When copying on the back side of a preprinted sheet
IMPORTANT
When loading paper into the stack bypass, align the paper stack neatly between the slide guides.
If the paper is not loaded correctly, a paper jam may occur.
NOTE
• If there are instructions on the paper package about which side of the paper to load, follow those
instructions.
• When the paper is loaded into the stack bypass, the side facing up is the one printed on.
• If problems, such as poor print quality or paper jams occur, try turning the paper stack over and
reload it.
• For more information on the print direction of preprinted paper (paper which has logos or
patterns already printed on it), see "Relationship between Original Orientation and Preprinted
Paper Output Chart," on p. 9-21.
