Paper jam indication estimation device, paper jam indication estimation method, and recording medium

A paper jam indication estimation method that estimates an indication that a paper jam will occur in a paper feed device, the paper jam indication estimation method comprising:

• collecting a friction sound produced between sheets of paper when paper is fed into the paper feed device from a paper sheet holder holding a plurality of sheets of the paper;
• estimating, based on an output result obtained by inputting information pertaining to the friction sound into a trained model that is a machine learning model which has been trained, a presence or absence of an indication that a paper jam will occur in the paper feed device;
• and
• outputting, when the indication that a paper jam will occur is estimated to be present, a signal, to the paper feed device, that stops the paper from being fed into the paper feed device.

A non-transitory computer-readable recording medium having recorded thereon a program for causing a computer to execute a paper jam indication estimation method that estimates an indication that a paper jam will occur in a paper feed device, the paper jam indication estimation method comprising:

• collecting a friction sound produced between sheets of paper when paper is fed into the paper feed device from a paper sheet holder holding a plurality of sheets of the paper;
• estimating, based on an output result obtained by inputting information pertaining to the friction sound into a trained model that is a machine learning model which has been trained, a presence or absence of an indication that a paper jam will occur in the paper feed device;
• and
• outputting, when the indication that a paper jam will occur is estimated to be present, a signal, to the paper feed device, that stops the paper from being fed into the paper feed device.
