Publication number: 20190337301Abstract: A closed supply container that is filled with air and ink is associated with a print head in a one-to-one association. During a printing process, ink is drawn from the supply container into the print head via a connecting line, such that a negative pressure in the supply container is increased. A sensor in the supply container measures the negative pressure and transmits a measurement value to a controller that switches a valve associated with the supply container so that ink is conveyed from an ink storage container into the supply container of the measurement value falls below a predetermined first lower limit value of the pressure such that the fluid pressure in the supply container increases.Type: ApplicationFiled: May 7, 2019Publication date: November 7, 2019Applicant: Océ Holding B.V.Inventor: Florian Hitzlsperger

Patent number: 10464352Abstract: A method of duplex printing on a cut sheet printer having a sheet supply system for feeding sheets to a print station in a first orientation for printing a first image on the first side of the sheet and then in a second orientation for printing a second image on a second side of the sheet includes, for each sheet: (a) estimating a likelihood P1 that, in a print process for printing the first image, the sheet will become damaged to such an extent that the damage will compromise a later print process for printing the second image; (b) comparing the likelihood P1 to a threshold T; and (c) if the likelihood P1 exceeds the threshold T, reversing the print order so that the second image is printed before the first image. The method ensures that the riskier image is printed on the duplex pass. The chances of the sheet with the simplex image then successfully passing through the duplex pass are then increased.Type: GrantFiled: September 25, 2018Date of Patent: November 5, 2019Assignee: OCÉ HOLDING B.V.Inventor: Ernest J.

Patent number: 10467512Abstract: A method of using an interface device to interface to a processing unit is disclosed. The interface device and the processing unit are part of a station of a plurality of stations in a sheet processing line. The method involves using the interface device to receive a control signal from an upstream station, and comparing a selection part of the control signal with a reference, the selection part being part of an addressing part of the control signal. If the comparison result is negative, a further control signal is determined from the control signal, which is derived from and differing from the addressing part of the control signal and the interface device outputs the further control signal to a different interface device corresponding to a processing unit of a downstream station. If the comparison result is positive, an instruction signal is sent from the interface device to the processing unit.Type: GrantFiled: September 23, 2016Date of Patent: November 5, 2019Assignee: OCE-TECHNOLOGIES B.V.Inventors: Erik J.

Patent number: 10391794Abstract: A duplex sheet printer comprising a first and second sheet quality detection device for determining a suitability of a sheet for printing. The first sheet quality detection device applies a first sheet rejection threshold to which sensed sheets are compared, while the second sheet quality detection device applies a second sheet rejection threshold different from the first. The controller designates sheets in the printing system to be sensed by one of the sheet quality detection devices in accordance with the sheet's media type or the sheet being on a simplex or duplex pass. Different rejection criteria are thus applied to the sheets without adjustment of a sheet quality detection device, resulting in high speed printing.Type: GrantFiled: August 24, 2018Date of Patent: August 27, 2019Assignee: OCÉ HOLDING B.V.Inventors: Cornelius Janssen, Leon C.
