Preventing and Clearing Paper Jams
To reduce the occurrence of paper jams, follow the guidelines and instructions in Printing 
Basics on page 41. It includes information about supported paper and media, guides for 
usage, and instructions for properly loading paper in the trays.
Caution: When removing jammed paper, make sure that no pieces of torn paper are left in 
the printer. A piece of paper remaining in the printer can cause a fire. If a sheet of paper is 
wrapped around the heat roller, or when clearing a jammed paper that is difficult or 
impossible to see, do not try to remove it by yourself. Turn off the printer immediately, and 
refer to the Xerox Support website, www.xerox.com/office/6128MFPsupport
.
Wa rni n g:  The fuser and the surrounding area are hot and can cause burns.
