Ink condensate removal in hardcopy apparatus

Vapour removed from the drying chamber (15) of a hardcopy apparatus is condensed at (20) and passed to a reservoir (25) from which it is intermittently pumped into an ink supply cartridge (30). Cartridge (30) supplies ink (31) from a first bag (32) via a first nozzle (34). As the bag (32) contracts, it allows a second bag (37) to expand to receive the condensate from reservoir (25) via a valving system (75) and a second nozzle (36). In addition, a pump (40) supplies air the second bag (37) via piping (41, 42, 43); by switching over the valving system (75), it is the same pump (40) which is used to transfer the condensate from reservoir (25) to the cartridge (30).

Printing system with uniform heating

Cleaning apparatus and method of assembly therefor for cleaning an inkjet print head

Cleaning apparatus and method of assembly therefor for cleaning an inkjet print head (40). The cleaning apparatus comprises a web supply (230) for supplying a cleaning web (240) therefrom and a web receiver (260) for receiving the web. A web drive (270) drives the web from the web supply to the web receiver. The web drive pulls the web from the web supply with a first tension force and also pulls the web onto the web receiver with a second tension force greater than the first tension force, so that the web is wrinkle-free while the web slidably engages an exterior surface of the print head to clean the print head. The web remains wrinkle-free to ensure that the surface of the web will contact the surface of the print head without gaps in contact coverage. This enhances cleaning effectiveness compared to a cleaning web having wrinkles.

Printing apparatus and method

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.

Printhead service station

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.

Servicing printheads

A hardcopy device comprises a printhead which extends across a print media path, and movable service station components which are moved in a direction parallel to the longitudinal axis of the printhead and into a position between the printhead and the print media path, whereby to undertake a servicing operation on the printing member. The printheads are lifted away from the print media path to allow the movement of the service station components. The service station components may move along a track which is angled to one side of the hardcopy device. Different service station components may be provided at opposite sides of the hardcopy device.

System and method for draining ink from ink receiving devices

Absorbent pads are provided at various positions on a substrate of a service station. The substrate may be in the form of a device intended to be implemented during a capping operation of ink ejection elements, e.g., printheads, pens, etc. Ink accumulated in the absorbent pads may be substantially removed and stored in a receptacle to thereby enable to absorbent pads to be capable of absorbing additional amounts of ink. The transfer of ink from the absorbent pads to the receptacle may be facilitated by a transfer member connecting the two components. The absorbent pads may selectively contact and disengage from the transfer member at various moments during, for example, a servicing routine. The receptacle may be a spittoon that may also be implemented to receive spit ink from the ink ejection element.

Druckvorrichtung und steuerverfahren

Printing device and control method

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.
