1. An information processing apparatus that communicates with an image forming apparatus that forms an image on a sheet,
the image forming apparatus including:
a motor;
a first load;
a second load;
a drive transmission mechanism configured to selectively transmit drive of the motor to the first load and the second load; and
a control unit configured to control (i) the drive transmission mechanism to transmit the drive of the motor to the first load so that the first load is driven and (ii) the drive transmission mechanism to transmit the drive of the motor to the second load so that the second load is driven,
the information processing apparatus comprising:
an acquisition unit configured to acquire information related to an error that has occurred in the image forming apparatus, the information including timing information indicating a cumulative number of pages on which the image forming apparatus has printed images when the error occurs;
a memory configured to store the information acquired by the acquisition unit; and
a controller configured to:
determine an error part in the image forming apparatus from among a plurality of candidates including the motor, the first load, and the second load, based on first timing information and second timing information, wherein the first timing information is included in the information in the memory and indicates a cumulative number of pages on which the image forming apparatus has printed images when an error of the first load occurred, and wherein the second timing information is included in the information in the memory and indicates a cumulative number of pages on which the image forming apparatus has printed images when an error of the second load occurred; and
output a result of the determination of the error part,
wherein the controller is configured to determine the error part from among the plurality of candidates based on a difference between the cumulative number of pages indicated by the first timing information and the cumulative number of pages indicated by the second timing information.
