Figure 3-7 Installing the BJ Cartridge
If the BJ cartridge is not installed correctly, the beeper sounds once when
the CARTRIDGE button is pressed, and the carriage cannot be returned to
the capping position. If the carriage does not move to the capping
position, remove and reinstall the BJ cartridge. If the error still persists,
see Part 5: 5. TROUBLESHOOTING (page 5-5) .
Since the carriage is secured by the lock arm in the capping position,
never pull the carriage ribbon cable to move the carriage to the center.
If the beeper sounds and the carriage does not move at all when the
CARTRIDGE button is pressed, the BJ cartridge may have overheated.
Leave the printer to cool down and wait a while before pressing the
CARTRIDGE button again.
