Try the solutions in the order shown, until you solve the problem.
Make sure you match the paper type loaded in the printer and the paper type selected on the printer to the paper type setting in the printer driver.
Use a higher quality setting on the control panel or in the printer driver.
Align the print head.
Make sure the print head nozzles are not clogged.
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.
Make sure you are using 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.
Check if the translucent film is smeared.
If there are smears on the translucent film, carefully wipe them off.
Make sure 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.
Make sure the paper is loaded with the printable side facing up and not curled.
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.
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.
If you cannot solve the problem by checking the solutions above, contact Epson support.
