Abstract: Embodiments of the present disclosure provide a headgear assembly that includes a headband and at least one tube securement member coupled to the headband. The tube securement member includes channel having a first end and a second end. The channel is curved between the first and second ends and defines a receiving region configured to secure a portion of a tube connected to a nasal cannula. The channel faces away from skin of the subject when the headgear assembly is in use.

Abstract: A pick attempt of a media sheet from a media tray is initiated by rotating a pick roller a number of rotations that is set to greater than one in response to the sheet having been designated as a special media sheet type and that is set to one in response to the sheet not having been so designated. In response to a pick sensor detecting the sheet after the pick attempt has been attempted, a turn roller is rotated to advance the sheet to a print engine, and while the turn roller is rotating, the pick roller is rotated to assist advancement of the media sheet. A controller manages per-sheet and per-tray pick attempt counters while the sheet is individually attempted to be picked and advanced, using the counters to determine whether to initiate another pick attempt of the sheet when a current pick attempt has failed.

Abstract: An example system includes a primary device and at least one auxiliary device connected in series with the primary device. The auxiliary device has an identifier indicative of a position of the auxiliary device in the series. The identifier is based on a resistance value associated with the auxiliary device, the resistance value being based at least in part on an upstream device in the series.

Abstract: Embodiments of the invention include a media tray for a media advance mechanism. The media tray includes an access door attached to the media tray via a hinge oriented in a vertical direction and a cleanout disposed on an interior surface of the access door. The access door pivots open around the hinge. The cleanout is mounted such that the cleanout can move translationally along the access door.

Abstract: A printer accessory including a housing and a connector, the connector having a frame defining an opening in the housing, and including a contact housing and a door slideably disposed within the opening. Biasing elements bias the contact housing and door to extend from the opening, wherein the door is configured to be depressed into the housing through the opening to expose electrical contacts on the contact housing.
