Cleaning Cycle, as described in the next section.
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.

levers.
