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.
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 you see misregistration or “ghosting,” you need to align the print
head.
Although you can align the print head using the printer utility software, it’s
best to align from the control panel. This will do the most thorough job in
the shortest time, and it’s all automatic.
If you haven’t already done so, it’s a good idea to run a nozzle check before
aligning the print head (page 104). This ensures that the print head
alignment patterns print correctly.
Follow these steps to align the print head using the control panel:
1. Make sure the printer is turned on. Then load Epson Enhanced Matte
paper or the paper that came with the printer.
2. Press the
Menu button.
3. Press the button so you see
HEAD ALIGNMENT, then press
Menu . You see PAPER THKNS.
4. Press the
Menu button again so that *STD appears on the display.
This is the correct thickness setting for most Epson papers, including
Enhanced Matte paper.
5. Press the
Menu button to register the value, then press the button
to display
PAPER THKNS again.
6. Press the button to display
ALIGNMENT.
Note: You must use at
least a 10× eye loupe to
check the pattern.
Tip: To properly align the
print head, you can use
letter-size Epson
Enhanced Matte Paper or
Premium Luster Photo
Paper.
