Cautions after the completion of the adjustment
The adjustment may possibly cause degradation in the image quality. For instance, if the density of text is
increased, noise may possibly occur around the text on the copy. If the density is decreased, the text may look
faint. Therefore, carefully perform the adjustment, while checking the copy image.
