More Image Quality
Use this feature in addition to the settings selected using the Image Quality option, 
to further enhance the quality of your output.
Options:
Contrast
This option controls the differences between the image densities within the copy. 
Select a lower setting to improve the copy quality of pictures. Select a higher setting 
to produce more vivid blacks and whites for sharper text and lines.
Sharpness
This option controls the balance between sharp text and moiré (wavy patterns within 
the image). Use the up/down scroll buttons to adjust the sharpness values from 
sharper to softer, based on the quality of the input images.
Screen
This option is preset at the factory to be on with NormalText and Halftone Photo 
Original Type options.
Screen options are as follows:
Auto
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.
Special
Enhances 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.
