A method of tensioning a print medium on a drum comprising: supporting the medium on the drum; rotating the drum; and applying a gaseous flow to the medium on the drum, the gaseous flow having a major component that is tangential to the drum and in a direction that is opposite to the linear direction of the surface of the drum.

Apparatus and method of tensioning print media

A small footprint drum inkjet printer having a print head consisting of a number of print head arrays; a substrate carrier preferably in the form of a drum with vacuum orifices therein, a substrate loading cassette capable of movement, relative to the drum, in at least one direction; a substrate unloading cassette capable of movement, relative to the drum, in at least one direction, and a curing radiation source having a reflector which extends along the drum surface.

Drum printer with automatic loading and unloading

A carrier for an array comprising a plurality of print heads, comprises an elongate bar having an ink conduit extending through the bar in a longitudinal direction. The carrier also comprises a print head receiving area adapted to receive or mount the plurality of print heads, and a heat transfer fluid conduit extending through the bar in a longitudinal direction. The carrier is arranged so that each print head received or mounted in the print head receiving area is in fluid communication with the ink conduit, wherein the heat transfer fluid conduit is disposed adjacent both the ink conduit and the print head receiving area. The carrier may comprise two ink conduits and two heat transfer fluid conduits. Heat transfer fluid may in use be conducted along the first and second heat transfer conduits in opposite directions.

Inkjet printing

The present invention is concerned with a drum printer in which the loading and unloading of printing medium onto and off a drum of the printer is performed without interrupting or decelerating the drum rotation and the printing process.
