Abstract:
A method of ink jet printing wherein liquid ink is supplied to a plurality of nozzles via a common ink supply passage, and actuators associated with the nozzles are controlled to cause ink droplets to be expelled from the nozzles in accordance with image information to be printed, characterized by the steps of detecting a situation where a number of the nozzles which are connected to the common ink supply passage and are presently active but stop printing within a given time interval is larger than a given maximum number; if that situation is detected, activating at least one actuator associated with one of the nozzles that stop printing with sub-threshold agitation pulses which cause an agitation of a meniscus in the nozzle without a droplet being expelled.
