A method of detecting an obstacle that disturbs a printing operation to be performed on a printing surface of a printing portion of a workpiece by a printing head of an ink-jet printer such that the printing head and a planar platen on which the printing portion of the workpiece is set are moved relative to each other between a first position and a second position, with a predetermined spacing maintained between the printing surface of the workpiece and the printing head in a direction perpendicular to the printing surface, wherein the obstacle existing on a plane of printing by the printing head is detected by a sensing device, by scanning the predetermined spacing in a direction intersecting a direction of a relative movement of the printing head and the platen, while the printing head and the platen are moved relative to each other between the first and second printing positions. Also disclosed are an ink-jet printing method and printer wherein the obstacle is detectable.
A method of detecting an obstacle that disturbs a printing operation to be performed on a printing surface of a printing portion of a workpiece by a printing head of an ink-jet printer such that said printing head and a planar platen on which said printing portion of the workpiece is set are moved relative to each other between a first position and a second position, with a predetermined spacing maintained between said printing surface of said workpiece and said printing head in a direction perpendicular to said printing surface, said method comprising (a) moving said printing head and said platen relative to each other between said first and second positions;
A method of printing an image on a printing surface of a printing portion of a workpiece by an ink-jet printer including a printing head operable to perform a printing operation on said printing surface, and a platen device which includes a planar platen, said method comprising the steps of:
An ink-jet printer including a printing head operable to perform a printing operation on a printing surface of a printing portion of a workpiece, and a platen device including a planar platen on which said printing portion of the workpiece is set, said printing head and said platen device being movable relative to each between a first position and a second position, with a predetermined spacing maintained between said printing surface of said workpiece and said printing head in a direction perpendicular to said printing surface, said ink-jet printer comprising:
