Abstract
The present invention relates to an inkjet print head device for continuous inkjet printing, comprising a transducer; a charge electrode; a deflection plate; a gutter; and a holster; provided that the holster is receiving at least the aforementioned components, wherein the holster comprises an opening for a dedicated outlet for the ink in a printing mode, and wherein the holster further comprises an ink leakage detection area. Further the invention relates to a method and a system for detecting ink leakage in a print head. [ok]
Claims13
A system for detecting ink leakage in a print head for continuous inkjet printing, comprising an inkjet print head device, a sensor controller and a main controller for monitoring the signals from the sensor, the inkjet print head device comprising a transducer, a charge electrode, a deflection plate, a gutter, and a holster, provided that the holster is receiving at least the aforementioned components of the inkjet print head device,
- wherein the holster comprises an opening for a dedicated outlet for the ink a printing mode and further comprises an ink leakage detection area, the ink leakage detection area comprising a non-conductive substrate and conductive circuit provided thereon,
- wherein the sensor controller is operatively connected to the ink leakage detection area,
- wherein the ink leakage detection area is configured to send to the sensor controller an ink leak signal, a holster mounted signal and a signal referring about a wiring connection.
A method for detecting ink leakage providing
- an ink leak signal from a leakage detection area of a holster of a print head device, the ink leakage detection area comprising a non-conductive substrate and conductive circuit provided thereon;
- a holster mounted signal;
- a signal referring about a wiring connection;
- whereas the three signals are sent from a leakage detectionarea to a sensor controller and further to a control cabinet.
