Abstract
A collection spittoon with a vacuum connection draws air and ink ejected during service spitting through an opening in the top of the spittoon. The collected ink includes main ejected drops and aerosol generated during the service process. A method for servicing an inkjet printhead comprises positioning the printhead over an opening in a spittoon chamber, establishing an air flow into the chamber through the opening, actuating the printhead to spit ink droplets in a service mode, and collecting the ink droplets and associated aerosol by drawing the ink droplets and aerosol into the chamber with the air flow.
