5 – 5 Xerox DocuColor 3535 Printer/Copier
NOTE: Do not load paper above the fill line of the paper tray edge
guides.
NOTE: Fan the desired paper before loading it into the Tray.
Straighten the paper stack each time the paper tray is opened.
Close the paper tray slowly to avoid shifting the paper stack. This
ensures that the paper is in the correct position when the paper
tray is in the operating position.
If paper feeding or copy curl problems occur, flip the paper over in
the tray and make the copies again. If the performance improves,
continue to load the paper in this manner. Testing has shown that
paper handling and copy performance vary with room
temperature, humidity, paper quality, image area on copies, etc.
All of these variables interact and, in some cases, you must
decide which paper loading method works best.
NOTE: Coated papers are very susceptible to humidity. Multifeeds
are much more likely with humidity greater than 40%.
Environmental conditions may require that coated paper be fed
one sheet at a time from Tray 5 (Bypass).
