Abstract
A matrix arrangement for inkjet pens used in inkjet printing mechanisms provides increased throughput and a narrower product than the traditional pen arrangements laying side-by-side along the scanning axis. The matrix inkjet cartridge has at least two chambers perpendicular to the scanning axis. For example, a two-by-two matrix arrangement in a four pen cartridge system requires less distance for all of the nozzles to traverse the entire print zone. Thus, throughput, often measured in pages per minute, is increased. Moreover, the overall product width may be decreased to provide a more compact product for consumers. A method is also provided of dispensing ink using an inkjet printing mechanism, as well as a method of delivering ink through an inkjet cartridge where ink is extracted from storage chambers through ports located on opposing sides of a plane parallel to the scanning axis.
