3.2.2 Color/Photo BJ cartridge structure
The color/photo BJ cartridge has a printing head equipped with 64 nozzles through
which the three ink colors are ejected (16 nozzles each for yellow, magenta, and cyan).
The printing head and ink cartridge are built-in.
1) Side cover
This plastic cover is fixed to the cartridge body to prevent ink leaking from the ink
sponge.
2) Ink sponges
Each color ink (yellow, magenta, cyan) is soaked in its respective sponge. The
yellow, magenta, and cyan ink sponges are compressed and stored in the cartridge
body.
3) Cartridge body
This is a plastic case which links the ink sponge with the bubble jet head unit via
the ink filter.
4) Air Hole with Pressure Regulation Caps
As the ink is consumed, the pressure inside the cartridge decreases compared to the
atmospheric pressure. This makes it more difficult for the ink to be supplied to the
head. To prevent this, the ink cartridge has an air intake for maintaining a constant
pressure inside the cartridge body.
5) Bubble jet head unit
As dictated by the printing signals received through the signal contact, ink is ejected
through the 48 bubble jet nozzles.
6) Head cover
The plastic head cover protects the bubble jet head unit.
