Printhead health systems: Service Station, Primer system, and Left Spittoon
Functionality
The service station is responsible for printhead maintenance. It takes action to clean ink residues and service
ink nozzles, and prevents ink from drying in critical zones by capping the printhead once printing has nished.
The Primer system provides the necessary air pressure to the printhead to perform initialization. This system
also provides pressure to the necessary printhead service operations (by boosting air which pushes ink out
through the printhead nozzles, cleaning residues of dried ink and other particles).
The Left spittoon is a small container located to the left of the print-zone area, this is the area used by the
printhead to “spit” a small amount of ink at the end/beginning of the printing swath in order to ensure correct
nozzle heath for left-to-right printing.
