Claim:
A stencil printing machine comprising: a drum rotated by a main motor, the drum having an outer circumferential wall formed by an ink impermeable member; a stencil clamping part provided on the outer circumferential wall to clamp a leading end of a stencil sheet; an ink supply unit having an ink supply opening positioned in the outer circumferential wall to supply a surface thereof with ink; a press roll arranged close to the drum to press a printing medium on supply against the outer circumferential wall of the drum; an ink recovery unit having an ink recovery opening formed on a downstream side of a maximum printing area in a rotating direction of the drum to collect ink flowing into the ink recovery opening by suction, the maximum printing area being defined on the outer circumferential wall; a press unit for pressing the stencil sheet onto the outer circumferential wall of the drum; and a control unit for controlling respective operations of the main motor, the ink recovery unit and the press unit, wherein, in process of fitting the stencil sheet on the drum while clamping the leading end of the stencil sheet by the stencil clamping part, the control unit allows the press unit to press the stencil sheet onto the outer circumferential wall of the drum and further allows the ink recovery unit to start a suction operation through the ink recovery opening.
