Abstract
In this printer, switching between a single-sheet form feed path and a continuous form feed path occurs by rotating a paper guide when feeding the forms. When the printed single-sheet form is to be discharged onto a table, the tail end of the form is detected by a first single-sheet form sensor. Form feed is stopped for a moment, and the paper guide is rotated toward the continuous form feed path. Reverse feed of the form is resumed and continued until the tail end of the form reaches approximate center of the paper guide. The paper guide is then rotated toward the single-sheet form feed path. The tail end of the form is bent toward the table, and the form is discharged onto the table. As a result, single-sheet forms fed from a manual insertion port or from an automatic paper sheet feeder can be conveyed after finishing printing to the position where the forms are inserted in a stabilized manner without causing the forms to jam on the discharge path.
