Abstract
A method for detecting clogged or otherwise anomalous nozzles in an ink jet printing device having a printer head containing at least one nozzle configured to eject droplets of ink, the method including sending an instruction to the printer head to eject droplets of ink, generating an output signal from a detecting means configured to detect a passage of droplets past the detecting means and applying an algorithm to the output signal which is configurable to check a correct functioning of the nozzles.
