Media “trees,” wrinkles, stacks poorly, or curls 
 
FRU  Action 
Fuser 
This problem is most likely due to a worn backup roll. It causes the 
machine to run hotter than required for the media being printed. 
Excessive heat can cause media treeing problems, poor stacking, 
or curl. 
Print the menu sheet found under Utilities. 
Look at the media settings. Some, such as card stock or rough 
texture, may require a higher fuser temperature, which leads to 
more of these problems (except stacking) in plain paper. 
  Change settings using the printer driver. 
  Use the local printer setup utility (included on the CD) to 
change the NVRAM settings. 
Try a different ream of paper. Moist media has a higher tendency 
to crease (treeing) and curl.
