Abstract
The novel pen body construction described herein includes multiple ink storage compartments communicating with a multi-orifice printhead, and these compartments are adapted to receive sections of ink-storage foam. Preferably, this foam is a reticulated polyurethane foam of controlled porosity and capalarity and is especially well suited for storing different ink colors, such as cyan, magenta and yellow. However, single compartment black ink storage is also within the scope of this invention.
