Abstract
A color inkjet printer includes an electrode that emits an electric field into a gap between a printhead and a media transport that carries media past the printhead. Image data generated by an optical sensor after an ink image is printed on the media is analyzed to measure at least one image quality metric. When the measured image quality metric is outside of a tolerance range, the voltage of a voltage source electrically connected to the electrode is adjusted to improve the wetting of the media type with the ink ejected by the printhead.
Claims17
A color inkjet printer comprising:
- at least one printhead having a nozzle plate with a plurality of nozzles in the nozzle plate, the plurality of nozzles being configured to eject liquid ink drops;
- a media transport having a belt configured to carry media past the at least one printhead in a process direction to receive the liquid ink drops ejected by the at least one printhead;
- a platen made of a high dielectric constant material, the platen being positioned opposite the media transport;
- at least one electrical voltage source;
- and
- a plurality of electrodes embedded in the platen, the electrodes being configured to emit an electric field into a gap between the at least one printhead and the media transport without the electric field reaching the nozzle plate, the electric field being emitted from the plurality of electrodes in response to the at least one electrical voltage source being operatively connected to the electrodes.
