  • Digital printing system with improved toner removal
    Patent number: 9164412
    Abstract: A digital printing apparatus comprising a developing roller (102) and an image carrying roller (101); the developing roller (102) being arranged to transfer liquid toner (107) onto the image carrying roller (101) in accordance with a charge pattern; an upstream charger (111) upstream of an area (108) of rotational contact between the developing roller (102) and the image carrying roller (101); a downstream discharger (112, 122, 132) downstream of the area (108); a sensor (200) downstream of the area (108) to detect a property representative of the charge of a liquid toner residue; and a controller (210) to receive sensor data from the sensor (200) and to provide a control signal to control the downstream discharger.
