RECORDING SECTION
• BJ cartridge loading mechanism
The BJ cartridge is fixed mechanically onto the cartridge holder. At the
same time that it is fixed onto this holder, the BJ cartridge pressure con-
tacts the signal contact pad of the carriage ribbon cable to form an electri-
cal connection. By this connection, signals such as print signals are sent to
the BJ print head. The printer control section monitors the mounted state
of the BJ cartridge at all times, and judges that there is no cartridge if the
BJ cartridge head is not electrically connected with the signal contact pad
of the carriage ribbon cable for a certain period or more.
