Abstract: A method of operating a device to receive a print medium is disclosed. Rotation of a receiving device to receive a print medium is detected, whereby the rotation is caused by an external force. An assisting force is applied to further rotate the receiving device in response to the detected rotation.

Abstract: According to an example, a method to wind media in an output roller downstream a media advance engine comprises advancing a medium for a determined medium length, collecting a first portion of the determined medium length at a first speed by rotating the output roller in a winding direction, and collecting a second portion of the determined medium length by rotating the output roller in a winding direction at a second speed, wherein the first speed is greater than the second speed.

Abstract: According to an example, a media roll support may comprise a sliding element movable along a guide, a hub to receive the media roll and a coupling plate. The hub may comprise an elastic element biased towards a first side of the media roll. The coupling plate may be attached to the hub and to the sliding element. Upon holding the media roll, a deformation of the elastic element may tilt the sliding element. The tilting of the sliding element may lock the sliding element movement, thereby preventing its movement.

Abstract: In one example, an elevator for a roll of print media includes rotatable shafts oriented parallel to one another and translatable supports to support a roll of print media. Each support is operatively connected to the shafts such that rotating the shafts in a first direction raises the supports and rotating the shafts in a second direction opposite the first direction lowers the supports.

Abstract: In one example in accordance with the present disclosure a device to detect media being wound around a wheel is described. The device includes a reel that collects the media and a movable arm pivotally coupled to the reel to provide tension to the media being wound around the reel. The device also includes a controller that detects media is being wound around the reel by 1) determining an angular position of the movable arm and 2) calculating, based on the angular position of the movable arm, when an output of a motor that rotates the reel is non-zero.

Abstract: A printing medium holder system is described which has first and second printing medium holders, a connection mechanism to connect the holder system to a printer and a pivot mechanism. The pivot mechanism is connected to each of the first printing medium holder, the second printing medium holder and the connection mechanism. The pivot mechanism is pivotable so that each of the first printing mechanism holder and the second printing mechanism holder move relative to the connection mechanism between a first configuration of the holder system and a second configuration of the holder system. A printing system and a printing device are also described.

Abstract: A fluid ejection device includes a fluid-ejection mechanism, a scanning carriage, and a service station. The fluid-ejection mechanism is capable of ejecting fluid onto media. The scanning carriage is that on which the fluid-ejection mechanism moves while ejecting fluid onto the media. The service station is that to which the fluid-ejection mechanism is movable by the scanning carriage, and that at which fluid aerosol from the fluid-ejection mechanism is extracted by a vacuum via an airflow path from the fluid-ejection mechanism temporarily fluidically coupled to the vacuum during servicing of the fluid-ejection mechanism.

Abstract: An aerosol extraction system for a fluid-ejection device is disclosed that includes a print zone, a servicing zone, a vacuum, and a switching mechanism. The print zone is that in which a print head of the fluid-ejection device ejects fluid onto media to form images thereon. The servicing zone is that in which the print head is serviced. The vacuum is fluidically connectable to both the print zone and the servicing zone. The switching mechanism is to fluidically connect and disconnect at least one of the print zone and the servicing zone to the vacuum.

Abstract: 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.

Abstract: 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.

Abstract: A media holddown device a plastics vacuum guide attached to a sheet metal vacuum beam, the guide includes vacuum chambers in communication with the beam through openings to control the negative pressures applied to media of varying widths by a fan. Dividing walls are provided between the chambers to maintain the value of the negative pressure larger than a predetermined value, especially for media with conventional widths. An intermediate wall divides the guide into front and rear chambers to increase the control of media leading edges. The number, size and pattern of arrangement of openings are selected to produce desired air flow characteristics.
