28 Maintaining Your Printer
4. Perform another nozzle check to confirm that the print head is clean, or exit
the utility.
Note:
If you don’t see any improvement after cleaning the print head four times, turn off your
printer and wait at least six hours to let any dried ink soften. Then try printing again.
If you do not use your P400 Series often, it is a good idea to print a few pages at least
once a month to maintain good print quality.
Checking and Aligning 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.
It’s best to run the automatic alignment utility first to let the printer check and
align the print head, if necessary. If you still notice alignment problems, you can
align the print head manually.
Note:
Banding may also occur if your print head nozzles need cleaning (see page 26).
1. Load a few sheets of Epson Presentation Paper Matte (or the photo paper you
have on hand) in the sheet feeder (see page 5). It’s best to use matte or photo
paper for the most accurate alignment.
