Checking and Aligning the Print Head

Checking and Aligning the Print Head
If your prints look grainy or blurry, or you see
misregistration or "ghosting," you need to align the print
head. First, you need to make sure the nozzles are clean.
Running a Nozzle Check and
Auto Cleaning
You can turn on Auto Cleaning at the same time you
check the print head nozzles. The printer prints the check
pattern, reads it, and automatically runs a cleaning cycle
if necessary. First, make sure paper is loaded in the tray.

In Mac OS X, you'll find it in the Epson Printer

Click Auto and follow the instructions on the
