A sticky-layer-cleaner for removing residues adhered to a sticky flat layer includes a receptacle for a cleaning-liquid and a cleaning-roll in contact with the sticky flat layer, wherein the cleaning-roll includes an elongated carpet fabric which is helically folded around the cleaning-roll and a pile of which includes yarn tufts in loop and/or cut configuration, and the cleaning-roll further includes a helical channel along the length of the folded carpet fabric for draining the cleaning-liquid from the cleaning-roll and/or for wetting the cleaning-roll with the cleaning-liquid.

A sheet stacking device includes a stacker, a detector, a blower, and a moving device. A sheet is stacked on the stacker. The detector detects a stacking amount of the sheet on the stacker. The blower blows air to the sheet stacked on the stacker. The moving device moves the blower with respect to the stacker based on the stacking amount of the sheet detected by the detector.

A vacuum roller system and a method of operating the vacuum roller system can include a group of vacuum rollers operable to move a sheet of media through a dryer. The vacuum rollers do not require a vacuum to be drawn between the vacuum rollers. Each vacuum roller can include a plenum operable to direct the vacuum to a top portion of the vacuum roller to drive the sheet of media from one roller to the next roller. The plenum can engage vacuum holes in a rotating vacuum roller when the vacuum holes in the vacuum roller are aligned with the plenum.

An inkjet printing system may include an inkjet printing device, a print media finishing device, and a conditioner selectively coupled within a housing of the print media finishing device and in alignment with a print media exit of the inkjet printing device where the conditioner includes a number of heated pressure rollers to condition the print media prior to introduction into the print media finishing device.

A sheet stacking device includes a stacker, a detector, a blower, and a moving device. A sheet is stacked on the stacker. The detector detects a stacking amount of the sheet on the stacker. The blower blows air to the sheet stacked on the stacker. The moving device moves the blower with respect to the stacker based on the stacking amount of the sheet detected by the detector.

A thermosetting unit, in particular for a textile printer, includes a pair of stationary supports, a thermosetting roller extending between said stationary supports and rotatably carried by said stationary supports around a longitudinal axis thereof, a stationary infrared lamp extending inside said thermosetting roller and having opposite ends supported by said stationary supports, and a temperature-uniforming device housed inside the thermosetting roller.

An intermediate unit includes a transportation path along which a medium, on which printing has been performed by a printing unit that performs printing on the medium by using liquid, is transported to a post processing unit that performs post processing on the medium. The transportation path is provided with a drying unit that accelerates the drying of the medium. The drying unit is driven according to the printing data.

Certain examples described herein relate to transporting sheets of print media. In one example, a media transport apparatus has a plurality of media transport sections including a first media transport section and a second media transport section offset from the first media transport section in a media transport direction. The media transport apparatus has a holding section arranged to receive a sheet of print media from the first media transport section. The holding section is moveable to deposit the sheet of print media upon the second media transport section.

To form a web conveying path that bends and conveys a web, a web conveying device has: a plurality of foil supporting members that are disposed at prescribed intervals in a conveying direction of the web and that support a surface of the web that is being conveyed; a foil extending member stretched between the foil supporting members, which pulls an end of the web downstream in the conveying direction of the web such that the web extends from a starting point to an end point of the web conveying path that is formed by the foil supporting members; and a moving mechanism that moves the foil extending member from the starting point to the end point of the web conveying path.

There is provided an intermediate unit including a transportation path along which a medium, on which printing has been performed by a printing unit that performs printing on the medium by using liquid, is transported to a post processing unit that performs post processing on the medium. The transportation path includes first and second inversion paths in which the medium is inverted upside down, respectively, the second inversion path being provided with a decurling unit that corrects curl of the medium, the first inversion path being not provided with the decurling unit, the first and second inversion paths being selectively used to invert the medium upside down according to printing data for the medium.
