Abstract: There is disclosed apparatus for wetting a roller of a printing system comprising an applicator unit comprising a liquid agent chamber. Upper and lower walls extend from the liquid agent chamber to define a slit therebetween. The upper wall extends beyond a lip of the lower wall to a transfer lip. A flow restrictor is received in the slit to prevent flow of liquid agent to a respective portion of the transfer lip, thereby defining a restricted portion of the slit and an adjacent unrestricted portion of the slit. The flow restrictor fits in the restricted portion with a clearance that permits liquid agent flow at a reduced velocity relative flow through the unrestricted portion, such that liquid agent along the restricted portion is discharged from the lower wall. A method of installing a flow restrictor is also disclosed.

Abstract: In an example of the disclosure, a blanket servicing system includes a rotatably mounted endless cleaning surface and a scraper. The endless cleaning surface is to have a first engagement with a blanket to obtain a layer of thermoplastic print agent from the blanket. The endless cleaning surface is to have a second engagement with the blanket to receive residue from the blanket onto the layer of thermoplastic print agent. The scraper is to scrape the endless cleaning surface to transfer the residue from the endless cleaning surface to a collection element.

Abstract: In an example, a print apparatus comprises an intermediate transfer member to receive thermoplastic print agent from a photoconductive surface, a rotatably mounted endless cleaning surface to receive a layer of thermoplastic print agent from the intermediate transfer member and a heater, to heat the endless cleaning surface. The endless cleaning surface may be to engage with the intermediate transfer member when heated to transfer residue from the intermediate transfer member to the layer of thermoplastic print agent on the endless cleaning surface.

Abstract: A press includes a blanket cylinder, an impression cylinder, and a roller. The impression cylinder rollingly engages the blanket cylinder to form a nip and includes at least one gripper configured to selectively secure an end of a media sheet relative to the impression cylinder. The roller is selectively engageable against the impression cylinder to apply to pressure to the secured media sheet prior to its passage through the nip.

Abstract: According to some examples a substance displacement apparatus may comprise a gas ejection aperture and a deflector arm. The gas ejection aperture may be to direct gas towards a roller having a surface on which a substance is disposed. The deflector arm may be moveable between a first position in which gas is directed away from a target area on the surface of the roller, and a second position in which gas is directed towards the target area on the surface of the roller, thereby to displace at least some of the substance from the surface of the roller within the target area. A method and a print apparatus are also disclosed.
