Solving Problems with Paper Jams
The printer is designed to function with minimal paper jams using Xerox supported media types only. 
Other media types may cause more frequent paper jams. If supported media is jamming frequently in 
one area, that area may need to be cleaned or repaired.

•The Printer Pulls Multiple Sheets Together on page 222
•Paper Jam Message Stays On on page 222
•Duplex (2-Sided Printing) Unit Jams on page 223
•Document Feeder Jams on page 223
•Media Misfeeds on page 223
