Xerox Nuvera 288 Perfecting System
For the
dC0604 PE Registration Setup - use to align and register the image on side 1 with the image on side 2.
dC0965 System Image Quality Xerographic Balance - use to adjust the lightness and darkness values between
the two print engines. If you notice the images output from one print engine appear lighter than the other print
engine, run this image quality matching diagnostic routine before contacting Service. The system performs an
automatic check and prints 10 pages (side 1 printed from print engine A1 and side 2 printed from print engine A2).
Visually inspect and compare the image quality and select whether side 1 or side 2 is lighter, or no difference
between the sides. The routine will increase the toner mass on the photoreceptor belt if the user indicates that one
side is lighter than another.
System: System Optimization Customer Setup
Enable or disable the following optimization switches as needed for the job.
Wide Stocks (9.0-9.5" process direction) - Optimize Print Speed - for the Xerox Nuvera 288 Perfecting System
only, enable this feature if you are printing stock greater than 9.0 inches and up to 9.5 inches wide. The common
book sizes for such a job is 9.25 inches and 9.5 inches wide. This feature allows this size paper to print at 240 ipm
instead of 192 ipm thereby optimizing the print speed for this workflow. This feature is not available on
configurations with a BFM.
Heavy-Weight Stock Jobs - Enhance Image Permanence (EIP) - select if printing media with challenging fix
characteristics, such as heavy rough stock and some coated stock. When EIP is enabled, an EIP icon displays in
the status/mode indicator area of the FreeFlow Print Server user interface indicating that this mode is in effect.
Place the mouse over the icon to display the tool tip for how and when to exit this mode. Selecting EIP runs the
fuser at a constant, higher temperature and increases image permanence on heavyweight paper. Since this higher
temperature may cause waves and curl in lightweight stocks, and degrade output stack quality, deselect this
feature and use AIP mode when not printing on heavyweight stock.
Automatic Image Permanence for All Stock Weights (AIP) - AIP is the preferred mode. Use this routine to
adjust the fuser temperature accordingly based on the programmed job information.
NOTE: Automatic Image Permanence (AIP) is dependent on how the user programs media characteristics
into the stock library or into each feed tray.
Spending a few moments to correctly program the media is important to getting the optimal performance
from your Xerox Nuvera system.
The Xerox Nuvera runs in Nominal Mode if neither EIP or AIP is selected. Nominal Mode runs at a mid-level
fusing temperature that is satisfactory for most media.
Light-Weight Stock Jobs - Optimize Image Quality - use to improve image quality problems on lightweight stock
resulting from deletions on large format media with low area coverage. These deletions are typically only seen on
side 2 of 2-sided jobs. Do not use with heavyweight stock and use only when directed to do so by a Xerox
representative. Do not select this feature and EIP mode at the same time.
Reduce Up-Curl for 2-Sided Jobs - for the EA Production System, enable when there is excessive upcurl in the
output stacks. The system prints side 2 first and then side 1 to avoid the sheet being inverted after the second
image. This causes the output to have down curl instead of up curl. Note that this selection does not apply to jobs
programmed with ordered stock and 3-hole punch stock. If used, the system ignores the Reduce Up-Curl feature
and prints side 1first.
Cycle Up Purge Enabled - not available to the user. This feature is used only by a Xerox technical representative.
Feed Until Empty Algorithm - when enabled, the system empties stock from the secondary feed tray in use
before switching back to the primary tray.
Pass Through Mode - for the Xerox Nuvera 288 Perfecting System only, from this drop-down menu, select the
specific print engine (Print Engine A1 Only or Print Engine A2 Only) that you want the system to use to continue
printing 1-sided or 2-sided jobs when the other print engine is shut down. Pass Through Mode is in effect and
paper will simply pass through the idle print engine. Select Off to disable Pass Through Mode and allow paper to
print using both print engines.
Crash Recovery: Last Sheet Delivered Not Known - If the system crashes while printing a large job and you
need to restart FreeFlow Print Server and reboot the system, the system will attempt to perform a job recovery. If
the system knows the last sheet delivered to the finisher, the settings for this feature are not required and the job is
recovered automatically. However, in case the system crash affects the finisher's ability to correctly detect the last
sheet and automatically perform job recovery, use this feature to select either [Use Best Guess](default) or [Do Not
Recover Job] from this drop-down menu to indicate the type of job recovery to use. Select [Use Best Guess] if the
last sheet delivered is not known and you want the system to still attempt to recover the job. The system displays
messages to check the output for duplicate pages or missing sheets. Select [Do Not Recover Job] if you want to
recover the job, perform paper clearance and resubmit the job manually. The job remains unrecoverable in the
inactive queue. This feature is not used when the system is only experiencing jam recovery or jam faults.
NOTE: After a system reboot (due to power outage/tripped breaker, kernel panic, or power cycle using the white
button), if the job does not recover correctly, the recommended procedure is to open the Job Properties and set the
Pages to Print values to the range of pages remaining to be marked.
, perform the following routines as needed.
