A stencil printing method and apparatus for printing paste material in a given pattern on a substrate from a paste dispenser through a stencil to define the stencil pattern on a substrate. The apparatus is provided with a cleaning module that can be moved against the printing face of the stencil and moved, along a given path beneath the stencil, for cleaning the printing face of the stencil. The cleaning module includes a blade assembly mounted there on transverse to the path of movement of the cleaning module. The print apparatus further including selectively operable means for actuating the blade assembly during a select cleaning cycle to engage the leading end of its blade with the underside of the stencil as the cleaning module is passed beneath said stencil whereby the leading edge of the blade scrapes debris from the underside of said stencil. The stencil printing and cleaning method of the invention uses the steps of: dispensing a paste material through a stencil onto a substrate surface to define a given pattern thereon; and passing a cleaning module, provided with a scraping blade that can be extended above the module to contact the lower surface of the stencil to clean the underside thereof when the leading edge of the blade is in contact with the underside of the stencil.
