9. Gradation processing
In case of color copying, this function switches the type of gradation processing depending on the
copy mode: A type which selects the printer characteristics giving the priority to resolution such as
for text data, and another which selects the printer characteristics giving the priority to reproducibility
of gradation such as for photographic images.
In case of black copying, this function selects the gradation processing which reproduces the
halftone image such as photograph more precisely. Also the gradation processing which makes text
data clearer is selected in black copying mode.
10.Compression/expansion
To lessen the data amount of the color image signals, this function effects the compression/
expansion on the data.
11. Blank page detection
This function determines whether an original is blank or not with the pixel colors of its image data
input by the scanner or the printer. If the original is determined as blank, it is printed out as a blank
page.
12.Outside erase

image because the Platen Cover (optional) is not fully closed. This function erases this area and
prints only the required image data.
13.Smoothing processing
This function removes jaggy and smooths character outline of images and output them.
14.Scanner high quality image processing

image quality.

quality.
