Once the cartridge is installed, the printer returns to its
state.
Paper Type and Banding
Banding can be caused by several problems, such as clogged
print head nozzles or a misaligned print head. It can also be
caused by using a paper that is not defined in the Epson
printer driver or in a third-party RIP. To correct this problem,
make sure you select the correct paper type in the driver. See
"Selecting the Correct Media Type Setting" in the User's
Guide or Printer Guide.
If your paper type is not defined, use the printer's menu
system to create a custom paper type. See "Optimizing the
Settings for Your Paper" in the User's Guide or Printer Guide.
Checking and Cleaning the Print Head
If your printed image shows a color shift or horizontal lines,
you should check the print head to see if any nozzles are
clogged or deflected. If necessary, the printer will
automatically run a cleaning cycle to clear the nozzles.

The nozzle check pattern is printed and automatically read. If
the printer finds clogged nozzles, it runs a cleaning cycle.

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. See User's Guide for instructions.

power cleaning.
6. Follow the instructions on the LCD display to raise or lower
the ink levers.
7. When cleaning is finished and the
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 or has deflections
after a power cleaning cycle, 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.
Aligning the Print Head
Aligning the print head is the most important thing you can
do to ensure the best print quality. If banding appears on your
prints, if they look grainy or blurry, or if you see
misregistration or "ghosting," you may need to align the print
head.
Although you can align the print head using the printer utility
software, it's also easy to align from the printer's control panel.
This will do the most thorough job in the shortest time, and
it's all automatic.
button
If you haven't already done so, it's a good idea to run a nozzle
check before aligning the print head (see User's Guide). This
ensures that the print head alignment patterns print correctly.
