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 on page 94.
2. Make sure the printer is ready and the red B ink light on the printer’s
LCD panel is not on or flashing.
3. Press the
Menu button.
4. Press the button until you see
MAINTENANCE, then press
Menu .
5. Press the button until you see
PWR CLEANING, then press
Menu . Press Menu again to start the power cleaning.
6. Follow the instructions on the LCD panel to raise or lower the ink
levers.
7. When cleaning is finished and the
Pause light stops flashing, print the
nozzle check again to confirm that the head is clean.
For effective cleaning, always run a nozzle check between cycles.
If the pattern is still missing segments after a few power cleaning cycles,
turn the printer off and leave it overnight, then clean the print head
again the following morning with regular cleaning cycles. If you still see
no improvement, contact EPSON for assistance.
Caution: Don’t run a
cleaning cycle while
thick media is loaded in
the printer.
Note: You must use at
least a 10× eye loupe to
check the pattern.
