6. Click the Nozzle Check icon, then click Next. See the

next section for instructions on examining the nozzle check

pattern.

7. If your print quality has not improved, repeat the steps

above. If you don't notice any improvement after doing this

two or three times, check the print quality solutions in the

User's Guide.

Examining the Nozzle Check Pattern

Examine the nozzle check pattern you print. It should look

something like this, with the lower pattern colored cyan,

magenta, and yellow:

Each staggered horizontal and straight vertical line should be

complete, with no gaps in the dot pattern. If your printout

looks okay, you're done. If any dots are missing, as illustrated

below, clean the print heads again.

Aligning the Print Heads

If your printouts contain misaligned vertical lines, you may

need to align the print heads. You can align the print heads in

either of the following ways:

With the Print Head Alignment utility in your printer

software (when the printer is connected to a local port only)

Using the printer's control panel buttons

Using the Print Head Alignment Utility

Follow these steps to run the utility (Windows or Macintosh):

1. Make sure the printer is turned on and paper is loaded.

Caution:

Load paper that's at least 8.27 inches (210 mm) wide. This

prevents ink from spraying inside the printer and smudging your

printouts. For the best results, load EPSON ink jet paper to check

your alignment.

2. Access the printer settings dialog box.

4. Click the Print Head Alignment icon.

and select the correct alignment.

Using the Control Panel to Align the Print

Heads

Follow these steps to align the print heads:

1. Make sure the printer is turned off and paper is loaded.

Then open the printer cover.

Caution:

Load paper that's at least 8.27 inches (210 mm) wide. This

prevents ink from spraying inside the printer and smudging your

printouts. For the best results, load EPSON ink jet paper to check

your alignment.

2. Hold down the

load/eject button and the

button and turn on the printer. Then release the buttons.

After a moment, the printer prints an instruction sheet

telling you how to select a language for the alignment

instructions.

3. Press the correct control panel buttons as instructed to select

a language. The printer prints instructions for aligning the

print heads.

4. Follow the instructions on the sheet to align the print heads.

When you're finished, turn off the printer to exit the

alignment mode.

Using Special Media

When you print on special media, you need to be careful

about choosing the correct Media Type and Paper Size

settings in your printer software. The table on the following

page lists the available EPSON media and the corresponding
