ABSTRACT:
An automatic cut-sheet feeder incorporated in a printer includes an upper sheet guide having an ink ribbon replacement recess defining a clearance between the upper sheet guide and a print head of the printer for thereby allowing an ink ribbon cassette to be replaced with ease. When a cut sheet is fed to the front side of a platen, the print head mounted on a carriage is controlled to move to a position corresponding to the ink ribbon replacement recess in the upper sheet guide. The printed cut sheet can smoothly be discharged by the upper sheet guide into a stacker. The ink ribbon cassette on the print head can easily be replaced with a new one.
