A method for media jam clearing includes detecting a media jam with sensor in the printer, in which the media jam comprises a sheet of media stuck in a media path of the printer. The method further includes monitoring for user action that alters the mechanically alters the state of the printer and detecting a user action that mechanically alters the state of the printer. In response to detection of the user action, the printer automatically attempts to clear the media jam.

Various embodiments of a duplexer are disclosed in which a guide directs a sheet to a first transport which continues to move the sheet in a first direction or moves the sheet in an opposite direction to subsequently overturn the sheet.

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.
