  • Patent number: 10688789
    Abstract: An inkjet printing device is provided. The second liquid storage tank is connected to a second buffer tank and the second buffer tank is pressurized so that the pressure at one side of the spray head near the second liquid storage tank is greater than the pressure at another side near the first liquid storage tank. As a result, the chemical solution in the spray head flows back into the first liquid storage tank or the liquid supply tank. Consequently, there is no residual chemical solution at the spray head so that the problem of the blocked spray head is not induced. Furthermore, by pressurizing the second buffer tank, the boiling point of the chemical solution can be reduced. The volatilization and solidification of the chemical solvent is reduced even further. Therefore, the problem of the blocked spray head is further mitigated. The quality of the chemical solution is ensured for a long time.

  • Patent number: 10625499
    Abstract: A method for detecting and compensating for defective print heads in an inkjet printing machine uses a computer to analyze printing nozzle test charts and/or area coverage elements to obtain characteristic values of individual printing nozzles in a print head, to calculate the failure probabilities of these printing nozzles on the basis of thresholds, and to compensate for a printing nozzle that exceeds a specified failure probability. The computer uses the individual failure probabilities of the individual printing nozzles in a print head to calculate the failure probability of the print head and initiates compensation measures as a function of the calculation. The thresholds correspond to a multi-dimensional characteristic value threshold based on which the computer calculates the failure probability of a printing nozzle by using an algorithm including kernel density estimation through a multidimensional distribution function.

    Abstract: A processor of a print device performs empty processing in a case where it has determined that it has received, from a remaining ink amount detector, a first signal that indicates that a remaining amount of an ink is not greater than a first prescribed amount. The processor also performs the empty processing in a case where it has not determined that it has received the first signal, but has determined that it has received a second signal. In the empty processing, the processor performs soak cleaning of a nozzle face and stores an empty soak standby flag in an EEPROM. The empty soak standby flag is a flag that prohibits the performing of a printing operation. Therefore, the print device is able to reduce the possibility that a decline in print quality will occur.

  • Patent number: 10576735
    Abstract: A non-contact printer controls the sensitivity of sensors provided upstream of a print head, to detect the approach of an object. In a calibration operation to set the sensitivity level of the sensors before a printing operation, the printer displays instructions to guide the operator and adjusts the sensor sensitivity to find detection threshold levels for a background (object absent) condition and when the object is present. The calibration results may be stored in association with data identifying the conveyor and the type of object used in the calibration operation. If the same conveyor and/or object type is used again in a later printing operation, the sensitivity level of the sensors can be set using the stored calibration results so that a further calibration operation is not necessary.

  • Patent number: 10562295
    Abstract: A fluid dispenser calibration system includes a fluid dispenser having a plurality of nozzles, a balance having a balance surface, and a mask positioned between the fluid dispenser and the balance surface. A nozzle pitch is a distance between two adjacent nozzles. The balance measures mass of fluid dispensed from a single nozzle and measures a change in mass on the balance surface. The balance surface has a linear dimension that is greater than the nozzle pitch. The mask includes an aperture and a catch region. The aperture allows fluid dispensed from the single nozzle to impact the balance surface. The catch region catches fluid dispensed from remaining nozzles in the plurality of nozzles.

  • Patent number: 10549545
    Abstract: A method for detecting and compensating defective printing nozzles in an inkjet printing machine includes periodically printing at least one printing nozzle test chart having horizontal rows of equidistant vertical lines underneath one another, with only nozzles contributing to the test chart in every row corresponding to horizontal rows, and printing an area coverage element geometrically associated with the test chart. Both elements are recorded by an image sensor and evaluated by a computer. The computer identifies print defects by evaluating the area coverage element and allocates the defects to defective nozzles. The computer evaluates the test chart based on thresholds to detect defective nozzles and compensate detected defective nozzles. The computer compares the detected defective nozzles from the area coverage element and the test chart to identify detected defective nozzles causing defects in only one element and calculates the thresholds based thereon to minimize the detected defective nozzles.
