The printhead is an integrated assembly of six trains of nozzles. Capable of controlling each nozzle individually, the printhead implements discharge control for six
colors by itself.
a) Nozzle arrangement
The nozzle assembly is formed of 1,280 nozzles arranged at 600-dpi intervals in a zigzag pattern, offering a total of 2,560 nozzles 1,200-dpi intervals.

b) Nozzle assembly structure
Inks supplied from the ink tanks are filtered through a mesh ink filter before being sent to the nozzle assembly. Each nozzle train is supplied with an ink from the
common nozzle chamber. When a head drive current flows through the nozzle heater, the ink boils, generating bubbles to discharge ink drops from the nozzle from
the nozzle assembly.
