Front end components and their main roles
- Piezoelectric plate
Applying a voltage stretches the plate, serving as the actuator for spraying ink. Consisting of
thin piezoelectric plates laminated together, this plate can be driven even by a low voltage.
- Filter
This removes foreign materials from the ink.
- Metal plates
These form the head nozzle pressure chambers, ink flow paths, and manifolds.
- Nozzle plate
This plate has a total of 376 nozzles--47 nozzles x 2 lines staggered x 4 rows (black, yellow,
cyan, and magenta).
- Head driver
This flexible circuit board holds the piezoelectric driver chip.
