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: 複数のインク流路が形成されたインクジェットヘッドを備えるインクジェットプリンタにおいて、印刷時の条件にかかわらず、印刷品質の低下を抑制することが可能なインクジェットプリンタを提供する。 このインクジェットプリンタでは、インクジェットヘッド3に、インクを吐出する複数のノズル3aと複数のノズル3aが繋がる複数のインク流路3c~3fとが形成され、インクジェットヘッド3は、複数のノズル3aのそれぞれからインクを吐出させる複数の吐出エネルギー発生素子を備えている。インクジェットプリンタの制御部は、複数のインク流路3c~3fのそれぞれに流入するインクの流量であるインク流量と、インクジェットヘッド3の内部温度または外部温度とに基づいて、複数のインク流路3c~3fのそれぞれにおけるインクの温度を推定するとともに、推定結果に基づいて、複数の吐出エネルギー発生素子に印加される駆動電圧を制御する。

Abstract: In an example, a fluidic device die includes a membrane layer and a piezoelectric layer stacked on this membrane layer. An adhesive layer between the membrane layer and the piezoelectric layer is deposited to adhere the piezoelectric layer to the membrane layer. A trench is etched on a surface of the membrane layer between the piezoelectric layer and a front edge of the fluidic device die.

Abstract: A memory circuit for a print component including a plurality of I/O pads, including an analog pad, to connect to a plurality of signal paths which communicate operating signals to the print component. The memory circuit includes a controllable selector connected in line with one of the signal paths via the I/O pads, the selector controllable to disconnect the corresponding signal path to the print component, and a memory component to store memory values associated with the print component. A control circuit, in response to a sequence of operating signals received by the I/O pads representing a memory read, to operate the controllable selector to disconnect the signal path to the print component to block the memory read of the print component, and provide an analog signal to the analog pad to provide an analog electrical value at the analog pad representing stored memory values selected by the memory read.

Abstract: An integrated circuit to drive a plurality of actuators during a non-reset operating condition is disclosed. The integrated circuit includes a reset input to receive a reset signal activated for a duration. The reset signal generates a reset condition in the integrated circuit during which the non-reset operating condition is blocked. The integrated circuit also includes a monitor circuit operably coupled to the reset input to indicate if the duration of the reset signal meets or exceeds a selected duration.
