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 spacesaving 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.

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.
