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. ❏ If you see any gaps as shown below, click Clean to clean the print head and follow the on-screen instructions. 6. If the nozzles do not clear after a few cleaning cycles, run a Power Cleaning Cycle, as described in the next section. 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. Caution: Don't run a cleaning cycle while thick media is loaded in the printer. 1. Print a nozzle check to make sure the print head needs cleaning, as described in the previous section. 2.

Press until you see PWR CLEANING, then press Menu . Press Menu again to start the power cleaning. 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. For effective cleaning, always run a nozzle check between cycles. 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 (see 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 letter-size Epson Ultra Premium Photo Paper Luster or Epson Premium Luster Photo Paper if you are printing with Photo Black ink. If you are printing with Matte Black ink, load letter-size Epson Ultra Premium Presentation Paper Matte or Enhanced Matte Paper. 2. Press the Menu button. 3. Press the button so you see HEAD ALIGNMENT, then press Menu . You see PAPER THKNS. 4. Press Menu again so that STD appears on the display. This is the correct thickness setting for most Epson papers, including Epson Ultra Premium Photo Paper Luster, Epson Premium Luster Photo Paper, Epson Ultra Premium Presentation Paper Matte, and Enhanced Matte Paper. 5. Press Menu to register the value, then press to display PAPER THKNS again. 6. Press to display ALIGNMENT. 7. Press Menu to display AUTO, then press Menu again. You see UNI-D (uni-directional). This is the type of alignment to start with. 8. Press Menu again to start the alignment process. It takes about 12 minutes to run the automatic unidirectional 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. 10 12/07
