A printer comprises a first sheet feed mechanism comprising a first transportation unit and a first sheet container, and a second sheet feed mechanism comprising a second transportation unit and a second sheet container. A sheet fed from the second sheet container is transported by the second transportation unit to the first transportation unit. The insertion of a sheet fed from the second sheet container into the first transportation unit is detected by a sheet detector. The feed speed of the second transportation unit is adjusted to a feed speed higher than that of the first transportation unit before the sheet detector detects the leading edge of a sheet fed from the second sheet container. The feed speed of the second transportation unit is adjusted to a feed speed not higher than that of the first transportation unit upon the detection of the leading edge of the sheet fed from the second sheet container by the sheet detector. <IMAGE> |
