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.

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

head.

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.
