Clean the ink cartridges

Use this feature when there is streaking, white lines through any of the lines of color or
when a color is muddy. Do not clean ink cartridges unnecessarily, as this wastes ink
and shortens the life of the ink nozzles.

1.
Load letter, A4, or legal unused plain white paper into the input tray.
2. Press Setup.
3. Select Tools, and then select Clean Cartridge.

The device prints a page that you can recycle or discard.
If copy or print quality still seems poor after you clean the ink cartridges, try
cleaning the ink cartridge contacts before replacing the affected ink cartridge.
