1. An information processing system comprising:
an obtaining unit configured to obtain read image data generated by reading an image printed on a sheet by a printing apparatus; and
a controller configured to determine an abnormality of the printing apparatus by determining, a type of a stain that appears in the read image data obtained by the obtaining unit from among a plurality of stain types based on a learned model that has been acquired in advance through learning processing based on a plurality of pieces of read image data having known stain types,
wherein the learned model includes clusters respectively corresponding to k stain types,
wherein k is an integer equal to or larger than two, the clusters having been formed by clustering pixel value vectors of the plurality of pieces of read image data, and
wherein the controller is configured to determine that the type of the stain that appears in the read image data obtained by the obtaining unit is a stain type corresponding to a cluster to which a pixel value vector of the read image data belongs from among the k clusters of the learned model.
