nevermind, found it from Randya....
Use a non-shedding clean room cloth.
Fold in half and wet with cleaning solution from one of the cleaning cartridges. (You should gut one of your cleaning cartridges and store the liquid in a poly bottle).
Place the wet cleaning cloth on the cap (s)
Raise the head (or lower the capping station.
Move the head over the capping station and lower the head (or release the capping station).
Rewet with cleaning solution every 15 minutes.
After two cycles run a strong clean and nozzle check.
Rinse, lather, repeat until all nozzles are clear. (Mild plugs will free in just a few cycles, hard core plugs could take hours.)
The whole idea here is to get cleaning solution up against the plug in the nozzle (without damaging the nozzle) to soften it up and allow the pump to pull it out.
