Quality menu details (continued)
Menu selection Purpose
Color Balance To provide users with the
ability to make subtle color
adjustments to printed
output by increasing or
decreasing the amount of
toner being used for each
color plane individually.
Color Samples To assist users in selecting
colors to be printed. Users
can print color samples
pages for each of the RGB
and CMYK color
conversion tables used in
the printer.
The color samples pages
consist of a series of
colored boxes along with
the RGB or CMYK
combination that creates
the color observed for
each particular box. These
pages can be useful in
helping users decide which
RGB or CMYK
combinations to use in
their software applications
to create the desired
printed color output.
The printer Embedded
Web Server interface,
which is only available on
network models, offers
users more flexibility. It lets
users print Detailed Color
Samples.
Manual Color To let users customize the
RGB or CMYK color
conversions applied to
each object on the printed
page. Color conversion of
the data specified using
RGB combinations can be
customized based on
object type (text, graphics,
or image) through the
printer operator panel.
