Replacing the BJ Cartridge

Insert the ink tank(s) in the new BJ Cartridge.
You can use new ink tanks or the ink tanks in the worn BJ Cartridge, and
install them in the new BJ Cartridge.
Replacing the Ink Tanks
Install an ink tank immediately after removing it from the worn BJ Cartridge
or its package. If an ink tank remains exposed for a long period, it may run
out of ink quickly after it is installed.

The cartridge holder returns to the home position and print head cleaning
