Abstract
A jetting apparatus for jetting droplets of viscous medium onto a substrate and a method of improving the performance of the jetting apparatus are provided. The jetting apparatus includes a jetting outlet through which the droplets are jetted, a flow generator for producing a flow of air past the jetting outlet for removing viscous medium residue at the jetting outlet, a receptacle for receiving viscous medium residue transported by the air flow away from the jetting outlet, and a flow path for the air flow between the jetting outlet and the flow generator, via the receptacle. A flow sensor is arranged in the flow path for measuring the air flow. An air flow signal representative of the air flow is obtained, the air flow signal is evaluated for determining at least one status of the jetting apparatus, and an indication of the status is provided.
