Operation
Operation/
Procedure
When the [EXECUTE] key is pressed, it is highlighted and the main motor rotates to start the drum marking
sensor and the image density sensor gain adjustment. (The adjustment is automatically performed.)
After completion of the adjustment, the [EXECUTE] key returns to the normal display and the main motor stops.
At that time, the gain level of each sensor is displayed.
If the adjustment is not completed properly, the ERROR display is shown.
