Hints, tips and testing results
Xerox testing has shown the following:
•
Coated papers are very susceptible to humidity. Image mottle
(light patches in solid areas) or light images overall will occur if
paper is not kept packaged in environments with more than
60% humidity. To avoid this, keep packages sealed, use
sheets from the center of the ream, or store unused paper in a
resealable bag. Multifeeds are also much more likely with
humidity greater than 60%.
•
Two sided copying (duplexing) of coated papers may not be
recommended for your copier/printer. The most common
problems are: (1) light image patches (mottle) and deletions
on side two, especially in large halftone areas; (2) image
offsetting. Image offsetting can be caused on side two by dry
ink contamination of rollers in the fusing system when the
sheet is run through again for the side two image, or on side
one by paper-to-paper contamination in the output tray. This is
most likely to occur with high density images and will usually
appear within the first 10 copies.
Offsetting will become worse as more copies are run and can
lead to permanent damage to the fuser and pressure rolls
requiring a service call. The extent of this problem can be
highly variable and is dependent on the type of image being
run and the condition and age of the machine.
