Density Settings
This section describes how to adjust the density settings for the Pale mode
Generation Copy mode, and Text mode.
SP4904 3 is used to switch the density characteristics to binary digital processing
for black and white originals to achieve better balance between text and images,
correct shadows that appear around text in handwritten documents, to enhance
documents written in pencil, or to achieve stark contrast when copying blueprints,
building plans, etc.
SP4903 3 Density Setting for Low Density Original Mode
Settings Density Characteristics
0
Selects γ normal density (Default).
1
Digitizes to near binary image.
SP4904 4 is used to switch between normal density and better reproduction of
areas with graduated fill in originals copied in the Generation Copy mode. To
improve the appearance of graduated fill areas of high density, set to “1” so the
process can ignore black and more accurately reproduce areas with graduated fill.
For example, the “1” setting is ideal for copying Generation Copy originals of
medical charts that contain images of internal organs.
