A device for an inkjet printer includes a compliant cap, which in turn includes a floor and flexible walls extending upwardly from the floor, and a lip formed on the walls. The floor, walls and lip define an open interior volume sized to accommodate a print head assembly of the inkjet printer. The device further includes a cap post that accommodates the compliant cap and supports the floor.

Capping for inkjet printers

A fluid containment system includes an ink depository and a hood secured thereto. The hood includes an ink redirection structure for directing ink emitted from a printhead through a constrictive conduit into the ink depository.

Fluid containment system including an ink redirection surface

An inkjet printhead servicing station for an inkjet printing mechanism includes a translational pallet that carries servicing appliances, like wipers, caps and flaps. A service station frame defines a guide track that supports the pallet for translational movement in a plane substantially parallel with a printhead plane and in a direction substantially perpendicular to the scanning axis of the printhead when transported by a carriage. The frame has adjacent pallet and carriage alignment datums. The pallet has a carriage lock that secures the carriage with or without the inkjet printhead installed therein. The pallet has a rack gear that is driven with a spindle pinion gear. The service station frame has a base and a bonnet cover that define the guide track, with the pallet being sandwiched therebetween. An inkjet printing mechanism having such a service station, and a method of assembling a service station are also provided.

Integrated translating service station for inkjet printheads

An inkjet printhead service station for an inkjet printing mechanism includes a platform that is translationally moveable perpendicular to a scanning axis along which a carriage transports the printhead. The sliding pallet carries servicing appliances, like wipers and caps for servicing the printhead orifice plates, as well as flaps for cleaning cheek regions of the printhead adjacent the orifice plate. The pallet may be moved to expose a spittoon formed thereunder for spitting ink from the printhead. An upper bonnet portion of the service station frame has a scraper bar for removing ink residue from the wipers and flaps. An inkjet printing mechanism having such a service station, and a method of servicing an inkjet printhead are also provided.

Translational service station system for inkjet printheads

A vertical axis service station adjustment device or tool for adjusting a position of an inkjet printhead service station with respect to a plane defined by a chassis of an inkjet printing device that includes at least one inkjet printhead is disclosed. An embodiment of the adjustment device includes a base, a pair of ramps, and an adjustment mechanism. The base is slideably mounted on the chassis so as to be capable of translation along the plane defined by the chassis. The ramps are coupled to the base and each define an angled track that supports the service station and with respect to which a member of the service station rides during translation of the base. The adjustment mechanism is coupled to the base and is actuable to translate the base along the plane, thereby moving the angled track of each ramp with respect to the member of the service station on that track, which results in movement of the service station in a direction that is at an angle to the plane defined by the chassis. An inkjet printing device including the above-described tool is also disclosed. A method of adjusting a position of an inkjet printhead service station with respect to a plane defined by a chassis of an inkjet printing device is further disclosed.
