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 32).

1. Press if necessary and select

Setup

2. Select

Maintenance

, then

Head Cleaning.

3. When you see the first screen, press

, then choose the colors you want to

clean.

Tip:

Use the nozzle check pattern to determine which colors need cleaning. You can

save ink by cleaning only selected colors.

Cleaning takes a few minutes. When it’s finished, you see a message on the

LCD screen.

Caution:

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

4. Select

Nozzle Check

. Then press x 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 four times, leave the

product on 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 53.

If you do not use your product often, it is a good idea to print a few pages at least once

a month to maintain good print quality.
