Caution during Adjustment

If fogging appears over the entire surface even though the grid voltage are appropriate, adjust the

developer bias on the control panel. The following defects may occur if the developer bias is

lowered too much:

• Image contrast becomes low.

• Image is patchy or blurred.

• Developer carrier adheres to the photosensitive body, making it easier for scratches to occur or

the surface of photosensitive body by the cleaner blade.
