发明名称 Liquid capping system for sealing inkjet printheads
摘要 A liquid capping system for sealing the ink-ejecting nozzles of an inkjet printhead during periods of printing inactivity uses a vicious, inkjet ink compatible, sealing liquid that is applied to the printhead surface to seal the nozzles and prevent the ink in the printhead from drying. An inkjet printing mechanism houses the printhead and has a service station that stores the sealing liquid. To selectively apply the sealing liquid to the printhead, the service station has an applicator mechanism including a dispenser member and a sealing wiper that transfers the sealing liquid from the dispenser member to the printhead. The sealing wiper may also clean the printhead face or be dedicated to only sealing the printhead. A method is provided for sealing an inkjet printhead using a liquid capping system, including the step of spitting the printhead to clear the sealing liquid from the nozzles before returning to printing.
