An image processing apparatus detects a failure that has occurred, and determines whether or not the location at which the failure has been detected is in an accessory device attached to the body of an image processing apparatus. When the location at which the failure has been detected is in an accessory device, the image processing apparatus receives video data that shows a handling procedure for eliminating the failure that has occurred in the accessory device from a video distribution server and stores the data in a storage unit, and reproduces and displays the video data on a screen. Then, when the image processing apparatus detects that the above described failure has been eliminated, it erases the video data displayed on the above described screen from the storage unit.
