2JZ/2JX/2JV/2H7-1
1-3-51
U100
Adjusting main high voltage
Description
Controls the charger roller voltage to optimize the surface potential.
Purpose
To change the setting value to adjust the image if an image failure (background blur, etc.) occurs.
Method
1. Press the start key.
2. Select an item and press the start key. The screen for executing each item is displayed.
