摘要： Two rollers (44,55) with lobes for feeding a sheet are disposed below the plane feed surface (22). The two rollers are rotatable on axes perpendicular to one another and move the sheet or the document to be printed in a direction perpendicular and parallel, respectively, to the printing direction (20) of the head (14) to align the sheet against inverted V elements (80) movable parallel to the printing direction, and against lateral guide (158) perpendicular to the printing direction. Suitable optical sensors (155,156) detect possible misalignment of the sheet and cause further rotation of the rollers to complete the alignment of the sheet against the guides. A testing device (108-120) detects the thickness of the document for positioning the head at a prefixed distance from the printing surface of the document itself.

摘要： Two rollers (44,55) with lobes for feeding a sheet are disposed below the plane feed surface (22). The two rollers are rotatable on axes perpendicular to one another and move the sheet or the document to be printed in a direction perpendicular and parallel, respectively, to the printing direction (20) of the head (14) to align the sheet against inverted V elements (80) movable parallel to the printing direction, and against lateral guide (158) perpendicular to the printing direction. Suitable optical sensors (155,156) detect possible misalignment of the sheet and cause further rotation of the rollers to complete the alignment of the sheet against the guides. A testing device (108-120) detects the thickness of the document for positioning the head at a prefixed distance from the printing surface of the document itself.
