  • Patent number: 6112655
    Abstract: A stencil printer includes a rotary printing drum around which the stencil master is wrapped, a main motor which rotates the printing drum, a press roller which is rotatable in parallel to the printing drum in contact with the printing drum, and a pair of opposed conveyor rollers which feed a printing paper between the printing drum and the press roller. A conveyor roller motor is provided separately from the main motor and drives the conveyor rollers. A printing drum rotation detector detects rotation of the printing drum on the basis of the reference position, and a conveyor roller rotation detector detects rotation of at least one of the conveyor rollers.
