Maintenance necessity estimation apparatus and non-transitory computer readable medium

A maintenance necessity estimation apparatus comprising:

• a storage unit that stores in advance an estimation model that is constructed in advance using a value corresponding to a first transit time from a predetermined time point in each image processing apparatus that includes a transport path on which paper is transported and a drive member that is disposed along the transport path and is operated to transport the paper to a time point when the paper passes through a predetermined position on the transport path, and using first feature information indicating a feature of the paper, as input information, which are acquired from the plurality of image processing apparatuses, and using, as output information, information corresponding to transport fault information relating to a transport fault of the paper due to the drive member, which is acquired from the plurality of image processing apparatuses, and estimates first necessity information indicating a degree of necessity of a maintenance work with respect to the drive member in accordance with the output information;
• an acquisition section that acquires a second transit time and second feature information of an image processing apparatus which is an estimation target of second necessity information;
• and
• an estimation section that estimates necessity information of the image processing apparatus which is the estimation target using, as input information, a value corresponding to the second transit time and the second feature information acquired by the acquisition unit, using the estimation model stored in the storage unit.
