Abstract: A server apparatus including a first communication device and a first computing device. The first communication device communicates with an image forming apparatus via a network. The first computing device includes a processor, and acts as a data acquirer, a dimension reduction processor, and a residual service life calculator, when the processor executes a first control program. The data acquirer acquires observation data of a first number of dimensions from the image forming apparatus, via the first communication device. The dimension reduction processor converts the observation data of the first number of dimensions into characteristic data of a second number of dimensions fewer than the first number of dimensions. The residual service life calculator calculates a residual service life of a replaceable unit in the image forming apparatus, on a basis of the characteristic data.

Abstract: A device diagnosis system includes an image forming apparatus, a portable terminal device, and an abnormal noise decision device. The portable terminal device collects an operating sound of the image forming apparatus, at a sound collecting position selected from a plurality of predetermined sound collecting positions relative to the image forming apparatus. The abnormal noise decision device (a) identifies a decision criterion corresponding to the sound collecting position, and (b) decides whether the operating sound contains an abnormal noise, on a basis of acoustic data of the operating sound collected, in accordance with the decision criterion identified.
