2. Remove and cap all the ink carts so they won't leak or dry.
3. Unlock the carriage lever and then lift out the printhead.
4. At your laundry room sink, use medium hot water and flush all of the ink out from the filter screens. Turn the head over and focus the water stream directly on the nozzles. Now turn the head over out of the way of the water and examine each of the filter screens. They should be wet with colored ink. Rinsh this out and turn it back over and focus the stream on each set of nozzles. Continue this until you see no more colored ink coming out.
5. Use an Air compressor to BLOW all water out of all parts of the head. You may have to use a HAIR Dryer at low heat and High air flow to dry the head. You may have to let it set over night to totally dry.
6. Check the ink flow of each ink cart. Use a 1/4 folded paper towel and blot the ink cart on the towel. You should immediately get a good wet spot of that ink. If not, Use your mouth to blow air into the top rear exit port and you should see 1 or 2 drops of ink fall onto the paper towel. If you don't get this your ink cart is internally drying up and needs to be replaced.
7. Clean the contacts on the back of the head with ISOPROpyl Alcohol, and also clean the contacts inside the carriage.
8. Install the head and the ink carts and do a "Cleaning Cycle" from inside the PC printer maintenance window.
9. Print only a "Nozzle Check Print" to prove you have returned good ink into the head.
