Abstract
A method is provided to reduce vertical banding defects in an ink jet printer. The method includes the steps of identifying a disturbance frequency of a disturbance source; identifying a natural frequency of a printhead carrier system; correlating the disturbance frequency of the disturbance source and the natural frequency of the printhead carrier system to a base carrier velocity; selecting a first carrier velocity for printing in a first direction, the first carrier velocity being different from the base carrier velocity; and selecting a second carrier velocity for printing in a second direction, the second carrier velocity being different from the base carrier velocity and different from the first carrier velocity.
