My HP K5400 printer is a headache.
In the past, there was some sort of toolbox that let me "clean" the printheads.
But I can no longer find this printer utility.
I've downlaoded & installed OJProK5X00_Full_8_3.exe as well as OJProK5X00_Enterprise_Toolbox_7.exe but neither of thee seem to contain the printer utility which will cause the print heads to be exercixed.
What am I missing?

- Carefully remove any ink from the contact pads on the printhead using a dry, soft, lint-free cloth that will not come apart or leave fibers behind.CAUTION: Only wipe the contact pads. Wiping the nozzles (located on the underside of the printhead) can cause severe damage to the printhead.
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.Figure 3: Removing ink from contact padsCAUTION: Touching the nozzles can cause permanent nozzle damage. Also, ink can permanently mark clothing.
- After cleaning, place the printhead on a sheet of paper or paper towel. Make sure the nozzles are not in contact with the paper.
