When the Ink Nozzles Are Clogged
Prolonged exposure to air may cause ink crust to form
on the ink nozzles of the print cartridge. You can try to
clear the crusted ink from the print cartridge, as follows:
Note: Ink may stain your hands or clothing.
1. Hold the print cartridge by its green top. Using
a water-damp cloth, gently and slowly wipe the
dried ink off the print cartridge nozzles into a
trash container. Repeat this step, using a clean
portion of the damp cloth to wipe residual ink
off the nozzles.
2. Install the print cartridge in the printer and load
paper in the paper tray.
3. Turn off the printer.
4. While pressing the Change Cartridge button ( ),
press the Power button ( ) to activate the
cleaning process. A page will then be printed.
If the print quality is unsatisfactory, the print
cartridge may be out of ink. In this case, use a
new print cartridge.
