METHODS AND APPARATUS FOR DROPLET DEPOSITION

Abstract: a method for depositing fluid droplets onto a medium. for an actuation cycle, the steps include: assigning all fluid chambers in an array as either firing or non-firing chambers to produce bands of one or more contiguous firing chambers separated by bands of one or more contiguous non-firing chambers. for each non-firing chamber adjacent to a band of firing chambers, actuating one wall in the first direction and retaining the other wall in the neutral position. for a single non-firing chamber between bands of firing chambers, actuating both walls concurrently in the first direction. for a non-firing chamber not adjacent to a band of firing chambers, retaining both walls in the neutral position or concurrently actuating both wall in either the first or second direction. and for each firing chamber, actuating the first and second walls consecutively in the first direction.
