6.Wipe the electrical contacts on the printhead but do not touch the nozzles.

NOTE: The electrical contacts are small copper-color squares, grouped on one face of the printhead.

The nozzles are on a different face of the printhead. Ink will be visible on the nozzles.

CAUTION: Touching the nozzles can cause permanent nozzle damage. Also, ink can permanently mark clothing.

7.After cleaning, place the printhead on a sheet of paper or paper towel. Make sure the nozzles are facing up and are not in contact with the paper.
