* The smaller the setting value is, the weaker the sharpness intensity becomes. The larger the setting value is,

the stronger the sharpness intensity becomes.

Changing the values for these codes will change the sharpness intensity, when the "Sharpness" indicator in

the "IMAGE" menu is set to the center. Remember that 1 step of the indicator will increase or decrease the
sharpness intensity by 25. If the sharpness intensity of the center value is changed, each step of the
indicator will be changed accordingly. (For instance, if the center value is increased by 25 (sharper), the
value of each step of the indicator will also be increased by 25 (sharper).)

However, the range of adjustment values that is valid for sharpness level change is from -100 to +100 of

the total of the setting value of the adjustment code and that of the indicator. For instance, if the setting
value of the adjustment code is "153" (+25 from the default value), the limit of the steps in the sharp side
of the indicator is "+3". If the step is set at "+4", the image quality will not be changed.


"Sharpening the copy image" and "Minimizing moiré" are mutually contradictory. When an
adjustment is performed to sharpen the copy image, moiré may occur.

Since "+25" is assigned to the center, the image quality

remains the same even if the indicator is changed from

"+3" to "+4".
