Operation Manual

❏ Power cleaning consumes more ink than normal
head cleaning. Check the remaining ink level in
advance, and prepare a new ink cartridge before
you start cleaning if the ink is low.
❏ If the nozzles are still clogged after performing
power cleaning, turn off the printer and leave it
overnight or longer. When left for some time, the
clogged ink may dissolve.
If the nozzles are still clogged, contact your dealer or
Epson Support.
❏ If a Cleaning Error message is displayed on the
screen, see the following section to check the cause
and how to solve the problem.
