Abstract: An inkjet waste ink handling system embodiment of the present invention includes a spittoon reservoir for collecting waste ink dropped from an inkjet printhead, and a ramp within the spittoon reservoir having an upper end that receives any ink dropped in and a lower end to which gravity conveys such ink. In this way, pillars of dried ink are prevented from accumulating.

Abstract: An indexing service station services interchangeable first and second inkjet cartridges when installed with a third inkjet cartridge in a dual-cartridge carriage of an inkjet printing mechanism. For printing graphics and text, the first cartridge usually prints black ink, while the third cartridge prints full-colorant concentrations of colored ink. For printing photographic type images, the black cartridge for printing text is replaced with the second cartridge which is an imaging cartridge. The imaging cartridge carries ink formulations having reduced colorant concentrations, which, when used in conjunction with the full color cartridge, provide near photographic image quality, as well as crisp black text and line art. The service station has three separate sets of servicing tools for independent servicing of the black, full color, and imaging cartridges.
