Abstract: A wet-wiping printhead cleaning system for inkjet printer incorporating a wiper for wiping the printhead including a treatment fluid applicator configured for placing treatment fluid onto at least one element of the printhead and wiper elements involved in wiping the printhead orifice plate surface, the treatment fluid being placed on said at least one element by direct contact of the applicator, subsequently the wiper wipes the printhead, the treatment being available to enhance cleaning effectiveness, the treatment fluid lubricating the wiper so as to lengthen wiper service life and enhance wiping performance, as well as acting to render unwanted accumulations on the printhead more removable by wiping.

Abstract: An inkjet printer has a printhead mounted in a carriage which periodically moves in a carriage scan direction to a stop position in a service station where an actuation device causes a wiper blade to move back and forth across ink orifices on a nozzle surface of the printhead during a wiping operation. The actuation device incorporates a rotating lead screw to impart transtlational motion to the wiper blade in a wiping direction orthogonal to the carriage scan direction. A clutching action prevents further movement of the wiper blade after completion of each wiping step. The actuation device is driven through a gear train from a motor such as a media advance motor. An ink spittoon is incorporated in the same service station for receiving ink generated during a spitting operation, and a scraper in the ink spittoon removes residual ink from the wiper blade.

Abstract: A method for operating an ink jet printer that includes the steps of performing a printer turn-on printhead service on a printhead cartridge of the printer; resetting a page counter, an uncapped condition time counter, and an ink drop counter, wherein the page counter counts the number of pages printed, the uncapped condition time counter counts the amount of time that the printhead cartridge is in the uncapped condition, and the ink drop counter counts the number of ink drops emitted by the printhead cartridge; printing a plurality of pages of print media; after a page is printed performing a post-prime printhead service if the printhead cartridge was primed during the printing of the page; and after a page is printed performing a print time printhead service if the printhead cartridge was not primed during the printing of the page and if (a) the ink jet printer has printed at least a predetermined number of pages since the page count counter was reset, (b) the printhead cartridge has been uncapped for at le
