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. Let your prints dry separately for at least 12 hours before framing or placing them in protective sheets. If you need to stack them, place a sheet of plain paper between each print.
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.
