Overview


A "tree" is a paper defect caused when the paper buckles and forms a tiny ripple that is "ironed" in by the fuser. Humid environments are more likely to cause the paper to have a "wave" or "ripple" to the leading edge that generally lead to the trees. 

 

 


 

Print sample


A tree can be in various sizes. See sample printout below:
