  • Publication number: 20260152012
    Abstract: Exemplary aspects include heating the media and drying the ink by forced convection generated from a Coanda heater. By providing and heated air flow over a curved surface, a low pressure Bernoulli effect will acquired the media to glide over the heated forced air. Similarly, by providing a cold air over a curved surface, the media will be acquired by the same low pressure principle. The cold air will cool down the media by forced convection. Direct forced air is an efficient way to heat or cool the media. An upper flow on top of the media will facilitate the removal of the evaporated ink water and solvent. The solvent could be captured by a filter. Air heaters are significantly cheaper than infrared lamps and more robust.

  • Publication number: 20260034806
    Abstract: An inkjet printer includes one or more devices to increase evaporation rates within one or more dryers in the inkjet printer. An electrostatic charge generator can be positioned before a dryer to charge media and liquid materials ejected onto the media before the media enters the dryer to increase evaporation rates. An electric field generator within the dryer can be operated to generate an electric field that is directed toward the media to increase the movement of the vapor cloud away from the media being carried by a media transport within the dryer. Additionally, a corona generator can be coupled to an AC high frequency current to generate a corona wind to increase evaporation rates within the dryer.
