WARNING: If ink gets on your hands, wash them
thoroughly with soap and water. If ink gets in your
eyes, flush them immediately with water.

Shaking the White Ink Cartridge
Checking and Cleaning the Print Head
Checking the Nozzles
The printer automatically checks the nozzles and cleans
them if necessary, but you can also check them yourself.
1Make sure roll paper or letter- or A4-size cut sheet
paper is loaded in the printer. If you need to check
the white ink nozzles, use film to ensure that the ink
is visible.
2Press Menu.
3Press until TEST PRINT is selected, then press .
4Make sure NOZZLE CHECK is selected,
then press .
5Select one of the following, then press .
• PRINT WITH WHITE INK to check all nozzles
including white ink. If the printer is in cleaning
liquid mode, white ink will be loaded first.
• PRINT NOW to check nozzles without switching
ink. If the printer is in cleaning liquid mode, no
white ink will be used.
6Press OK to start printing the nozzle check pattern.
7After the pattern is printed, use at least a 10× eye
loupe to examine it.
• If the pattern looks good, the print head is clean.
The text “CL : OK” means the cleaning nozzles
are working properly.
• If any segments are missing, or if the cleaning
nozzle status is shown as “NG” (no good), run a
cleaning cycle as described in the next section.

Checking and Cleaning the Print Head (continued)
Cleaning the Nozzles

• NORMAL CLEANING—Press OK to start the
cleaning cycle.
• CLEAN COLOR PAIRS—Press OK, select the

the cleaning cycle. Use if you know which color(s)
you need to clean; this saves ink from being used
unnecessarily to clean working nozzles.
• POWER CLEANING—Press OK to start the
cleaning cycle. Use only if three cycles of normal
cleaning doesn’t clear the nozzles.
3When cleaning is finished and the Power light
stops flashing, print the nozzle check again to confirm
that the head is clean.
You can also 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 in the
User’s Guide.
If your prints look grainy or blurry, or you see
misregistration or “ghosting,” you need to align the print
head.

You can also use Epson film or other compatible Epson
media. For best results, use the same width of paper
that you plan to print with.

then press .
4Make sure PAPER THICKNESS is highlighted, then

Before you begin a large print job, you should check your
ink levels. If one of your cartridges is low, you can replace
it before you start. Or you can wait until the ink runs
out, replace the cartridge, and then continue the job.
Checking Ink and Maintenance Tank
Levels
The easiest way to check ink levels is from the control
panel. The numbers above the ink cartridge icons
correspond to the 11 cartridge slots in the printer.
