1. PRODUCT OUTLINE

The BJ M70 and the BJC-85 are portable, color BJ printers targeting the personal use

market. As successive models of the BJC-80/80v, the following functions have been

added, the ease of connection has been improved, and the functions as a portable space-

saving printer has been strengthened.

(1) The high-speed IrDA (Ver.1.1) enables the printer to attain print speed comparable

to that of the Centronics interface.

(2) Direct printing from digital cameras by the new standards of IrTran-P.

(3) Support of the USB I/F function.

(4) Photo printing function is added.

2. CHANGES FROM THE BJC-80/80v

1) New adoption of the photo cartridge (Photo printing function is added.)

2) The IrDA version upgrade from Ver. 1.0 to 1.1 has enabled faster transmission.

3) New adoption of IrTranP (Direct printing from digital cameras, enabled only in BJ M70).

4) New adoption of USB I/F

5) One emulation (BJC-85: LQ mode / BJ M70: BJ mode)

6) Button reset of the ink low warning is added.

7) Various specifications / Circuit diagram

8) Special tool (spur cleaner) is added.

3. EXTERNAL APPEARANCE

The BJ M70 and the BJC-85 have the same appearance as the BJC-80/80v, except for the

following:

(1) The USB I/F connector has been added to the right side of the printer.

(2) The color of the panel cover and inner cover has been changed from gray to blue.

Series B

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.

Data transfer

The data transfer in USB is executed in terms of the transfer unit called a frame, a time

frame of approximately 1ms, into which the data is divided. Data is transferred by piling up

these frames.

All packets begin with a SYNC (synchronizing) field to synchronize with the local clock,

and are separated with an EOP (End of Packet) field.

Frame lines begin with an SOF (Start of Frame) packet. An SOF is composed of a PID

(Packet Identification Field) that represents the type of the packet and the direction, frame

number, and a CRC (Cyclic Redundancy Check) used for error-check.

Inside a frame is a packet line containing a token packet, data packet and a handshake

packet, which indicates the status of the flow control.

A token packet is composed of a PID, an address field which can specify up to 128

addresses, an ENDP (endpoint) field, and a CRC.

Inside a data packet are a PID, data field, CRC, and EOP.

Only a PID is present inside the handshake packet.

Encoding/Decoding the Data

In USB, data transfer lines are ultimately encoded with NRZI (Non Return to Zero Invert)

method. When the original data bit is 0, sent data bits are inverted; when the original data

bit is 1, the value is retained.

However, if the level of the transferred data remain unchanged for a certain period of time,

the receiving side may not be able to synchronize with the data sample position, which will

result in data bits being out of phase. This is prevented by a method called bit stuffing;

when data bit 1 is repeated 6 times, one 0 bit is added to the original data before encoding

with NRZI.

Photo print mode can be used to obtain high level gradation print quality when using the

Photo BJ cartridge. These cartridges contain light density ink which achieves a rich

gradation and reduced graininess by printing several times over the same dot.

The printer driver divides the pixel data into a maximum of 4-values (not printed, print 1

dot, print 2 dots and print 3 dots) enabling each pixel to be printed in up to 4 gradations.

The printer therefore makes three passes using a maximum of 150% more ink than usual.

This Photo cartridge adopts drop modulation, decreasing granularity of the light density

parts by efficiently ejecting large and small ink droplets.

The printer has no detection function of the ink cartridge type, and for the BC-11e and BC-

12e, the ink cartridges to be installed are not incompatible, therefore, the following mistaken

installation may occur. In case the BCI-12 Bk/Color are installed in the print head of the BC-

11e, as the printer recognizes that the color cartridge (BC-11e) has been installed in spite of

light density photo ink cartridge installation, low density imaging is produced. In case of the

installation of the BCI-11 Bk/Color in the print head of the BC-12e, in reverse, high density

colored imaging is produced.
