The very narrow inkjet nozzles are prone to clogging. The ink consumed cleaning them -- either during cleaning invoked by the user, or in many cases, performed automatically by the printer on a routine schedule -- can account for a significant proportion of the ink used in the machine. Inkjet printing head nozzles can be cleaned using specialized solvents; or by soaking in warm distilled water for short periods of time, for water - soluble inks.
