Liquid ejection apparatus, winding control method, and computer readable recording medium

A winding control method implemented by a liquid ejection apparatus,

• the liquid ejection apparatus including:
• a conveying unit configured to convey a printing medium in a conveying direction;
• a recording head configured to eject liquid on the printing medium for image formation while moving in a direction perpendicular to the conveying direction;
• and
• a winding unit configured to wind the printing medium,
• the winding control method comprising controlling the winding unit to perform a first rotation in which the winding unit rotates in a winding direction, in response to conveyance of the printing medium in the conveying direction by the conveying unit for image formation, until a looseness amount of the printing medium at the winding unit reaches zero, and to perform a second rotation in which the winding unit rotates in a reverse direction opposite to the winding direction while conveyance of the printing medium in the conveying direction by the conveying unit is stopped for image formation until the looseness amount of the printing medium reaches a predetermined amount.

A non-transitory computer-readable recording medium that contains a program that causes a computer of a liquid ejection apparatus to perform a winding control method,

• the liquid ejection apparatus including:
• a conveying unit configured to convey a printing medium in a conveying direction;
• a recording head configured to eject liquid on the printing medium for image formation while moving in a direction perpendicular to the conveying direction;
• and
• a winding unit configured to wind the printing medium,
• the winding control method comprising controlling the winding unit to perform a first rotation in which the winding unit rotates in a winding direction, in response to conveyance of the printing medium in the conveying direction by the conveying unit for image formation, until a looseness amount of the printing medium at the winding unit reaches zero, and to perform a second rotation in which the winding unit rotates in a reverse direction opposite to the winding direction while conveyance of the printing medium in the conveying direction by the conveying unit is stopped for image formation until the looseness amount of the printing medium reaches a predetermined amount.
