Abstract
A diagnostic program determines whether the machine is in a proper or improper operational state, and the scanning device is moved to a predetermined position in response to the positioning program after the entry of the key inputs by the entry program, and a copying operation is then enabled. The key entry program is executed after the machine starts, and the positioning program is executed before the start of the scanning device and after the key input entry, wherein the scan is inhibited from exposing the recording medium when the diagnostic program determines that the state of the machine is improper, or when the positioning program determines that the scanning device is not in the predetermined position. Also, the scan is enabled for exposing the recording medium when the diagnostic program determines that the state of the machine is proper and the positioning program determines that the scanning device is in the predetermined position.
