Chapter 1 Product Information Technology Update Modular Ink Delivery System A modular ink delivery system is the separation of ink cartridges and printheads into individual, single-color components. Traditional inkjet printers use one black and one tri- color ink cartridge, each with integrated printheads. HP’s modular ink delivery system features four separate ink cartridges--one for each primary printing color--and four corresponding long-life printheads, with tubes connecting the components.

Technology Update How It Works By separating the ink cartridge from the printheads, a modular ink delivery system allows the ink supply to remain in a permanent, fixed position. The printheads remain attached to the carriage and move back and forth, delivering ink to the page as the paper advances through the printer. Each printhead and ink cartridge is embedded with a tiny memory device called a smart chip that recognizes and stores the unique operating characteristics of the component to creat

Technology Update The Benefits Cuts up to 30 percent off the printing costs of other methods Modular design means only the component that is no longer useful is replaced. Longer-life printheads and higher-capacity ink cartridges means less frequent replacement. Achieves color laser speed in a personal desktop printer Each Printhead has 304 nozzles (1,216 total, the most in the industry) resulting in faster print speeds. Prints in 1/2-inch swath as opposed to the 1/5- or 1/3-inch swaths o
