Printhead

The Printhead is the heart of the printer, spanning nearly the length of the

drum. Using its 1236 jet nozzles (309 jets for each primary color), with a

horizontal motion of slightly less than 5 mm (0.2 inches), the Printhead can

print the entire image on the rotating drum. The Printhead provides one size

ink drop, which is used for all print-quality modes.
