The time periods between energization of an optics clutch and activation of a scan switch at the end of scan position and between de-energization of the optics clutch and actuation of the scan switch at the home position are provided. Representations of the time periods are continuously displayed during a copy run. The last timing periods of a copy run are temporarily stored until the next copy run. Upon entering a diagnostic mode, the machine will produce a copy in the normal manner and display a number corresponding to the forward scan and return scan or flyback time periods. Through suitable conversion, the scan time in milliseconds can be provided.
