This invention describes a removable cartridge for an inkjet printer. The cartridge has an internal structure that divides it into several sections, with individual ink containers fitting into each section. A printhead is attached to this cartridge, drawing ink from these containers. The claims specifically detail the printhead as being made from two pieces glued together, one forming ink channels and the other feeding ink into those channels from the containers.
Why it matters: Manufacturing techniques for microfluidic printheads, including precision etching and and bonding, have advanced significantly since 2008, potentially making the specific printhead construction described in the claims more cost-effective to produce.
