Venturi spittoon system to control inkjet aerosol |
摘要 |
An inkjet printing mechanism has an inkjet printhead which controllably ejects multiple ink droplets and a carriage to carry the printhead. The carriage is designed to move the printhead through a print zone to a service station where the printhead is serviced. During a servicing mode of operation, the printhead ejects ink droplets at the service station to clear the printhead nozzle orifices prior to printing. A reservoir is provided at the service station to collect the ink droplets ejected from the printhead during the servicing mode. A venturi passageway is also positioned at the service station adjacent to the reservoir. The venturi passageway guides the ink droplets ejected from the printhead into the reservoir.
