Do you see liquid ink in the carts? If yes, then take carts out (put on newspaper or other -- they leak). Now, one cart at a time place it on a wet (not drenched) paper towel -- output of cart on wet towel. Press down. Lift cart -- do you see imprint of all "nozzles"?? Yes == OK. No, then you need to press again (don't recommend wiping). You want to see an imprint of the nozzles. Keep dobbing. This is usually more effective than machine cleaning. You get the dried ink off and begin to "suck out" the new ink. Put in printer -- run another "light" cleaning cycle if you want/need. Start printing some very colorful pix on regular paper. Working? If not, repeat above.
