11 Enters the copy aging mode to allow the following operation and setting.
Display
Use "→" key to select, and press PSW to determine. Aging is started.
12 Copying is made without process control operation. This simulation is used to know whether the trouble
is in the process section or in the other section when F2 trouble occurs.
