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 maintenance
box to reach its capacity sooner. When the maintenance box is full,
you need to replace it to continue printing. If the ink levels or
the free space in the maintenance box are insufficient for Power
Cleaning, you cannot run this feature.
