Image Quality
Use this feature to enhance the quality of your output.
Original Type
This feature provides a convenient way to enhance the copy quality
of your output based on the type of original images you are copying.
The Normal , Text , and Halftone Photo Original Types use Auto IQ®
Image Processing to classify each pixel in the image and to apply
the appropriate image processing to enhance the copy quality for
each type of pixel. The
Photo Original Type applies a special
contrast setting and screen to the entire scanned page.
l
Normal - This is the standard setting and is appropriate for the
majority of the jobs run on the machine. It is designed to
provide high quality copies of originals that contain a mixture
of text, graphics, and pictures.
l
Text - Use this option if your original contains only text or line
art. This will result in the sharpest edges for the text and the line
art.
l
Halftone Photo - Use this option if your original is from a
magazine or other source that contains high quality lithographic
images or continuous tone photographs with text and/or
graphics. This setting will produce better pictures, but slightly
reduces sharpness for text and line art.
l
Photo - This option is specifically designed to copy continuous
tone photographs or printed halftone originals. Use this option
if your original is a photograph or halftone picture without any
text or lines. Any text or lines copied in this mode will be less
sharp than if you select any of the other
Original Types .
