If printing is faint or affected by banding in different colors, make sure the printhead nozzles are clear by printing a test pattern to check the nozzles (Nozzle Test).


Printing the Nozzle Test.
1.  Load Paper
2.  Flick Home screen and tap Maintenance.  The Maintenance screen appears.
3.  Tap Print nozzle check pattern.  A confirmation message appears.
4.  Tap Yes.  The printer now prints a test pattern for checking the nozzles.
5.  Check the printing results.

Because CO has no color, printing is performed on top of the black pattern.  Check if the dark gray areas have lines (A) in the CO Pattern

If horizontal lines are faint or incomplete, execute printhead cleaning.

Cleaning the Printhead:
If printing is faint, cleaning the print head may improve results.

1.  Flick Home screen and tap Maintenance.  The Maintenance screen appears.
2.  Tap Print Head Cleaning

Choose one of three printhead cleaning modes (Cleaning, Deep cleaning, or System cleaning) depending on the problem to resolve.
  • Cleaning
Use this mode if printing is faint or contains foreign substances.  This method of cleaning consumes the least amount of ink.
It gales about 8 minutes.
  • Deep cleaning
Use this mode if no ink is ejected at all or if Cleaning does not solve the problem.
It takes about 8 or 9 minutes.
  • System cleaning
Use this if printing is not improved after Deep cleaning.  System cleaning consumables a very large amount of ink.  Performing this frequently consumes the ink faster.  Perform this only when needed.
It takes about 10 minutes.


Check the nozzle check pattern and select an ink group for which to perform cleaning as needed.  You can clean all printhead or select pattern 1, 2, or 3 to clean the printhead with a clogged nozzle.
