Cap device, capping method, and liquid jet system

A capping method of capping a liquid jet head, the capping method comprising:

• via a cap device including
• a seal member that is brought into contact with a seal position defined on a side surface of the liquid jet head, and
• a seal member support mechanism that supports the seal member to be movable with respect to the side surface, the seal member support mechanism including a swing member that supports the seal member to be swingable about a swing shaft along a first direction in which the seal member extends,
• in which a head abutting position where a lower surface of the liquid jet head, which is a surface different from a nozzle surface of the liquid jet head and faces a direction parallel to a second direction in which the nozzle surface faces, abuts is defined in the swing member,
• moving, in a case in which the seal member is moved in the second direction and a fourth direction in which a normal line of the side surface faces as the liquid jet head of which the lower surface abuts on the head abutting position moves in a third direction opposite to the second direction, the seal member in the fourth direction by a distance, which is at least twice a moving distance in the second direction, to separate the seal member from the seal position.

A liquid jet system comprising:

• a liquid jet head;
• and
• a cap device that caps the liquid jet head,
• wherein the cap device includes
• a seal member that is brought into contact with a seal position defined on a side surface of the liquid jet head, and
• a seal member support mechanism that supports the seal member to be movable with respect to the side surface, the seal member support mechanism including a swing member that supports the seal member to be swingable about a swing shaft along a first direction in which the seal member extends, and
• in the swing member,
• a head abutting position where a lower surface of the liquid jet head, which is a surface different from a nozzle surface of the liquid jet head and faces a direction parallel to a second direction in which the nozzle surface faces, abuts is defined, and
• in a case in which the seal member is moved in the second direction and a fourth direction in which a normal line of the side surface faces, as the liquid jet head of which the lower surface abuts on the head abutting position moves in a third direction opposite to the second direction, the seal member is moved in the fourth direction by a distance, which is at least twice a moving distance in the second direction, and separated from the seal position.
