Patent number: 10828915Abstract: A transporter can transports a recording medium on a transport belt through a print group with at least one print head. The transport belt has a plurality of holes via which a negative pressure may be produced to draw/hold a recording medium onto the transport belt. To avoid an air flow below the print head, a decoupler can selectively cover, seal, and/or decouple a source of the negative pressure such that no negative pressure is produced through the holes that are located below the print head and that are not covered by a recording medium.Type: GrantFiled: August 1, 2019Date of Patent: November 10, 2020Assignee: Canon Production Printing Holding B.V.Inventor: Thomas Montag

Patent number: 9535385Abstract: In a method to adjust print quality of print images in an electrophoretic digital printer with at least one print group, the print group generates charge images of the print images. The charge images are developed with a developer station into toner images using liquid developer having carrier fluid and toner. The toner images are transfer-printed onto a carrier medium in a transfer station. A first control marking is generated on the recording medium with elements of the first control marking being aligned transverse to a printing direction. A shape of the elements of the first control marking is measured to generate a first measurement signal. The first measurement signal is compared with a predetermined nominal value, and given a difference, an adjustment signal is generated via which an amount of the carrier fluid in the liquid developer is modified so that the first measurement signal approaches the predetermined nominal value.Type: GrantFiled: February 4, 2016Date of Patent: January 3, 2017Assignee: Océ Printing Systems GmbH & Co.

Patent number: 9057989Abstract: In a method or system to operate a digital printer for double-side printing to a recording medium with toner particles applied with a liquid developer, the digital printer prints first and second sides of the recording medium in succession. Electrophoretic mobility of toner particles of a first toner image on the first side is reduced after application of said first toner image and before application of the second toner image on the second side of the recording medium. The electrophoretic mobility is reduced by drying the first toner image along a drying route in an airflow generated by a blower such that carrier fluid is thus removed from the first toner image. After the application of the second toner image on the second side of the recording medium, both the first and second toner images are simultaneously fixed.Type: GrantFiled: April 17, 2013Date of Patent: June 16, 2015Assignee: Océ Printing Systems GmbHInventors: Thomas Montag, Alexander Breitenbach, Gunnar Raschke, Andrae le Coutre, Roland Bilke
