USAGE GUIDELINES FOR XEROX COLOR COPIERS AND PRINTERSCOLOR MATERIALS USAGE GUIDE Visit our website at www.xerox.com 39Recycled PapersDescription and expectationsMost recycled papers are made from a combination of new pulp,waste from the paper-making process, and paper that has beenreturned by consumers for recycling. Because the nature of paperreturned for recycling is unpredictable, recycled papers are lessuniform in content and quality than papers made from entirely virginfiber.The recommended Xerox recycled papers offer the best feedperformance and image quality available. These papers undergoexclusive screening procedures to minimize the amount of harmfulinks and plastic particles in the final product. The recommendedrecycled papers will run well in Xerox copier/printers, but thereduced smoothness, formation and brightness will result indegraded image quality as compared to the benchmark Xerox24 lb (90 g/m2 ) Color Xpressions paper.Hints, tips and testing resultsXerox testing has shown the following:• Severe image quality problems are likely if non-recommendedrecycled papers are run. If you plan to use a recycled paperother than the Xerox brand, first try a small quantity to test itsperformance, then consult your local Xerox representative foragreement on its use.• The wide variation in recycled paper fibers increases thetendency for these papers to curl, which may result in jams. If anobvious curl is detected, load that paper in the (Also Called Tray5) with the curl side down for best feeding performance.• Two-sided copying with recycled papers is not recommended.The inherently poor image quality of recycled papers onlybecomes worse when the second side is run.• To avoid making a marginal material worse, all recycled papersshould be stored in sealed packages when not in use. Imagequality on exposed papers will degrade even more as humidityincreases.
