ABSTRACT:
The invention relates to a method for monitoring the viscosity of ink in a continuous jet ink jet printer, which method comprises causing at least part of the ink to flow through a restricted orifice into a vessel and measuring the time taken to fill the vessel between a lower level limit and an upper level limit and allowing ink to escape from the vessel to reduce the level to below the lower level limit, characterized in that ink is automatically removed from the vessel by a syphon when the ink has reached the upper level limit.
