INK JET DEVICE FOR PRODUCING A BIOLOGICAL ASSY SUBSTRATE BY RELEASING A PLURALITY OF SUBSTANCES ONTO THE SUBSTRATE, AND METHOD FOR MONITORING THE INK JET DEVICE

摘要

The invention provides an ink jet device for producing a biological assay substrate by releasing a plurality of substances onto the substrate, the device comprising at least a print head comprising a nozzle, the device comprising at least a transducer provided to eject a droplet out of the nozzle, wherein a detection means is assigned to the Ink jet device such that the state of the print head can be monitored by means of the detection of the behaviour of the transducer.
