  • Imaging system and defect detection program based on toner image check pattern data
    Patent number: 11454914
    Abstract: An imaging system includes a toner imaging device to form a toner image, a toner image conveying device to convey the toner image, a medium conveying device to convey a medium, and a toner image recording device to record the toner image conveyed by the toner image conveying device on the medium conveyed by the medium conveying device. Additionally, the imaging system includes a control device to determine a stop state including at least one of a state where a recording check toner image is recorded on the medium, a state where a conveyance check toner image is positioned on the toner image conveying device, and a state where a formation check toner image is positioned on the toner imaging device. During the stop state, the control device stops a formation of the toner image that is performed by the toner imaging device, stops a conveyance of the toner image that is performed by the toner image conveying device, and stops a conveyance of the medium that is performed by the medium conveying device.
