<Technical explanation>
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 BC12e, the ink cartridges to be installed are not incompatible, therefore, the f ollo wing mistak en
installation may occur. In case the BCI-12 Bk/Color are installed in the print head of the BC11e, 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.

5-3. INK LOW WARNING RESET BY BUTTON OPERATION
Ink low warning
This printer detects the remaining ink level by counting the number of ejected ink dots in
the same way as the BJC-80/80v. When the setting of the ink low warning is enabled, and
the remaining ink gets low, the beeper sounds twice, and the ERROR LED blinks.
Pressing the cartridge replacement button will sound the beeper and move the carriage to
the center, and the ERROR LED indicates the ink cartridge for which the remaining ink is
low as shown below.
The ink low warning reset function by button operation is added to this printer. The button
operation procedures are shown below. (The ink low warning of the BJC-80/80v can be
reset from the host computer only.)
Operation
1) Turn on the printer.
2) Press the cartridge replacement button to move the carriage to the center.
If the carriage was moved to the center by signals from the PC, the reset operation
by the cartridge replacement button is not possible.
3) Make sure that the proper cartridge is installed in the carriage. If not, install the proper
one. (The ink dot counter reset is effective only to the ink cartridge type installed in
the carriage.)
4) Press and hold the
RESUME
button for the number of beeps corresponding to the
warned ink type to select the ink type for which the dot counter is to be reset, and
release the
RESUME
button. The number of beeper sounds is as follows:
Once: The dot counter of the BCI-10/BCI-11Bk/BCI-12Bk is reset.
Twice: The dot counter of the BCI-11Color/BCI-12 Color is reset.
3 times: The dot counter of the BCI-11Bk&Color/BCI-12Bk&Color is reset.
4 times: The selected ink type is canceled.
5) Press the cartridge replacement button.
The ink dot counter selected in the procedure 4) and the ink low warning are reset, and
at the same time, the carriage returns to the home position.

5-4. DIRECT PRINTING FUNCTION OF THE IMAGE FROM DIGITAL CAMERAS
(BJ M70 only)
<Difference from the BJC-80/80v>
The new adoption of IrTranP has enabled the printing of data directly sent from
digital cameras compliant to IrTranP standards, not through the host computer, but
via IrDA communication.
Specifications
Data communication form: IrTranP standards compatible
Input image size: 640 x 460 pixels
Input image capacity: 128 Kbyte or less
Output image size: Landscape: 90 x 68 mm
Portrait: 77 x 103 mm
Seal printing: 19 x 26 mm x 16 images
Paper size: Postcard
Operation
<Image printing>
After receiving the data, the image data is output by pressing the
RESUME
button, and
releasing before the beeper sounds. This is not effective when an error has occurred or
paper is fed.
<Reprinting>
The image data is also maintained in the memory after printing, and will not be abandoned
until new image data is received from the digital camera, or print data is input from the
host computer. Reprinting of data is possible by pressing the
RESUME
button (and
releasing before the beeper sounds).
<Printing cancellation>
During the printing of image data, printing is cancelled by pressing the
RESUME
button
until the beeper sounds once, then releasing. In this case paper is delivered. The
remaining data halfway through printing is abandoned. (As the image data has been
maintained, it is possible to reprint the data, without resending the data from the digital
camera.)
<Printing position definition>
To select the printing position, press the POWER button and cartridge replacement button
simultaneously when the power is on, and release the buttons after the beeper sounds the
number of times applicable to the printing position to be selected. This setting returns to
the default (Landscape) by powering off. The number of beeper sounds is as follows:
Once: Portrait
Twice: 16-image seal printing
3 times: Photo glossy card landscape
4 times: Photo glossy card portrait
5 times: Setting completed. (The power is normally turned on.)

6. SPECIAL TOOLS
Clean spurs by using the spur cleaner in case spur marks are left on the print images.
Special tool (part number) Remarks
Spur cleaner (QY9-0055-000) For cleaning spurs
Usage
1) Moisten the fabric part of the spur cleaner with approx. 5 cc of water.
Moisten the fabric with the water, as shown below, so that the fabric absorbs the water
from end to end.
Be careful not to moisten the fabric with too much water. In case too much water is
used, there is the possibility that water will be wrung from the spur cleaner when
passing through the paper feed roller, spread inside the printer, and cause failure.
2) Turn on the power of the printer. Remove the paper from the ASF to set the spur
cleaner with the fabric-affixed part of the cleaner face-up and to the top.
3) Press the
RESUME
button, and release it after the beeper sounds once. The spur
cleaner is fed and stops at the print start position.
4) Press the
RESUME
button again, and release it after the beeper sounds once. The spur
cleaner is delivered. Repeat procedures 3) to 4) approx. 5 times in case of heavy soiling.
5) Set a single sheet of paper to the ASF to repeat procedures 3) and 4). (To remove the
moisture remaining in the paper feeding path.)

is absorbed by the
