Abstract
In a method for determining a maintenance performance of a maintenance unit of an inkjet printing system, the inkjet system comprises an inkjet print head having an orifice surface, the orifice surface comprising an orifice, which orifice is in fluid communication with an ink chamber. The method comprises operating the maintenance unit to perform a maintenance operation on the orifice surface of the inkjet print head and detecting the presence of a wiper element or amount of ink over the orifice by detecting a pressure wave in the ink chamber and analyzing the detected pressure wave to determine the maintenance performance of the maintenance unit.
