How Do I Clean Clogged Inkjets on My HP 1210 Printer?

1. Open the front door of the printer, located below the scanner lid, by swinging it down. The print cartridges will move to a position where they can be accessed.
2. Unplug the printer to prevent the cartridge dock from moving away from the center of the printer.
3. Press an ink cartridge down until you feel a 'click,' then pull it out of the dock.
4. Dip a cotton swab in distilled water and use it to clean any built-up ink from the metal contacts on the ink cartridge and from the area around the ink nozzle. Avoid touching the nozzle itself, which is located in the center of the bottom of the cartridge. Discard the cotton swab if it becomes dirty, and use another to continue cleaning. Keep cleaning until the ink cartridge is no longer dirty, then set the ink cartridge aside.
5. Remove the second ink cartridge and repeat the cleaning process. Set both cartridges aside until they are completely dry.
6. Replace an ink cartridge by holding it slightly below the dock, then pushing it up and in until it snaps into place. Do the same with the second cartridge. The black cartridge is inserted into the right slot on the dock, while the color cartridge is inserted into the left slot.
7. Close the front door of the printer, plug the printer back in, and turn it on.
