Paper curl is caused by a variety of factors. Many papers tend to curl toward one side after toner is
applied and fused. For some paper products, paper curl variability may be evident from batch to
batch and even from ream to ream.
The DocuColor 5000AP has an automatic curl control system that uses a number of variables to
adjust the amount of pressure applied by different decurlers in an effort to reduce as much curl as
possible from printed output. Default settings are programmed in the system based on equipment
design parameters; however, the default settings may not be appropriate for all papers.
Most of the papers designed for xerographic use indicate the preferred printing side with an arrow on
the ream label. Follow the manufacturers' suggestions for first image side, and load paper with the
arrow pointing up for onboard trays 1 and 2, as well as Secondary Feeder Module (SFM) trays 3 and
4. If the output prints have too much curl, first try flipping over the stack of paper in the paper tray
being used.
If flipping the stack of paper over does not resolve the curling problem, enter the Tools Mode and
manually select a new decurler setting for the paper. Refer to the DocuColor 5000AP System
Administration Guide for information on how to access Tools Mode and the Decurler Setup screen.
The four pre-programmed decurler settings are named A, B, C, and D and refer to a set of
parameters that characterize how a particular paper interacts with the DocuColor 5000AP decurling
system. Select a different setting for the tray, type, and weight of paper with a curling problem, then
exit Tools Mode and re-run a few sheets using the new setting. A difference in behavior should be
visible, but if output curl remains unacceptable, try additional settings until desired output is achieved.
Six additional settings (E1-E6) provide additional adjustment flexibility based upon actual output curl
measurements.
To use settings E1 – E6, you must first program these settings to match paper grade, type, area
coverage, and environmental conditions. Refer to the DocuColor 5000AP System Administration
Guide for instructions on programming these settings.

DocuColor 5000AP performance is tightly linked to good media selection and adequate job creation.
For particular applications, using coated materials will improve image quality.
The DocuColor 5000AP can be used to produce black and white documents as well as color.
Because of the way black and white documents are processed and fused, you will need to run a fine
grain paper when running jobs with blocks of solid black. For these jobs, try using Xerox Digital Color
Elite / Select Gloss or Silk Coated paper in the USA and Canada and Xerox Colotech + Gloss or Silk
Coated in Europe.
Another way of ensuring fine quality solid black images is to change grayscale images to duotones or
process black. This allows the machine to apply its optimum imaging capabilities to the file.
Also, the 150 cluster dot screen, available in the print driver, can be used to soften a grayscale image
and to create specific customer effects. By default, the system uses a 200 cluster dot screen to
achieve its crisp image quality.
