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 the 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 maintenance
box to reach its capacity sooner. When the maintenance box is full,
you need to replace it to continue printing.
