Two pass print mode method and apparatus for limiting wind-related print defects
Abstract:
A two pass print mode method and apparatus limits wind-related print defects produced during printing, utilizing a reciprocating carrier of a printer carrying a printhead having an array of columns of actuator-fired fluid-jetting nozzles along a bi-directional scanning path. Due to instructions from a controller, printing proceeds along an initial partial swath on a print medium during a first pass along the scanning path by firing actuators associated with a first plurality of segments of a given column of nozzles. Then, printing proceeds along a final partial swath on the print medium during a second pass along the scanning path by firing actuators associated with a second plurality of segments of the given column of nozzles. Each segment of nozzles of the first and second pluralities includes more than one consecutive nozzle so that gaps are created in the partial swath printing accommodating wind-related effects without causing wind-related print defects.
