How the WorkCentre 7970 Color
Multifunction Printer Exceeds the
Print Quality Requirement
Color Registration and Accuracy
With an ASIC driver to control the light intensity
of the LEDs in each printhead, HiQ LED offers
better dot-to-dot intensity and timing control,
and produces more precise color registration.
HiQ LED handles mis-registration issues
automatically, simultaneously and continuously,
from LED to LED. In fact, tests show that HiQ
LED technology corrects color mis-registration
even better than comparable laser printers.
Plus, true Adobe

Printhead Technology and Image Resolution
The WorkCentre 7970 Color Multifunction
Printer features the Xerox
®
HiQ LED printhead,
which offers major improvements in image
quality.
The “brain” behind the entire print-head process
is our new application specific integrated circuit
(ASIC) driver chip. This high-performance driver
precisely controls the intensity and timing LEDs
in each printhead to achieve 1200 x 2400 dpi
resolution – print quality that’s equivalent to,
and often better than, comparable laser systems.
By continually and automatically monitoring
information about each LED, the ASIC driver can
adjust each diode’s light intensity and timing.
This ensures uniformity across the entire LED
array – and produces consistently high print
quality without compromising the printer’s high-
speed output. Whether printing spreadsheets,
presentations or customer collaterals, the
WorkCentre 7970 delivers truly impressive results.
Plus, Xerox
®
EA Ultra Low-Melt Toner –
chemically grown to produce the market’s
smallest, most uniformly shaped particles –
delivers sharper clarity, excellent shadowing
and outstanding fine-line detail.
Unique Color Control
Our “Color By Words,” a powerful-yet-intuitive
color technology, takes the guesswork out of
optimizing your color print jobs. With Color By
Words there is no need to manipulate source
files. Users simply select the desired color
modifications from a drop-down list – such as
“green colors a lot more green” or “red colors
a lot more saturated” – and the image is
automatically adjusted.

Color By Words: Unique Color Control
Have you ever wanted to change the color
of one object or area in a printout without
affecting the rest of the page? With the
Color By Words feature there is no need
to go back to square one and manipulate
source files. You simply select the desired
color modifications from a drop-down
list, and Color By Words will adjust your
printout.
