Epson NX400 Guida Utente

Cleaning the Print Head

If print quality has declined and the nozzle check pattern indicates clogged 
nozzles, you can clean the print head. Print head cleaning uses ink, so clean it only 
if necessary.

Note: 
You cannot clean the print head if an ink cartridge is expended or low. You must replace 
the cartridge first

 

(see page 33).

1. Load letter-size paper in the sheet feeder 

(see page 5).

2. Press

5. Press x

Start

.

Cleaning takes approximately one minute. When it’s finished, you see a 
message on the display screen.

Never turn off the NX400 Series during head cleaning or you may damage it.

6. Press x

Start

 to run a nozzle check (as described on page 30) to verify that 

the print head is clean. 

7. If there are still gaps or lines, or the test patterns are faint, run another 

cleaning cycle and check the nozzles again.

Note: 
If you don’t see any improvement after cleaning the print head four times, turn off your 
NX400 Series and wait at least six hours to let any dried ink soften. Then try cleaning 
the print head again. If quality does not improve, one of the ink cartridges may need to 
be replaced. If that doesn’t help, contact Epson as described on page 40.

If you do not use your NX400 Series often, it is a good idea to print a few pages at least 
once a month to maintain good print quality.
