    摘要： In a method for identifying of and distinguishing between at least two different predetermined disturbance states in an inkjet print head, the method comprises providing a disturbance identification input signal; applying the disturbance identification input signal to an actuator, the actuator being part of an ejection unit of an inkjet print head; receiving a residual pressure wave output signal; and analyzing the residual pressure wave output signal. The step of analyzing comprises designing and providing a respective mathematical analysis operator for each identifiable disturbance state; executing each respective mathematical analysis operator using the received residual pressure wave output signal as an input for each respective mathematical analysis operator; comparing an output of each respective mathematical analysis operator to a respective predetermined output reference; deciding for each predetermined disturbance state whether the disturbance state is present, wherein it is decided that a corresponding disturbance state is present, if an output of a respective mathematical analysis operator corresponds to the respective predetermined output reference; and it is decided that a corresponding disturbance is not present, if an output of a respective mathematical analysis operator does not correspond to the respective predetermined output reference

    摘要： Provided is an inkjet recording apparatus capable of more efficiently managing defective nozzles. The inkjet recording apparatus includes: a recording unit having a plurality of nozzles that discharge ink; a first storage unit for storing first defective nozzle information for an initially defective nozzle that occurs due to initial failure of the record - ing unit, the initially defective nozzle being a defective nozzle, among the plurality of nozzles, which discharges ink abnormally; and a second storage unit for storing second defective nozzle information for a later-occurring defective nozzle, among defective nozzles, which is not specified as the initially defective nozzle by the first defective nozzle information.

    摘要： A mounting assembly (1) for mounting a plurality of inkjet print modules in an adjoining relationship along a longitudinal direction of the mounting assembly (1) comprises a linear guide (13, 14) extending in the longitudinal direction for supporting the plurality of modules such that the modules are movable along the linear guide (13, 14). It further comprises for each of the plurality of modules a carrier (100.1 . . . 4) for mounting an inkjet print head including an array of nozzles formed on a nozzle face, wherein the carriers (100.1 . . . 4) are supported on the linear guide (13, 14) such that they are movable along the linear guide (13, 14), wherein in a mounted configuration of the inkjet print heads their nozzle face is arranged on a first side of the linear guide (13, 14). Each carrier (100.1 . . . 4) comprises a first adjustment mechanism for adjusting a distance of the carriers 100.1 . . . 4) of two adjoining modules of the plurality of modules, the first adjustment mechanism comprising a first control member having an operating section for mechanically cooperating with a tool for adjusting the distance. Each carrier (100.1 . . . 4) further comprises a second adjustment mechanism for adjusting an angle position of the inkjet print head mounted to the carrier (100.1 . . . 4) with respect to an axis perpendicular to the longitudinal direction, the second adjustment mechanism comprising a second control member having an operating section for mechanically cooperating with a tool for adjusting the angle position. The operating sections of the control members of the first and of the second adjustment mechanism are accessible from the first side of the linear guide (13, 14).
