Claim 0:
1. A multi-function printer, comprising:
a printer body, in which a printer module is disposed; and
a scanner body, in which at least one first scanning module, a feeding roller and a sheet detection sensor are disposed, wherein the sheet detection sensor is disposed outside the first scanning module and at an inlet of a vertical sheet passage, and a nip between the first scanning module and the feeding roller is formed in the vertical sheet passage;
wherein when the sheet detection sensor senses, in the vertical sheet passage, presence of a sheet medium not yet reaching the nip, the feeding roller is immediately rotated to generate vibrations and air streams to move and guide the sheet medium to travel a vertical distance along a vertical path, which is substantially parallel to a vertical mounting surface between the printer body and the scanner body, in the vertical sheet passage and then through the nip, and vertical sheet-fed image scanning is immediately performed, by the first scanning module, on the sheet medium to obtain image data representative of the sheet medium, and then the printer module prints out the image data,
wherein the scanner body has: an inclined surface extending downwardly rightward and being adjacent to the inlet of the vertical sheet passage; and a first cavity frame, which is connected to the inclined surface, and extends, in order, substantially horizontally leftward, substantially vertically downward and substantially horizontally rightward to form a cavity, which is formed under the inclined surface, communicates with the vertical sheet passage, is connected with the inlet and accommodates the sheet detection sensor.
