Slide2: Ink is used in a number of ways throughout the inkjet printing process. In general, ink in an ink cartridge is used for printing documents, photographs and other such materials. Some ink, however, must be used to maintain the health of the print head; some ink is residual; and some ink evaporates. These uses of ink are common, in varying degrees, to printers from all inkjet printer manufacturers. Slide3: The methodologies used to measure page and photo yield do not account for all the uses of ink described above and therefore your actual yield may vary considerably from the published yield (see Inkjet page yields and Inkjet photo yields). HP designs its inkjet printer systems to deliver outstanding value in printing customer documents while using enough ink to maintain a reliable printing system that delivers outstanding print quality over the life of the printer. Slide4: In the printing process, some ink is used to prepare the printer for use HP offers two general inkjet print head designs: integrated into the ink cartridge (Integrated Print Head: IPH), and a long-life print head integrated into a printer which has Individual Ink Cartridges (IIC). Both IPH and IIC printers commonly perform start up and calibration processes, which consume some ink, to ensure reliability and optimize print quality. IIC printers also may use ink to prepare the long-life print head for use by purging storage fluid from and pumping ink through the print head. IIC printers may use more ink in start-up than IPH printers as a result of these additional start-up procedures. When a replacement cartridge is installed in either IIC or IPH printers, replacement cartridge start-up routines require some ink. Slide5: Some ink is used to service the print head and prevent clogging Print head nozzles get clogged over time, most commonly by microscopic dust particles or dried ink. Nozzles are kept clean by servicing, including wiping the surface with a small rubber wiper, ejecting ink through the nozzles to purge particles and to prevent drying, and pumping with ink to clean the print head. To keep the printer ready to print in either color or black, these service routines typically consume some ink from every cartridge, even if only black or color is used in the document being printed. Slide6: Tiny bubbles of air form in the ink over time and can block the flow of ink in long-life print head printers (IIC). In some IIC printers, air bubbles can be caused by an ink cartridge change. Air bubbles can be removed by pumping them out of the print head. When removing these air bubbles, some ink is also removed.On IIC systems, multiple colors may use the same print head. When a single color cartridge is changed, some ink is also consumed from the other color ink cartridges using the same print head.
