Part 3: Operating Instructions
3) Replacing the BJ cartridge
Open the front cover of the printer. The carriage moves to the replacement position
(printer center). Flip up the cartridge lock lever and remove the BJ cartridge. Install
another cartridge using the procedure in the previous section 2). Store the BJ
cartridge (Color, Black, and Photo) removed from the printer in the supplied BJ
cartridge container.
CAUTION
If the printer has been operating for a prolonged period, the aluminum
plate of the BJ cartridge will get very hot. If it is hot, opening the front cover
will activate the protective function. The beeper will sound five times and
the carriage will not move the cartridge replacement position. Wait a few
minutes before attempting to replace the BJ cartridge. The carriage will
not move to the replacement position even if you open the front cover
during an ongoing printing operation or error occurrence.
