    Abstract: A printing unit prints to a pre-folded substrate web. An intake unit is at an intake of a transport arrangement. A synchronization sensor is at the transport arrangement between an infeed roller and the printing unit. The synchronization sensor emits a synchronization signal when a fold of the web is present at the synchronization sensor for synchronization of a printing operation with feed of the web. A path between the synchronization sensor and a freely accessible point of the intake unit is designed such that a fold is present at the synchronization sensor when the printing substrate web has a fold at the accessible point. A relative humidity sensor is at the printing unit. A relative humidity measured by the sensor is compared with a relative humidity of an input stack. Given a deviation a length change of the web between the synchronization sensor and the accessible point is calculated, the web being displaced by the length change at the accessible point.

  • Patent number: 8636139
    Abstract: A conveyor has drive and driven shafts mounted to undergo rotation, a transmitting member transmitting a rotational drive of the drive shaft to the driven shaft in synchronization relative one another, an elastic conveying member looped around the drive and driven shafts for conveying an object, and a guide portion arranged between the drive and driven shafts. The guide portion has rotators, receiving portions receiving respective ones of the rotators, openings communicating with through-holes of the conveying member, communication portions communicating with the openings and positioned so that each of the rotators is arranged between respective adjacent pairs of the communication portions, and connection members communicating with the openings via the communication portions. The connection members are configured for connection to a suction device for drawing air from the openings through the respective communication portions to draw by suction the conveyance object toward the conveying member.

  • Patent number: 8408539
    Abstract: A media sheet transport including a belt for supporting the media thereon. The belt is operably connected to a drive mechanism for moving the belt in a process direction past an image marking unit. The belt has a plurality of openings therein. A vacuum plenum has a surface disposed below the belt and is operably connected to a vacuum source. The vacuum plenum is adapted to applying a negative pressure to the media for holding the media to the belt. An electrostatic hold down apparatus includes a first tacking roller spaced in a cross-process direction from a second tacking roller. The first and second tacking rollers are engagable with the belt. The first tacking roller is disposed to engage the inboard edge of the media, and the second tacking roller is disposed to engage the outboard edge of the media. The first and second tacking rollers impart an electrostatic charge to the edges of the media for electrostatically securing the inboard and outboard edges of the media to the belt.

  • Patent number: 8277040
    Abstract: A printer has an exhaust path that rectifies the exhaust flow of a centrifugal fan for producing air flow through a vacuum platen. Exhaust from a centrifugal fan 30 tends to flow in the direction of rotation A of the blades due to inertia even after being discharged from the exhaust opening 39. The exhaust thus produces a curving exhaust current C. An exhaust duct 32 connected to the exhaust opening 39 of the centrifugal fan 30 therefore curves in the direction of rotation A of the blades so as to not impede the flow of the exhaust current C. As a result, turbulence inside the exhaust duct 32 is suppressed, and the exhaust current C is rectified. The exhaust from the centrifugal fan 30 can therefore flow smoothly, and a loss of exhaust flow can be suppressed. In addition, noise caused by the exhaust current C hitting the inside wall of the exhaust duct 32 can be suppressed.
