Operation Manual

Air paths/Tank 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 pipes
The ink pipes transport the ink between the ink tank and ink guides.
Ink filters
The inks are filtered to prevent foreign objects from getting into the ink paths.
Tank packing
The tank packing ensures that the ink tank and ink pipes are in close contact to
prevent ink leakage.
BJ head unit
The BJ head unit receives the ink from the ink guides and ejects the ink at the print
media according to the print signals from the signal contacts.
Head clip/Screws
The BJ head unit is fastened to the cartridge body using head clip and screws.
Ink guides
These form the ink path between the ink pipes and BJ head unit.
Head packing
The head packing ensures that the ink guides and BJ head unit are in close contact
to prevent ink leaking.
