Blurry or Smeared Printout
If your printouts are blurry or smeared, try these solutions:
Make sure your paper is not damp, curled, old, or loaded incorrectly in your product.
Use a support sheet with special paper, or load special paper one sheet at a time.
Make sure your paper meets the specifications for your product.
Use Epson papers to ensure proper saturation and absorption of genuine Epson inks.
Make sure the paper type setting in your product software matches the type of paper you loaded.
If you are printing on thick paper or envelopes, make sure you select the appropriate settings. In
Windows, you can also try selecting Short Grain Paper in Extended Settings.
Remove each sheet from the output tray as it is printed.
Avoid handling printouts on glossy paper right after printing to allow the ink to set.
Turn off any high speed settings in your product software.
If you print on both sides of a sheet of paper, smudges may appear on the reverse side of heavily
saturated or dark images. If one side of a sheet will contain a lighter image or text, print that side first.
Adjust the Print Density and/or Ink Drying Time settings.
Run a nozzle check to see if any of the print head nozzles are clogged. Then clean the print head, if
necessary.
Align the print head.
Clean the paper path.
Note: Your product will not operate properly while tilted at an angle. Place it on a flat, stable surface that
extends beyond the base of the product in all directions.
