Clean the Print Head Nozzles

If print quality has declined and the nozzle check pattern indicates clogged nozzles, you can clean the print head.

Note:
You cannot clean the print head if an ink cartridge is expended, and may not be able to clean it when a cartridge is low. You must replace the cartridge first.

You can clean the print head using the Epson Stylus NX400 Series control panel or your software.

Using the Control Panel

1.	Load a few sheets of plain paper in the sheet feeder.

2.	Press Setup.

3.	Select Maintenance and press OK.

4.	Select Head Cleaning and press OK.

5.	Press  Start.

Follow any instructions on the LCD display screen during cleaning, which lasts around 1 minute. When it’s finished, you see a message on the screen.

Caution:
Never turn off the Epson Stylus NX400 Series during a cleaning cycle or you may damage it.

6.	Run a nozzle check to confirm that the print head is clean.

You may need to clean the print head up to 3 times. You can also turn off the Epson Stylus NX400 Series and wait at least 6 hours. Then try printing again.
