Abstract

Four-color, drop-on-demand thermal ink jet printing places a stringent requirement on relative alignment of the four separate printheads. As pixel resolution increases, this precision must increase. It is difficult to precisely align the printheads. Strategies of using separate, disposable printheads also demand a precision aligning fixture that an untrained user can use to precisely reposition replacement cartridges.
