3. Select one of the following, then press OK :
• ON: PERIODICALLY —The printer periodically checks its nozzles
and runs a cleaning cycle if necessary (default).
• ON: EVERY JOB —The printer automatically checks its nozzles
and runs a cleaning cycle if necessary before each print job. This

cleaning cycles.

Running Cleaning Cycles
You can run several types of cleaning cycles from the control panel (or from
the Epson LFP Remote Panel2): normal cleaning, power cleaning, and
cleaning each pair of ink colors.
Run the power cleaning only if the normal cleaning process is not sufficient
to clear the nozzles. 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 on page 150.
2. Make sure the printer is ready and the red B ink Check light on the
printer’s control panel is not on or flashing.
3. Press r Menu .
Caution: Don’t run a
cleaning cycle while
thick media is loaded in
the printer.
