  • Publication number: 20240131848
    Abstract: A liquid ejecting apparatus includes a liquid ejection head to eject liquid, a recovery unit, a housing, a discharge unit, a casing including the discharge unit and the housing, and a liquid receptacle. The recovery unit maintains liquid ejecting performance of the liquid ejection head. The housing houses a container that accommodates liquid received by the recovery unit. The discharge unit discharges the liquid received by the recovery unit to the container. The liquid receptacle is disposed below the discharge unit in a direction of gravity in the casing and includes a first groove extending in a first direction crossing the direction of gravity and a second groove extending in a second direction crossing the direction of gravity and the first direction.

  • Publication number: 20240109330
    Abstract: A printing apparatus includes a liquid tank unit, a printing head, and a supply tube unit. The liquid tank unit includes first and second liquid tanks that store liquid and are arranged in parallel to each other. The printing head ejects liquid from the first and second tanks while moving in a main scanning direction. The supply tube unit includes a first supply tube connecting the first liquid tank to the printing head and includes a second supply tube coupled in parallel to the first supply tube and connecting the second liquid tank to the printing head. The second supply tube transitions from a connected tube state in which the second and first supply tubes are coupled in parallel to a single tube state by being separated from the first supply tube, passes across the first supply tube, and is connected to a connection port of the second liquid tank.
