Printed documents smudge easily
If you find that the ink smudges easily, there may be 
a compatibility problem between the ink and the 
paper you are using. It is recommended that you try 
using a different brand of paper.
If this doesn’t resolve the problem, try changing the 
INK SET setting to setting B (47 in the SETTINGS 
menu). Note that the ink setting will affect copies 
and faxes only (not PC prints).
