Abstract:
1. An abnormal sound diagnostic apparatus for an image formation device to perform a printing processing having a series of sequential operation steps of forming a latent image corresponding to an image, developing the latent image and transferring the developed image on a paper sheet, fixing the transferred image on the paper sheet, and delivering the paper sheet, the diagnostic apparatus comprising: a storing section that stores diagnostic procedure information in which a series of sequential operation steps of the printing processing are divided into functional units of a paper delivering function and an image formation function and an operation order of the divided functions are specified; a first drive control section that sequentially drives drive mechanisms according to the operation order of the respective functions in the diagnostic procedure information stored in the storing section, each of the drive mechanisms being respectively driven according to the series of the sequential operation steps of the functions; a first receiving section that receives confirmation information whether or not an abnormal sound occurs when the first drive control section drives the drive section, the confirmation information being inputted at each time of driving of the drive mechanisms by the first drive control section; a second drive control section that independently and sequentially drives each of the drive mechanisms for each operation step, and stops the drive mechanisms being driven by the first drive control section when the first receiving section receives the confirmation information that an abnormal sound occurs, each of the drive mechanisms being respectively driven according to the series of the sequential operation steps of the functions; a second receiving section that receives the confirmation information whether or not an abnormal sound occurs, the confirmation information being inputted each time the second drive control section drives each of the drive mechanisms according to each operation step of the functions; and an identifying section that identifies a drive mechanism being driven by the second drive control section as an abnormal sound occurring location when the second receiving section receives the confirmation information that the abnormal sound occurs.
