What should I do if the colors in my printout don't match my monitor?
Try the following:
Make sure the Black/Grayscale or Grayscale setting is not selected in your printer software.
Run a nozzle check to see if any of the print head 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.
