Power Cleaning
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.
