4. Making Copies

More Image Quality

Contrast controls the differences between the image densities

within the copy. Lower contrast settings improve the copy quality of

pictures by reproducing more detail in light and dark areas of the

original. Higher settings produce more vivid blacks and whites for

sharper text and lines but less detail in pictures. Use the scroll

buttons to adjust the contrast values.

Sharpness controls the balance between sharp text and moiré

(undesirable patterns within the image). Generally, sharpness is

used to enhance the copy quality after evaluating the output. Use the

scroll buttons to adjust the sharpness values from sharper to softer

after you view your output.

High sharpness settings provide the sharpest text and lines, but

increase the likelihood of moiré.

Screen

This is only available for the Normal, Text, and Halftone Photo

Original Types.

The Auto setting is preset at the factory to be on when Normal, Text,

or Halftone Photo is selected. It eliminates the risk of blotches or

small areas that have a different texture or pattern appearance than

the surrounding area, but produces a slightly grainier picture than if

Special is used.

The Special selection can be utilized to enhance continuous tone

photographs or high frequency halftone images. It is used to create

smoother, less grainy output for continuous tone and halftone

images, but the risk of blotchy copy quality defects is higher.
