Abstract
Disclosed are devices and methods where a distance between nozzle arrays is equal to a substrate advance distance corresponding to at least one complete turn of a rotating drive body.
Claims15
A fluid ejection device, comprising
- a first nozzle array,
- a second nozzle array arranged downstream of the first nozzle array, and
- at least one rotating body for advancing a substrate with respect to the nozzle arrays, wherein
- a pitch of the first and second nozzle array equals a substrate advance distance corresponding to at least one complete turn of the rotating body.
A method of compensating for a registration error in a fluid ejection device by setting a pitch of a first nozzle array and a second nozzle array, arranged downstream of the first nozzle array, equal to a length that a substrate travels over at least one complete period of a periodic error function.
A method of ejecting fluid, comprising
- a first nozzle ejecting a first dot onto a substrate,
- a rotating body making at least one 360 degrees turn, a substrate advancing over a corresponding first distance, and
- a second nozzle said first distance apart from the first nozzle ejecting a second dot onto the substrate.
