How can I tell if the computer or the product is causing a print quality problem?
You can print a nozzle check pattern to determine whether the print quality problem comes from the product itself or some other source.
If the nozzle check pattern prints with no gaps or missing sections, the product is operating properly and the problem is probably caused by your computer, cable, software, or print settings. Check for additional solutions or uninstall the printer software, then reinstall it for a USB or network connection.
If there are gaps in the nozzle check pattern, clean or align the print head.
If the page does not print, the product may have a problem. Check for additional solutions. If they don't work, contact Epson.
