5 Operational Considerations
Image Quality Expectations
Image Quality

The WorkCentre 7800 series 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 7800 series 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.

Print Expectations
Duplex (2-sided) Copying / Printing

The WorkCentre 7800 Series 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)
12x19” (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,
XPS, TIFF, JPEG, TXT) 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. Users will notice an additional 5-8 sec delay when
they first access a service. Subsequent entries into that service (including
after exiting power saver) will not incur any additional delay. 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

If AirPrint is not enabled on this product, download the install instructions
and airPrintInstall.dlm from the support and driver page for your product
at xerox.com and follow the instructions. 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.
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.

Performance Primer
Scanning Expectations

The WorkCentre 7800 Series 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.
Security Expectations
Xerox Smart Card, Kerberos, and FIPS140-3 support includes:
