Owners of HP printers will occasionally have to deal with clogged ink cartridges, especially if they are light users who may leave their printers idle for long periods of time. Because the ink found in HP inkjet cartridges has a tendency to dry out after long periods of not being used, it is a good idea for HP printer owners to know how to unclog cartridges — the money they save from not wasting ink is more than worth the investment in time.
1. Put on a pair of rubber gloves and remove the clogged inkjet cartridges from your printer. Since the removal method will vary from printer to printer, check your printer’s owner’s manual if you are unclear on how to remove the clogged cartridges.
2. Place the clogged cartridges on top of an absorbent paper towel. This will prevent any dripping ink from coming into contact with the surface upon which the towel was placed.
3. Combine equal parts hot water and rubbing alcohol in a bowl or plastic container. Use enough to make the solution about an inch deep. It will serve as your unclogging agent.
4. Place the clogged cartridges into your bowl or container with the print head down and let them sit for half an hour — this will effectively loosen any dried ink. Remove the cartridges and use a cotton swab to break up the loosened ink deposits.
5. Place the unclogged cartridges on top of a dry paper towel and allow them to air dry. Make sure the cartridges have had ample time to dry completely before putting them back into your printer.
