU, the peak current value can be set
individually into 4 steps for phase A and B. By doing so, it ensures smooth operation of the motors.
