3.Click the Nozzle Check icon.
4.Click Auto and follow the instructions on the screen.
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 printer’s control panel if the normal cleaning process is not sufficient to clear the nozzles. However, the power cycle uses a larger 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. If the waste ink tank is nearly full, you may need to replace it. After running the cleaning cycle, you can reinsert the old cartridge.
1.Print a nozzle check to make sure the print head needs cleaning, as described above.
2.Make sure no paper is loaded and the red B ink light on the printer’s LCD panel is not on or flashing.
3.Press the Menu 
button.
4.Press the 
button until you see MAINTENANCE, then press Menu 
.
5.Press the 
button until you see PWR CLEANING, then press Menu 
to start the cleaning process.
6.Follow the instructions on the LCD panel to raise or lower the ink levers.
7.When cleaning is finished and the 
Pause light stops flashing, print the nozzle check again to confirm that the head is clean.
You may need to run the cleaning cycle several times to get a clean nozzle check pattern. For effective cleaning, always run a nozzle check between cycles.
If the lines in the pattern are still missing dots after several cleaning cycles, turn the printer off and leave it overnight, then clean the print head again the following morning. 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 8). 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 paper. Epson Enhanced Matte paper is recommended.
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
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.
