Continuous ink-jet printhead having serrated gutter

摘要

A continuous ink jet printhead is provided. The printhead includes a source of ink drops, a first nozzle row, and a second nozzle row displaced in a first direction and a second direction relative to the first nozzle row. A selection device is positioned relative to the first and second nozzle rows. The selection device is configured to direct ink drops ejected from the source through the first nozzle row along a first selected ink drop path and a first non-selected ink drop path. The selection device is also configured to direct ink drops ejected from the source through the second nozzle row along a second selected ink drop path and a second non-selected ink drop path. A gutter is positioned adjacent the first and second non-selected ink drop paths. The gutter is shaped to collect ink drops traveling along the first and second non-selected ink drop paths. The gutter includes a housing defining an ink removal channel. The housing has an edge with a second portion of the edge being displaced in the first direction and the second direction relative to a first portion of the edge such that displacement of the second edge portion corresponds to the displacement of the second nozzle row.
