An effective way to clean a printhead is to remove it from the printer, extract the ink cartridges, and soak the printhead in a solution of purified water and ammonia. This four-hour process requires a plastic baggie, water, a stove or microwave, ammonia, a plastic bin, paper towels, a bath towel and latex gloves.Continue Reading
Open the printer, and remove the printer head according to the manufacturer's instructions. Put on latex gloves, disengage the ink cartridges, and seal them in a plastic baggie. Prop them upright in a safe place.
Heat several cups of purified water until the water is very hot, but not boiling. Add an equal amount of ammonia. Line a plastic bin with two paper towels, and pour in enough ammonia solution to cover the paper towels by 1/2 inch.
Set the printhead on the paper towels. Wait five minutes, then move it to a different position on the towels. Monitor the printhead carefully, and move it once every 10 minutes. Most printheads need to soak for about three hours.
Soak the printhead until it stops leaching ink into the ammonia solution. Remove it, pat it dry, and let it sit on a towel for 30 minutes. When it is completely dry, reattach the ink cartridges, and reinsert the components into the printer.
