Description

If you're experiencing poor print quality (streaked / banded prints, incorrect colors, blank pages, etc.), print a nozzle check pattern to see if any print head nozzles are clogged.

Solution

Print a nozzle check pattern to determine whether the ink ejects properly from the print head nozzle.

 If the remaining ink level is low, the nozzle check pattern will not be printed correctly. Replace the ink cartridge(s) whose ink is low.

You will need a sheet of A4 or Letter-sized plain paper.

  1. Make sure that the printer is powered on.

  2. Load a sheet of A4 or Letter-sized plain paper in the cassette.

  3. Press the OK button.

  4. Select Maintenance.

  5. Select Nozzle Check.

    Figure: LCD

    The confirmation screen will appear.

  6. Select Yes.

  7. Press the OK button.

    The nozzle check pattern will be printed and two pattern confirmation screens will appear on the LCD.

  8. Select Next.

  9. Examine the nozzle check pattern.
