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.
Align the print head.
Run a nozzle check to see if the print head nozzles are clogged.
If there are missing segments in the nozzle check pattern, the nozzles may be clogged. Repeat head cleaning and the nozzle check alternately 2 times and check if the clogging has cleared.
Note that print head cleaning uses some ink.
Turn off the printer, wait for at least 6 hours, and then check if the clogging has cleared.
If the problem is clogging, leaving the printer for a while without printing may solve the problem.
You can check the following items while the printer is off.
Check that you are using genuine Epson ink cartridges.
Epson recommends using a genuine Epson ink cartridges. This product is color-adjusted based on genuine ink cartridges, so using non-genuine products may reduce print quality.
Check if the translucent film is smeared.
If there are smears on the translucent film, carefully wipe off the smear.
Make sure that there are no paper fragments left inside the printer.
When you remove the paper, do not touch the translucent film with your hand or the paper.
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.
If you turn off the printer, wait for at least 6 hours, and if print quality has still not improved, run Power Cleaning.
