Selected FAQ

Q:
What should I do if the quality of my printout is unacceptable?
A:
If the image looks fine on your computer screen but not when printed, make sure you're using the latest driver version for your printer. Also, make sure you select the correct quality option, paper type, paper size, and orientation setting in the printer software for your print job. If that doesn't help, and the image also looks incorrect on screen and you're using Epson Scan, see the solutions below for your problem.

White or Dark Lines in Printout
  • Run a print head nozzle check to see if any of the nozzles are clogged. Then clean the print head, if necessary.


  • Make sure the paper type setting matches the type of paper you loaded.


  • Make sure you loaded the printable side of the paper facedown in the cassette.


  • Turn off any high speed settings in your product software.


  • Align the print head.


  • You may need to replace the ink cartridges.

Blurry or Smeared Printout
  • Make sure your paper is not damp, curled, old, or loaded faceup in the cassette (the printable side should be facedown).


  • 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 matches the type of paper you loaded.


  • 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 print head nozzle check to see if any of the nozzles are clogged. Then clean the print head, if necessary.


  • Align the print head.


  • Clean the paper path.

Faint Printout or Printout Has Gaps

  • The ink cartridges may be old or low on ink, and you may need to replace them.


  • Make sure the paper type setting matches the type of paper you loaded.


  • Make sure your paper is not damp, curled, old, or loaded faceup in the cassette (the printable side should be facedown).


  • Clean the paper path.

Grainy Printout

  • Make sure you loaded the printable side of the paper facedown in the cassette.


  • Select a higher print quality setting and turn off any high speed settings in your product software.


  • Run a print head nozzle check to see if any of the nozzles are clogged. Then clean the print head, if necessary.


  • Align the print head.


  • You may need to increase the image resolution or print a smaller size; see your software documentation.


Incorrect Colors
  • Make sure the Black/Grayscale or Grayscale setting is not selected in your printer software.


  • Run a print head nozzle check to see if any of the nozzles are clogged. Then clean the print head, if necessary.


  • The ink cartridges may be old or low on ink, and you may need to replace them.


  • Your printed colors can never exactly match your on-screen colors. However, you can use a color management system to get as close as possible. Try using the color management options in your printer software.


  • For best results, use genuine Epson ink and paper.
