Try the following problems in order starting at the top until you solve the problem.
Make sure you match the paper type loaded in the printer and the paper type set on the printer to the paper type settings in the printer driver.
Use a higher quality setting on the control panel or the printer driver.
Reinstall the ink cartridges already installed in the printer.
Reinstalling the ink cartridges may clear clogging in the print head nozzles and allow the ink to flow smoothly.
However, because the ink is consumed when the ink cartridge is reinstalled, a message asking you to replace the ink cartridge may be displayed depending on the amount of ink remaining.
Run a nozzle check to see if the print head nozzles are clogged.
If the nozzles are clogged, clean the print head.
Note that print head cleaning uses some ink.
Check that you are using genuine Epson ink cartridges.
Try to use genuine Epson ink cartridges. This product is designed to adjust colors based on the use of genuine Epson ink cartridges. The use of non-genuine ink cartridges may cause print quality to decline.
Make sure that there are no paper fragments left inside the printer.
Check the paper.
Check if the paper is curled or loaded with the printable side facing up.
Make sure that you are not using an old ink cartridge.
For best results, Epson recommends using up ink cartridges before the best before date printed on the package, or within six months of opening the package, whichever is earlier.
