Clogged printer heads can be a real pain in the neck, but the condition can definitely be prevented. Cleaning when the printer is far from being totally damaged is a lot easier than having to figure out where it should be replaced, repaired or just cleaned.
Preventive maintenance begins by buying a cleaning cartridge and use it regularly on your printer. A typical cleaning kit usually has a tube of ammonia that you can spray on the printer head and remove the dried ink.
The main method of preventing printer heads from getting clogged is to use the printer. Don’t let the unit rot. In fact, a lot of experts are saying that it is better to print one colorful page (example: a fast print, all black text settings) a week than to run a printer cleaning cycle because doing so uses a lot less ink. In general, using the printer prevents the ink in the printer cartridges to dry up.
Keeping the printer free from dirt and debris also helps a lot in preventing the printer heads from getting clogged. However, dirt and debris should never be cleaned from the printer using a vacuum cleaner because it can cause the circuitry of the printer to get fried. When that happens, you would have a bigger problem than simply dealing with clogged printer heads.
If you need to store your printer away, it would be best to take the printer cartridge out. Also, never touch the printer head with oily or dirty hands. Doing thus will leave skin oil on the printer head and add to the possibility of it getting clogged.
