Abstract: A bellows capping system is provided for sealing ink-ejecting nozzles of an inkjet printhead in an inkjet printing mechanism, such as a printer, during periods of printing inactivity. The system includes a support which moves between a sealing position and a rest position. The system also has a cap which extends from the support and terminates in a lip. The lip surrounds the nozzles when the support is in the sealing position. The cap has a wall with first and second leg portions joined together at a knee portion between the support and the lip. When sealing the printhead, the knee bends or buckles so the first and second portions collapse toward each other. Multiple knee portions may join together multiple wall portions in a bellows or accordion arrangement. An inkjet printing mechanism having the bellows capping system and method of using this capping system are also provided.

Abstract: A ganged inkjet printhead sealing system maintains inkjet printhead health in an inkjet printing mechanism during periods of printing inactivity. In multi-printhead printing mechanisms, separate caps seal against each of the printheads. The caps each have an outlet vent. The vents are all ganged together and fluidically coupled to a single, common pressure regulation chamber that isolates the environment adjacent the printhead nozzles from the external environment when the printheads are capped. A fluid in a U-shaped manometer tube, or an elastomeric bladder are used to isolate the pressure chamber environment. The bladder may be constructed as a thin-walled sheet, a spring-biased bag, or as a bellows. The pressure chamber volume changes to accommodate pressure spikes during the capping process, as well as environmental changes in temperature, elevation, barometric pressure, etc. An inkjet printing mechanism having such a ganged capping system, along with associated capping methods are also provided.
