Information processing apparatus and information storage medium with listing of error data and list acquisition

A non-transitory information storage medium for storing a program, which, when executed by a processor, causes the processor to:

• acquire a first list including a plurality of error data, each of which includes information indicating a cause of an error occurring in an image forming apparatus;
• add a number of occurrence times of each of plural cause candidates relating to the error based on the first list;
• rank the plural cause candidates depending on the number of occurrence times;
• generate a second list in which each of the plural cause candidates and a rank are associated with each other, and
• when the number of occurrence times of a first cause candidate of a first error is the same as that of a second error candidate of the first error, compare the number of occurrence times of a cause candidate that is the same as the first cause candidate with that of a cause candidate that is the same as the second cause candidate among the plural cause candidates relating to a second error different from the first error, and determine a rank of the first cause candidate and the second cause candidate for the first error based on a result of the comparison.

An information processing method, comprising:

• acquiring, by a processor, a first list including a plurality of error data, each of which includes information indicating a cause of an error occurring in an image forming apparatus;
• adding a number of occurrence times of each of plural cause candidates relating to the error based on the first list;
• ranking the plural cause candidates depending on the number of occurrence times;
• generating a second list in which each of the plural cause candidates and a rank are associated with each other, and
• when the number of occurrence times of a first cause candidate of a first error is the same as that of a second error candidate of the first error, comparing the number of occurrence times of a cause candidate that is the same as the first cause candidate with that of a cause candidate that is the same as the second cause candidate among the plural cause candidates relating to a second error different from the first error, and determining a rank of the first cause candidate and the second cause candidate for the first error based on a result of the comparison.
