In some examples, a first heating stage heats a print medium to a first temperature in a printing region when printing latex ink on the print medium, and a curing heating stage heats, in a curing zone, the print medium to a curing temperature greater than the first temperature to cure the latex ink on the print medium. A cooling stage located between the first and curing heating stages cools the print medium by directing a first part of airflow from the cooling stage to a printing zone, the cooling performed after the print medium has been heated by the first heating stage and prior to heating of the print medium by the curing heating stage. A second part of the airflow is directed from the cooling stage to the curing zone.

Printing onto a print medium

Arrangement or method for collecting and heating print substance that passes through porous media in a printer.

Collect print substance

A controller controls a first heating stage to heat a printing medium to a first temperature in a printing region when printing latex ink on the printing medium, and controls a second heating stage to heat the printing medium to a second temperature greater than the first temperature in a curing region to cure the latex ink on the medium. The controller controls a cooling stage located between the first and second heating stages to cool the printing medium after the printing medium has been heated by the first heating stage and prior to heating of the printing medium by the second heating stage.

Printing device and control method

A printing device and method for printing a latex ink on a printing medium is disclosed. The printing device comprises a heating stage for heating the medium at least during printing the latex ink on said medium, a further heating stage for curing the latex ink on the medium and a controller arrangement for individually controlling the heating stage and the further heating stage, whereby the controller arrangement is arranged to reduce the heat output of the heating stage during a non-printing mode of the printing device and to reduce the heat output of the further heating stage during a non-curing mode of the printing device.

A cutter assembly for cutting printed media in a printer comprises a housing arranged for displacement across a media path, in a cutting direction at right angles to a media advance direction in the printer, a first rotary cutting blade carried on said housing such as to be positioned generally on the printed side of the media, and a second rotary cutting blade carried on said housing such as to be positioned generally on the side of the media opposite the printed side, the cutting blades being engageable with each other such as to cut the media between them, and the first rotary cutting blade being arranged upstream of the second rotary cutting blade in the media advance direction.

The method comprises the steps of feeding media from a media roll, arranged about an axis, through an input driving device and an output driving device of the media advance mechanism, wherein the output driving device engages the media with lower friction than said input driving device; releasing said input driving device such that it does not engage the media; and causing the media to move in the media advance mechanism such that the media is pulled taut between the roll and the output driving device and later the media slips with respect to said output driving device, whereby the media is aligned at right angles to the roll axis by effect of the friction between the media and the output driving device.

Method for reducing media skew in a media advance mechanism

Disclosed is a handling device which comprises a lid, which may be arranged to cover at least partially a surface of a replaceable consumable of a printhead service station, engagement members for engaging the lid to the consumable, and a hand grip. The consumable may be replaced by engaging the handling device with the consumable while the latter is still in the service station, and removing the consumable from the service station with the handling device. The risk of getting ink on the user's hands when replacing a consumable is reduced.

A hardcopy device such as an ink-jet printer comprises a printhead, a spittoon for receiving waste ink from the printheads, and a heater for quickly drying the ink waste products in the spittoon. A drum platen having a print media supporting area also has an elongate spittoon region extending across its circumferential surface, the contents of the spittoon region being arranged to be removed intermittently by an elongate scraper which, in one position of the drum, can be moved radially towards the drum to contact the spittoon region.

Removing ink waste

The printheads of an inkjet printer have a service station movable in a direction transversely of a printhead scanning direction and comprising servicing modules for undertaking different functions, one of the modules being detachable from the rest. The detachable connection comprises a rotating hook and a fixed hook which automatically interengage and disengage.

In one implementation, an aerosol collector for an inkjet printer includes a partial enclosure defining a central cavity. An air passage is defined within a wall forming the partial enclosure to allow air movement into an opening defined on an inside surface of the partial enclosure and out of an exhaust outlet. A fan is configured to remove a mixture of air and aerosol from the central cavity, through the air passage and through the exhaust outlet.

Aerosol collector

A inkjet printing device comprising a drum platen, the platen having a recess in its circumferential surface. The recess is adapted to accept an inkjet servicing device. The inkjet servicing device, for example a spittoon, may be permanently or semi-permanently located in the recess. Alternatively, The inkjet servicing device, for example a printhead wiper element, may from time to time pass into or through the recess.

Printing apparatus and method

Vapour removed from the drying chamber of a hardcopy apparatus is condensed and passed to a reservoir from which it is intermittently pumped into an ink supply cartridge. Cartridge supplies ink from a first bag via a first nozzle. As the first bag contracts, it allows a second bag to expand to receive the condensate from reservoir via a valving system and a second nozzle. In addition, a pump supplies air the second bag via piping; by switching over the valving system, it is the same pump which is used to transfer the condensate from reservoir to the cartridge.

Ink condensate removal in hardcopy apparatus

An air pressurization system is incorporated as part of a replaceable auxiliary ink supply for an inkjet printer. The auxiliary ink-supply cartridge includes a pressurized container having air, ink and electrical-signal connections. The air pressure applied to the auxiliary ink supply is monitored to maintain it in a predetermined range in accordance with a start-up sequence, and operational sequence, a waiting time, and a close-down sequence.
