Adjust Print Quality : Align the Print Head

Align the Print Head
If your printouts become grainy or blurry, or you see dark or light bands across them, you may need to align the print head.
Note:
Banding may also occur if your print head nozzles need cleaning.
1.
Load a few sheets of Epson Presentation Paper Matte (or the photo paper you have on hand) in the sheet feeder. It’s best to use matte or photo paper for the most accurate alignment.
2.
Windows: Right-click the  icon in the bottom right corner of your screen (the taskbar) and select Print Head Alignment.
Macintosh: Open the Applications folder, open the Epson Software folder, and open the EPSON Printer Utility 4. If you have more than one printer, click Printer List and select your product. Then select Print Head Alignment.
3.
Click Next and follow the on-screen instructions to print the first alignment sheet.
4.
Note:
If no patterns are aligned, choose the closest one and click Realignment. Then print another alignment sheet and check it.
