  • Patent number: 10933446
    Abstract: An article carrier is disclosed. The article carrier comprises a mounting portion adapted for connection to a conveyor such that when the article carrier is connected to the conveyor the conveyor is positioned on a conveyor axis of the article carrier. The article carrier has first and second carrier portions connected to the mounting portion which are configured to allow weighing of one or more articles carried, in use, by the carrier portions. The first carrier portion comprises a first bearing surface and a second bearing surface, and the second carrier portion comprises a third bearing surface and a spaced apart fourth bearing surface. A distance between the conveyor axis and any point on one of the bearing surfaces, measured orthogonally to the conveyor axis, is different to a distance between the conveyor axis and any point on any of the other bearing surfaces, measured orthogonally to the conveyor axis.

  • Publication number: 20200391522
    Abstract: A media sensing device may include an electromagnetic radiation source, a light guide located on an opposite side of a media feed path respective to the electromagnetic radiation source, and a photodetector to detect electromagnetic radiation from the electromagnetic radiation source and directed by the light guide. The photodetector detects the presence of media upstream from a heated pressure roller (HPR) in response to the media obstructing the detection of electromagnetic radiation from the electromagnetic radiation source.

  • Publication number: 20200371471
    Abstract: An example device includes a conveyor to convey a printed medium along a path from a print engine towards a printed media output. The device further includes a housing to hold the conveyor. The housing defines an air intake, an exhaust port, and a conveyor volume to contain the conveyor. The air intake provides air to the conveyor volume to dry the printed medium. The device further includes a tortuous exhaust passage extending from the conveyor volume to the exhaust port to exhaust air from the conveyor volume.

  • Patent number: 10730709
    Abstract: In an example implementation, an example printer system includes a lift, an indicator, a trigger, and a reset mechanism. In an example implementation, a lift is orientable by an amount of media when adjacent to the lift and a trigger has a first portion engageable with the lift at a first orientation of the lift. In an example implementation, the trigger causes the indicator to move towards a first location relative to an aperture defined by an exterior surface in response to engagement with the lift. In an example, the reset mechanism has a first portion engageable with the lift at a second orientation of the lift and the reset mechanism causes movement of the indicator away from the first location in response to engagement with the lift.
