Adjusting Lightness/Darkness
Making adjustments to any of the image quality controls should be done in small increments. Making large adjustments can create
image quality problems. See
About Lightness/Darkness Controls

1. In the Xerox Nuvera user interface, click the
Copy
button.
2. Select the
Basic
tab.
3. Move the slider right or left to increase or decrease (respectively) the amount of lightness/darkness.
1. In the Xerox Nuvera user interface, select
Image Quality
on the
Printer
menu.
2. To select a printer darkness value, select the
[Setup]
button and choose one of the following Print Quality modes:
3. From the Darkness slider, increase or decrease the amount of black or white applied to all pixels in the image. The values
closest to 0 are intended for small adjustments to the darkness of text and pictures. The da/-3 settings will make a
noticeable difference on text but not recommended for most pictorials.
4. From the Mode pull-down menu, select the printer emulation setting. The DocuTech 135 setting prints output that is similar in
appearance to that of the DT135 printer.
●
Best
mode -the default and recommended for most jobs, especially those on uncoated stocks. It adds or subtracts sub pixels
on the edge of the image element, text, lines, dots, solids, etc. It introduces no artifacts to lines. However, at extreme ends of
the range, contours may occur in halftones.
●
Normal
mode - the line width adjustment is identical to the Best mode and the defects are similar. In addition, it applies a
slight correction to reduce line edge scatter. The correction can be helpful for coated stocks or very smooth stocks. Typically
the adjustment is so slight it is not helpful for any black dots scattered on Mylar tabs. The amount of anti-scatter adjustment is
fixed for all darkness levels.

TIP:
It is best to proof a job when you make image quality adjustments.
NOTE:
If you notice black dots scattered at the edges of lines or text, use the Toner Saver selection with a -3 or -2 setting to
remove the dot scattering effect.
NOTE:
If you forward a job from one machine to another, the forwarded job will lose its
Printer Darkness
setting as well as
imposition and annotation attributes.
