Nozzle Check Pattern Prints Incorrectly
If the nozzle check pattern does not print correctly, try these solutions:
• If nozzles are still clogged after head cleaning at the strongest level, leave the product turned off
overnight and check the nozzles again. If you still cannot clear the nozzles, contact Epson support.
• Clean the print head and print the check pattern again.
• If the printer has not been used for a long time, nozzles may be dried and clogged. Turn the printer on
at least once every two weeks to prevent the nozzles from clogging.
• Lint may have adhered to the platen near the print head. Clean the area using the maintenance kit.

Overall Print Quality Is Poor
If you notice that your print quality is uneven, too light, too dark, or there are vertical or horizontal lines in
the print (banding), try these solutions:
• Run a nozzle check to see if any of the print head nozzles are clogged. Then clean the print head, if
necessary.
• Align the print head.
• Make sure to use genuine Epson ink packs. Using any other type of ink pack may result in reduced
print quality.
• Use a new ink pack. Print quality declines when using an old ink pack. Use all the ink in the ink pack
before the date printed on the ink pack.
• Make sure the media settings in your RIP software or product control panel match the media you
loaded.
• If you are comparing the print result with the image on your computer screen, the colors may not
match. Since monitors and printers produce colors differently, printed colors and screen colors do not
always look the same.
• Make sure that the front cover is closed. Do not open any covers during printing. This can cause the
print head to stop abruptly, resulting in uneven color.
