If you still see white or dark lines or missing nozzles in your
printouts, even after cleaning the print head several times, you
can run a Power Cleaning.
If you do not see improvement after running a Power Cleaning,
turn off the product and wait at least 12 hours before running
another Power Cleaning.
Caution:
Running a Power Cleaning consumes a lot of
ink, so you should run it only if necessary. Make sure each ink
tank is at least one-third full before running a Power Cleaning, or
it may damage the product.
Caution:
Power Cleaning may cause the ink pads to reach
their capacity sooner. When an ink pad reaches the end of its
service life, the product stops printing and you must contact Epson
for support.
