Abstract
An inkjet printing system having a replaceable set of ink-related components which are installed together and replaced together as a single ink delivery system for each different color of ink. The set includes an ink printhead cartridge with an inlet port, an ink supply module, and a printhead service module, each of which is manually mountable by a user onto an inkjet printer. The ink supply module contains enough ink to completely replenish an entire printhead reservoir several times before the expected useful life of the printhead cartridge has expired, at which time a user can replace the entire set of ink-related components for a particular color. Similarly, the printhead service module is designed for reliable performance for the expected useful life of the printhead cartridge. This system enables the entire ink delivery system to be replaced for different printing needs, such as replacing indoor dye-based inks with outdoor pigment based inks.
