An information processing apparatus includes processing circuitry. The processing circuitry detects an abnormality in an image reading apparatus from a first spectral reflectance and a second spectral reflectance, the first spectral reflectance being generated based on data read from a reference white plate installed in the image reading apparatus, the second spectral reflectance being generated before generation of the first spectral reflectance, and identifies a cause of an abnormality in the image reading apparatus in a case where the processing circuitry detects the abnormality.

Information processing apparatus, abnormality detection method, storage medium, and information processing system

A color chart is for evaluating printing quality of an image forming apparatus. The color chart includes identification information and a color evaluation patch. The identification information is on an image forming apparatus on which evaluation of printing quality is to be performed. The color evaluation patch includes a plurality of color patches for performing evaluation of printing quality on the image forming apparatus indicated by the identification information.
