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
examine the nozzle check
pattern for deflected
nozzles.
If a single nozzle in one
color remains clogged,
use SS Cleaning (see
page 93).
Maintaining and Transporting the Printer
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. To use power cleaning, the cartridges
need to be at least 50% full; replace a low cartridge if necessary. After
cleaning, you can reinsert the old cartridge.
1. Print a nozzle check pattern to make sure the print head needs cleaning,
as described on page 86.
2. Make sure the printer is ready and the B ink
control panel is not on or flashing.
3. Press the cleaning button on the control panel.
4. Press u or to select one of the following:
d
• NORMAL CLEANING—
• CLEAN COLOR PAIRS—
to clean, then press
• POWER CLEANING—
5. When cleaning is finished and the P power 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 nozzle check pattern is still missing segments or has deflections,
you can run a normal cleaning cycle up to three times. If that doesn't
work, try running a power cleaning cycle. If necessary, turn the printer
off and leave it overnight to dissolve any dried ink, then clean the print
head again the following morning with a normal cleaning cycle.
If you continue to detect a problem with the white ink nozzles, perform
a white ink refresh as described on page 86.
If you still see no improvement, contact Epson for assistance.
