Support of the USB I/F function.

(4)

Photo printing function.

2. CHANGES FROM THE BJC-50/50v

1)

New adoption of the photo cartridge (Photo printing function has been added.)

4-3-1. Restrictions on IrDA communication under Windows 2000

The following restrictions or problems occur in case of communication via IrDA under

Windows 2000, connecting with this printer.

As only one-way communication is possible, status information of the main unit cannot be

obtained, causing the following restrictions:

1) The status monitor does not function.

Therefore, the status monitor is disabled by default in the printer driver of this printer

in the case of communication via IrDA under Windows 2000. Users can start the

status monitor by selecting "Start Status Monitor" from the "Property" sheet, however,

"Communication Impossible" is indicated.

2) The installed cartridge is unknown.

3) The possibility of ink-low error is displayed only by printer LED. (The information

is not displayed on the host computer.)

4) The print job cannot be canceled from the host computer when an error has occurred.

After the cause of the error is resolved, the printer can be recovered by pressing the

RESUME button on the printer's operation panel. The error can then be recovered on

the host computer, although the ongoing print job is deleted.

Plug and Play is not supported.

1) The host computer occasionally fails to recognize the infrared port of the printer in

4Mbps communication. "Hard power reset," i.e. disconnection of the printer from mains

power and removal of the battery, is required to recover from this condition. The

frequency of occurrence and the duplication are low. In case of frequent occurrence,

however, this problem can be avoided by lowering the communication speed.

2) If the cleaning operations, etc., start during printing, the error message "Write error"

may be displayed on the host computer. When the cleaning operations, etc. are

finished, the error message disappears, and printing operations continue.

3) If another operation is executed at the host computer (eg., launching another

application) while printing a large file (printing photo images from Photoshop etc.),

paper may automatically be ejected, or the printer may reset.
