How do I clean the printheads on my printer?

A.

Press On Line. The LCD displays “OFF LINE . Press the cartirdge + key, and the cartridge station should come out. Remove the cartridge.

During printing, ink spray, paper fibers, and dust can build up on the print cartridge. These can eventually degrade the print quality. When this occurs, the print cartridge should be wiped with a wet fiberless cloth.  Wipe slowly across the long-axis with the print cartridge facing down (as shown). Do not apply excessive force, as this could scratch the nozzle area.

The cloth must be soft so that it does not scratch the print cartridge. It should be fiberless, because small cloth fibers can be left behind and block the nozzles of the print cartridge. The cloth must be moistened with liquid or it may scratch the print cartridge. Scratches on the print cartridge prevent the ink from coming out of the nozzle straight. If the ink drops do not come out of the nozzle straight, they will not land on the paper in the proper place, causing fuzzy text. De-ionized water is better than tap water, because tap water contains minerals that can leave behind deposits in the chambers. During wiping, the water cleans out the nozzles and the firing chambers. A small amount of water mixes with the ink in the chambers.

When finished, replace cartridge. If the print quality remains a problem, install a new cartridge.
