5. Operational Considerations
Print / Image Quality Expectations
Duplex (2-sided) Copying / Printing
The WorkCentre 7970/7970i can automatically perform two-sided
(duplex) copying or printing on media size up to 12x19” (SRA3) and
non coated 220 gsm paper or coated 169gsm paper.
Manual duplex can be performed on media up to 110 lb Cover
(300gsm) 1
2x19” (SRA3) from Tray 5 (Bypass).
Full duplex print productivity is achieved except when paper exits to
the top center tray.
Image-to-Paper Registration
Printing registration specifications for 8.5 x 11” (A4) size media
are ±1.5 mm (side 1), ±1.9 mm (side 2) along the lead edge and
±2.0mm (side 1), ±2.4mm (side 2) mm along the side edge from
Trays 1-4. Lead Edge is ±2.2 mm and Side edge ±3.0 mm for
bypass tray.
Skew registration specification from side to side feeding for 8.5 x
11” (A4) size media from Tray 1-4 is ±3 mm on simplex side and
±4 mm on duplex side. Bypass tray skew is ±4 mm.
USB Print
USB Media Print enables walk-
up users to print “Print-Ready” files
PDF, JPEG, TIFF, PS, XPS (requires XPS Print Kit), PCL files,
directly from most standard (FAT-32 formatted) USB Thumb
Drives.
Files are sent directly from the USB drive to the print controller.
Power On time
Power on time from cold-boot to the display of the main All services
screen may take three minutes. This is designed to improve the
availability of the first screen as the subsequent services are loaded
when first accessed.
Print Around
The Print Around feature holds a job needing additional resources
(such as a different paper size) and prints the next job in queue.
This function allows the device to keep working, while making sure
jobs are printed correctly.
Apple AirPrint
AirPrint-enabled ConnectKey devices work with iPad (all models),
iPhone (3GS or later), and iPod touch (3rd generation or later),
running the latest version of iOS. For printing from a Mac, the device
must be running Mac OS X 10.7 or later to support AirPrint. The
device submitting the AirPrint job must be on the same subnet as
the printer. To allow devices to print from different subnets,
configure your network to pass multicast DNS traffic across subnets.
Image Quality
The WorkCentre 7970/7970i is designed to produce consistent
uniform looking color and monochrome prints and copies in the
product’s specified Average Monthly Print Volume range.
The WorkCentre 7970/7970i is designed to produce a uniform
image. Image Quality is subjective and can be impacted by
lighting, and is strongly influenced by paper (consult the
Recommended Materials List).
Color Management and Print Resolution
The appearance of the document displayed on the computer
monitor screen may not match the output print due to the
following reasons:
The range of colors that can be produced in print is different than
the range of colors that can be displayed on a computer display.
Different display technologies have different reproductions of
color
Printed colors appear differently under different light sources.
The customer is responsible for calibrating the WorkCentre
using the provided copy and print calibration routines.
The Postscript and PCL drivers contain the ability to adjust the
print quality. Image adjustments include Color correction
modes, ability to render images at either 600x600 (contone or
binary) or 1200x1200 dpi (binary only). All images are marked at
2400 x 1200 dpi. ICC profiles can adjust how RGB and CMYK
objects are reproduced. There are differences between the PS,
XPS and PCL driver based on PDL image-path limitations.
When the print drivers "Color" output mode is selected,
grayscale images in MS Office applications may print using
composite grays, which contain a visually neutral combination of
C, M, Y and K.
Pages are not guaranteed to print and bill as monochrome
unless the "Black and White" output color mode is selected in
the print driver.

Network Connectivity Expectations
USB Wireless Network Adapter
Your Xerox Device can be equipped with an optional Xerox USB
802.11b/g/n (2.4GHz) Wireless Adapter to enable WiFi
connectivity. When utilizing this Xerox Device over WiFi, it is
important to understand the performance impacts that may result
from WiFi technology. Compared to a wired Ethernet connection,
WiFi performance varies significantly due to many factors that
are specific to wireless technology.
Some of these factors include: WiFi LAN Overhead, Proximity to
Access Point (AP) and Physical Obstacles (i.e. Signal Strength),
Network usage / AP Loading and Radio Frequency (RF)
interference.

Scanning Expectations
The WorkCentre 7970/7970i supports scan to network folder,
Scan to USB, Scan to Mailbox, Scan to Home and Scan to email
functionality as standard.
Scan Resolution
The maximum image scan resolution is 600 dpi. The default
scan resolution is set to 200dpi.
Note: Several resolution settings are selectable via the 8.5 inch
User Interface touch panel. Lower resolutions will result in files
that are smaller in size thereby reducing network traffic.
When scanning the OCR processing, image compression, file
formatting and file transfer operations all continue after the job
has completed scanning by the scanner.
Heavy print usage may delay the processing of scan jobs.
