Checking and Cleaning the Print Head
If the nozzles are clogged, the printouts become faint, there is visible banding, or unexpected colors appear. When
print quality has declined, use the nozzle check feature and check if the nozzles are clogged. If the nozzles are
clogged, clean the print head.

Important:
❏ Do not open the scanner unit or turn off the printer during head cleaning. If the head cleaning is incomplete, you
may not be able to print.
❏ Because print head cleaning uses some ink, clean the print head only if quality declines.
❏ When ink is low, you may not be able to clean the print head. Prepare a new ink bottle.
❏ If print quality has not improved after repeating nozzle check and head cleaning three times, wait for at least 12
hours without printing, and then run the nozzle check again and repeat the head cleaning if necessary. We
recommend to turn off the printer. If print quality has still not improved, contact Epson support.
❏ To prevent the print head from drying out, do not unplug the printer while the power is on.
