Epson CX9400 Quick Setup Guide

Cleaning the Print Head

If print quality has declined and the nozzle check 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, and may not be able to 
clean it when a cartridge is low. You must replace the cartridge first (see page 33).

1. Load letter-size plain paper in the sheet feeder.

2. Press the 

Setup

 button.

3. Select 

Maintenance

 and press 

OK

.

4. Select 

Head Cleaning 

and press 

OK

.

5. Press x

Start

. 

Cleaning lasts around 1 minute. When it’s finished, you see a message on the 
display screen.

Caution: 
Never turn off the printer during a cleaning cycle or you may damage it.

6. Press x

Start

 to run a nozzle check and confirm that the print head is clean.

Note: 
If you don’t see any improvement after cleaning the print head three times, turn off 
your all-in-one and wait at least six hours to let any dried ink soften. Then try printing 
again.

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

Your CX9400Fax Series will let you know when an ink cartridge is low or 
expended by displaying a message on its display screen or your computer.

Note: 
You cannot print or copy when an ink cartridge is expended even if the other cartridges 
are not expended. Replace any expended cartridges before printing or copying.
