Cautions after the completion of the adjustment
The adjustment may possibly cause an increase in the amount of toner used, moiré, blurred text (small, dark text
blurred), diminished photo images or gradational images (less accurate reproduction of halftones). Therefore,
carefully perform the adjustment, while checking the copy image.
Remarks
Enter the value within the recommended value range mentioned in the procedures. Otherwise, it may cause a loss
in copier performance, including degradation in the image quality and reduction in the life of the consumables.
