Remove each sheet from the output tray as it is printed.
Avoid handling printouts on glossy paper for a few hours to allow the ink to set.
If ink smears when you print on envelopes or other thick paper, turn on the Thick Paper setting. Press the Setup button, select Maintenance, choose Thick Paper, and select On.
Turn off High Speed mode in the printer software.
If you are using double-sided paper and printing heavily saturated or dark images on the front side of the paper, you may notice that smudges or marks appear on the front when you print the second side. If one side of the paper will contain a lighter image or text, print that side first to eliminate marks or smudging.
