  • Publication number: 20210311863
    Abstract: An anomaly factor estimation apparatus includes a training unit configured to train an anomaly detection model for performing anomaly detection based on an error of output data with respect to input data represented by a multidimensional numerical vector; a testing unit configured to input test data into the anomaly detection model, to determine whether the test data corresponds to an anomaly based on output data output from the anomaly detection model and the test data; and a factor estimation unit configured to calculate a degree of contribution to the anomaly for each dimension of the test data based on a likelihood of said each dimension, in response to the testing unit determining that the test data corresponds to the anomaly.

  • Patent number: 11112739
    Abstract: In an image-forming apparatus, a fixing device includes: a first fixing member; a heater; a motor; a second fixing member; and a pressure modifying mechanism. The second fixing member forms a nip together with the first fixing member. The pressure modifying mechanism modifies a nip pressure at a nip to one of a first nip pressure and a second nip pressure smaller than the first nip pressure. In a first case where a sheet jam occurs in the image-forming apparatus and no sheet exists in the nip, a controller performs: reducing the nip pressure from the first nip pressure to the second nip pressure; and halting rotation of the first fixing member after completed the reducing. In a second case where a sheet jam occurs in the image-forming apparatus and a sheet exists in the nip, the controller performs: the halting; and the reducing after completed the halting.
