Running a Power Cleaning Cycle

You can run a power cleaning cycle from the control panel if the normal
cleaning process is not sufficient to clear the nozzles. However, the power
cycle uses a large quantity of ink, so it is recommended only as a last resort.
The cartridges need to be at least 50% full to use power cleaning. You may
need to replace a low cartridge to run the cleaning cycle. After cleaning, you
can reinsert the old cartridge.
1. Print a nozzle check to make sure the print head needs cleaning, as
described above.
2. Make sure no paper is loaded and the red B ink light on the printer's

You may need to run the cleaning cycle several times to get a clean
nozzle check pattern. For effective cleaning, always run a nozzle check
between cycles.
If the lines in the pattern are still missing dots after several cleaning
cycles, turn the printer off and leave it overnight, then clean the print
head again the following morning. If you still see no improvement,
