Abstract: In a device for cleaning an inkjet print head (in particular the surface with nozzle exit openings) for a franking and/or addressing machine in which the print substrates are directed along a stationary but pivotably arranged inkjet print head, the entire nozzle exit surface is cleaned in a short time and a contamination of the transport region is avoided, with a small apparatus expenditure, by a wiping device formed by a driven wiping roller that is transversally, non-positively directed along the nozzle exit surface in a cleaning operation, and that continuously, non-positively rests on an associated cleaning element. The nozzle surface is repeatedly wiped off and the wiping roller is simultaneously cleaned in a single pass. An actuator of the wiping roller can be selectively coupled with an actuator for a cleaning and sealing device that operates the cleaning element, or can be autonomous.

Abstract: A measuring arrangement and measurement method determine the play of a cartridge pivot unit of an inkjet printing system that has at least one stop for the cartridge pivot unit. The cartridge pivot unit is driven by a first motor via a gear train and is equipped with a first movement sensor to establish a movement of the cartridge pivot unit upon leaving the stop. The cartridge pivot unit moves only when the play of the gear train is overcome. The stop for the cartridge pivot unit is formed by a mobile cleaning and sealing station. A counter is provided to count pulses, the count being representative of the play of the gear train of the cartridge pivot unit counting begins with leaving the mobile stop and continues until the movement of the cartridge pivot unit upon leaving the stop again ensues in conformity with the actuation by the first motor.

Abstract: A printing mechanism, especially for a franking machine, has a print head operating by the ink jet principle and a suction mechanism for suctioning away the ink spray arising when ink drops are ejected from at least one nozzle of the print head. The suction mechanism has a suction inlet, which in at least one first operating condition of the print head, when the print head is ejecting ink drops from the at least one nozzle, is arranged directly next to the at least one nozzle, so that a substantially undisturbed suction flow can be created between the at least one nozzle and the suction inlet.

Abstract: A method and a configuration provide dynamic control of a liquid supply for a moisturizing storage device for sealing glued edges of a envelope flap of letter envelopes. Once a measured value has been measured for a sealing liquid which is stored in the tank of a moisturizing apparatus, the type of sealing liquid that is used is qualitatively analyzed on the basis of the measured value and of at least one material parameter as a comparison value. The amount of liquid stored in the moisturizing storage device is then measured by at least one further measurement to allow dynamic control of the liquid supply to the moisturizing storage device as a function of the material parameter and of at least one measured value, which is related to the liquid consumption, in the result of the at least one measurement of the amount of liquid stored in the moisturizing storage device.

Abstract: A configuration for exchanging inkjet printing modules in a franking and/or addressing machine having a shaft-shaped receptacle with a locking device for the inkjet printing modules.

In particular, easy drawing of the inkjet printing module is made possible and mechanical impairment of the mating contacts for the inkjet printing module is prevented. Devices are provided for pulling and releasing the contact of the inkjet printing module in the receptacle. These devices are coupled mechanically to one another in such a way that, when the pulling process is initiated, contact is released at the same time. A wiping apparatus is arranged in the pivoting region of the rear edge of the nozzle surface of the inkjet print head.

Abstract: The invention concerns a sealing liquid comprising water and a penetration agent for sealing of mail pieces, the use of said sealing liquid as well as sealing devices and franking machines containing such a sealing liquid.

Abstract: A device spray cleans an inkjet print head. The purpose of the device is to avoid the formation of stalagmites during spray cleaning and therefore also to improve the print quality as a result of the fact that the transport device for the print carriers or items of mail is soiled as little as possible. This is achieved by a relative movement of a baffle element in a flat space or in a plane parallel to the nozzle surface of the at least one inkjet print head in conjunction with the spray cleaning.

Abstract: A device cleans an inkjet printhead in a franking and/or addressing machine. The inkjet printhead is disposed in a stationary manner such that it can be pivoted in a printing window of a guide plate for the print carrier. A cleaning and sealing device is disposed behind the guide plate such that it can be displaced toward and away from the inkjet printhead. This improves the print quality, prolongs service life, and provides a high throughput rate. Spraying clear is possible both during the print carrier transport and in a rest position without the letter run being soiled. The cleaning and sealing device is disposed underneath the inkjet printhead to be displaced by an associated displacement device. A matched baffle piece is disposed underneath the inkjet printhead such that it can pivot and is coupled to the latter.

Abstract: A device for positioning an ink jet print head and a cleaning and sealing device may be used in a postage meter and/or addressing machine for print media guided along a printing window in a guide plate by a transport device. In order to improve printing quality, the print head stationarily disposed behind the guide plate and the printing window is adjustable out of a printing position to be set in a defined way, into a cleaning and/or a sealing position and back again, and a cleaning and sealing device adapted to the print head can be coupled to the print head in a positionally accurate and functionally appropriate manner. The print head is pivotably secured and the cleaning and sealing device is disposed behind the guide plate, but linearly adjustably toward and away from the print head. A common gear for adjustment of the print head and the cleaning and sealing device is driven by a motor running in only one direction of rotation.

Abstract: An assembly for cleaning an ink jet print head which is stationary in a postage meter and/or addressing machine behind a guide plate for imprintable media in a print window. The ink jet print head is pivotable between a printing position and a cleaning and/or sealing position. A cleaning and sealing device is also disposed behind the guide plate and it is selectively movable towards the ink jet print head for cleaning and/or sealing. The cleaning and sealing device includes a sealing cap adapted to the front side of the ink jet print head, along with a transversely sweeping wiper lip and a vacuuming device. The sealing cap defines a suction region for the wiper lip, and the ink jet print head in its housing has a compartment with a replaceable absorbent filling. The wiper lip is not only stripped along the filling but also vacuumed via the suction region. The suction region is also used to vacuum the filling. This prevents soiling of the nozzle face from residual ink on the wiper lip.

Abstract: The ink jet print head includes a plurality of modules in a stacked construction or a single module. The modules are disposed in a housing. The nozzle faces of the modules protrude into associated slits of a base plate of the housing, and the modules are electrically connected to a bus adapter. The modules are pressed, by means of a spring element and a common adapter for their ink connection stubs, against an end face of the slits and against the base plate. The assembly is self-adjusting, and its accuracy depends only on the dimensional accuracy of the base plate, the spring element, and a side edge of the modules which is in effect a reference edge.
