A method of operating a continuous inkjet printer (). The printer comprise a printhead. The printhead comprises a droplet generator () comprising a printing nozzle () for ejecting an ink jet for printing, at least one electrode () for steering the inkjet, and a gutter () having an ink receiving orifice () 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 () surrounding the orifice () for cleaning said part of the gutter surrounding the orifice.

Method of operating a printhead

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.

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.

Techniques for operating an industrial printer include causing it to report data that indicates COO parameter values based on output sensors and/or component detection module configured to measure physical phenomena related to components of the printer referred to as COO parameters. The COO parameters values, which may include waste values, are derived and displayed in a graphical user interface dynamically on a real time basis. One or more graphical user interface is generated to present a one or more active areas to select the display of the COO parameter values in numeric and or graphical form or combinations thereof.

System and method for operating an industrial printer

There is provided a charge electrode for charging ink droplets for continuous ink jet printing. The charge electrode has a generally cylindrical main body defining a generally cylindrical passage for the ink droplets, said passage extending along a travel axis that represents, in use, the position of an ink jet in ingress to the electrode and a direction of travel of the ink droplets once these have detached from the ink jet. The charge electrode comprises two distinct axially disposed regions: a first region for charging the droplets as required; and, a second region for screening the charged droplets from any electric fields which could undesirably affect the trajectory of the ink jet and/or the droplets. The second region may fully surround at least a portion of the travel axis. The invention therefore provides improved screening for the ink jet and/or the droplets. This may in turn enable better control of the charge applied to the charged droplets, and/or of their travel trajectory.

Charge electrode

A tamper-evident, single use, ring assembly, is assembled from first and second interengaging broken rings (). The first broken ring () is of a first material and the second broken ring () is of a second material. A break in the ring of the first material is offset circumferentially from a break in the ring of the second material. The assembly of the rings forms a closed ring assembly which can be cut through in the region of the break in the ring of the first material to open the ring assembly. At least one of the rings () of the ring assembly is resiliently stressed in its assembled state such that, upon cutting through of the ring assembly, the confronting ends of the assembly move apart.

A cartridge for storing and dispensing liquid for use with an inkjet printer includes a reservoir for storage of the liquid and an outlet for dispensing the liquid. The reservoir has a reinforcing structure and maintains a predetermined separation. The reinforcing structure separates an internal space of the reservoir into a first and second chamber. The reinforcing structure provides a fluid communication path between the chambers. The reinforcing structure has first and second portions of wall that partially defining the first and second chambers. The reinforcing structure has a wall partially defining the fluid communication path. The first and second portions of the wall have an arcuate profile. The first and second chambers have respective first and second widths. The fluid communication path has a third width which is less than the first or second widths.
