Print Head Deep Cleaning

If print quality does not improve by standard print head cleaning, try print head deep cleaning,
which is a more powerful process. Print head deep cleaning consumes ink, so perform this
procedure only when necessary.
1
Ensure that the printer is on.
2
Start Print Head Deep Cleaning.
Important The process takes one or two minutes to complete, so simply wait until the
Power Power lamp stops flashing.

After print head deep cleaning finishes, print the nozzle check pattern to verify
Note
that the print head nozzles are clean.
See "Printing the Nozzle Check Pattern" on page 29.
If the print head is still not clean after the second deep cleaning, replace the ink
tank. See "Replacing an Ink Tank" on page 34.
If ink tank replacement does not resolve the problem, the print head may be
worn out. Contact the Customer Care Center.
