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 9). 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.
Tip:
To properly align the print head, you can use letter-size Epson
Enhanced Matte Paper or Premium Luster Photo Paper.
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.
7. Press the
Menu button to display AUTO, then press the
Menu button again. You see UNI-D (uni-directional).
This is the type of alignment to start with.
8. Press the
Menu button again to start the alignment
process.
It takes about 7 minutes to run the automatic uni-
directional head alignment. The printer’s white beam sensor
reads the alignment pattern and adjusts the printer
automatically. Make sure you don’t open the top cover or
turn off the printer during this process.
9. When the uni-directional alignment is finished, press the
button until you see
BI-D 2-COLOR. Then press the Menu
button again to start the bi-directional black alignment
process, which is also completely automatic and takes about
7 minutes.
10. When the bi-directional black alignment is finished, press
the button until you see
BI-D ALL. Then press the Menu
button again to start the alignment process. Again, this
process is completely automatic and takes about 7 minutes.
11. When done, press the
Pause button to exit the head
alignment mode.
If you want to verify or fine-tune the automatic alignment
process, you can perform a manual head alignment. See your
electronic Reference Guide for instructions.
Replacing the Paper Cutter Blade
If you notice that your paper isn’t being cut cleanly, the cutter
blade may need to be replaced. If you use the blade to cut
heavy stock, you will damage the blade and need to replace it.
See the Printer Guide for a list of media that do not work with
the cutter.
