A method of depositing viscous material on a substrate (includes positioning the substrate in a print position, performing a print operation on the substrate with a print head and a stencil to deposit viscous material on the substrate, and inspecting the substrate with a vision system to detect a defect with the deposit of viscous material on the substrate. The method further includes, in the event of a defect, re-working the substrate by depositing viscous material on the substrate with a dispenser attached to a cleaning assembly for cleaning the bottom surface of the stencil, a shuttle for moving the stencil, or an independent gantry to correct the defect. |
