Abstract: A system (93) monitors the break-up phase of an electrostatic deflection continuous ink jet printer to identify phase instability likely to be caused by a partial blockage of the jet-forming device (17). It ignores alternations between adjacent phase positions and brief unrepeated periods of phase disruption. Preferably it ignores phase changes caused by changes in other operational parameters of the printer, such as variations in ink pressure. Monitoring may be done in the printer (99) or in an external system (93), (95).

Abstract: A continuous inkjet printer is provided comprising an ink supply system, a droplet generator configured to receive ink from the ink supply system and to produce a jet of ink for printing, a gutter configured to receive parts of the jet that are not required for printing, a gutter line connected to the gutter and configured to return unprinted ink to the ink supply system, a suction system comprising a Venturi having a suction port configured to apply a suction force to the gutter line, and a gutter flow rate control system configured to control a rate of flow of fluid along the gutter line based on temperature.

Abstract: The current at a deflection electrode 23, 25 of an electrostatic deflection continuous inkjet printer 127 is monitored. If the current reaches a level higher than normal for a clean print head but below the current required to trigger an automatic shutdown, a warning is generated. The warning indicates that an automatic shutdown is likely to follow unless the print head is cleaned. This allows the operator to shut the printer down in a planned manner for cleaning. The warning may be provided at the printer 127 or it may be provided by an external system 121, 129 which allows personnel who are not at the printer to be alerted. The monitoring may be done by the printer or information about the deflection electrode current may be provided to an external system 121, 129 that performs the monitoring.
