ABSTRACT:
A pilot nozzle is provided for a multi-jet printing head. The pilot nozzle is continuously monitored to detect changes in phase due to changes in ink temperature, viscosity, pressure or other reason. Should a change occur requiring that the pilot nozzle be operated on a different clock phase, this change is made to all of the nozzles, without interrupting printing. The pilot nozzle is not used for printing, but is continuously monitored for the sole purpose of detecting phase changes.
