Printer system having a cover and reservoir connectable to a tank

A system comprising:

• a housing;
• a cover that is supported by the housing to be movable between a covering position, where an upper end of the housing is covered, and an opened position, where the upper end of the housing is opened;
• a tank that is disposed inside the housing and is configured to store liquid;
• a reservoir that is connectable to the tank and is configured to store liquid;
• and
• a liquid discharging head that is disposed inside the housing and configured to discharge liquid supplied from the tank,
• wherein the reservoir includes a liquid passage hole through which the stored liquid is flowable to an outside of the reservoir,
• the tank includes a passage tube that extends upward from the tank and is connectable to the liquid passage hole of the reservoir,
• the passage tube includes a first flow path having an upper end that is opened to an inside of the tank and having a lower end that is opened to an outside of the tank through the passage tube and a second flow path having an upper end that is opened to the inside of the tank and having a lower end that is opened to the outside of the tank through the passage tube;
• the cover includes:
• a first wall that is positioned above the housing at the covering position;
• and
• a second wall that extends downward from an edge of the first wall and facing a front side in a front-rear direction intersecting a height direction, and
• when the cover is positioned at the covering position and the reservoir is connected to the tank, both of the upper ends of the first flow path and the second flow path of the passage tube are positioned below a lower end of the second wall.
