Abstract: A binary array ink jet printhead assembly includes a cavity for containing ink, nozzle orifices in fluid communication with the cavity for passing the ink from the cavity to form droplets, the nozzle orifices extending along a length of the cavity, and an electrode assembly. The electrode assembly includes a front face configured to be disposed generally parallel to a plurality of droplet paths of droplets from the nozzle orifices. A plurality of charge electrodes are disposed on the front face, each charge electrode corresponding to a droplet path and disposed parallel to the droplet path. Circuitry is disposed on the electrode assembly, wherein each electrode is electrically connected to the circuitry. The circuitry is further in electrical connection to a connector for connecting the electrode assembly to a controller for the printhead.

Abstract: A continuous ink jet printer including an ink tank for holding ink, an ink nozzle in fluid communication with the ink tank for ejecting ink droplets, and a gutter for receiving, through an ink-receiving inlet thereof, ink droplets which are not used for printing. A gutter flow path starts at the ink-receiving inlet for ink that has entered the gutter through the ink-receiving inlet, and provides fluid communication to the ink tank. A return line is in fluid communication with the print head for conveying air to enter the gutter flow path. A makeup tank is in vapor communication with the ink tank to allow air to be conveyed from the ink tank to the makeup tank. A condenser is in fluid communication with the makeup tank and the return line for condensing solvent.

Abstract: A method of operating a continuous inkjet printer (1). The printer comprise a printhead. The printhead comprises a droplet generator (16) comprising a printing nozzle (17) for ejecting an ink jet for printing, at least one electrode (22, 23) for steering the inkjet, and a gutter (18) having an ink receiving orifice (24) for receiving parts of the ink jet which are not used for printing. The method comprises performing a cleaning operation. Said cleaning operation comprises: ejecting a solvent jet from the printing nozzle towards the gutter; and causing at least a portion of the solvent jet to contact at least a part of the gutter (18) surrounding the orifice (24) for cleaning said part of the gutter surrounding the orifice.

Abstract: A system having a plurality of marking and/or coding devices and a computing system coupled to the devices and having processor configured to: receive sensor data associated with each device; and store printer metadata and batch job metadata in a backup file for each device. The processor is configured to classify a fault condition of a respective one device based on one or more of received sensor data, device self-test data, current operational data and historical device condition data. The processor is configured to determine autonomously a repair process recommendation in response to the classified fault condition and based on an estimated time to repair (ETR) the device using a self-repair recovery process relative to a line recovery time (LRT) threshold. The processor is configured to recommend as the repair process recommendation the self-repair recovery process in response to the ETR being less than or equal to the LRT threshold.
