3.2.1 BJ cartridge structure

1) BC-60
In the BC-60, the BJ head is unified with the ink tank.
Cartridge body
The cartridge body houses the ink sponges and is the base for the BJ head unit.
Ink sponges
The two ink sponges hold the ink and ink optimizer that are fed to the BJ head unit.
Ink pipes
The ink pipes transport the ink from the ink sponges to the BJ head unit.
Cartridge cover
The cartridge cover is welded to the cartridge body to prevent inks leaking from the
body.
Air paths/Cartridge label
Air vents or paths are created between the inside and outside of the BJ cartridge
through the holes and grooves in the cover and the label that is applied to it.
The air vents prevent pressure fluctuations inside the BJ cartridge due to ink
consumption and atmospheric conditions, and help stabilize the supply of inks to
the print head.
Ink filters
The inks are filtered to prevent foreign objects getting into the ink paths.
