A blade engagement apparatus for metering release agent onto an image forming device associated moving surface, such as a Solid Ink Jet drum. The blade engagement apparatus includes a blade positioning mechanism having a blade holder rotated about a fixed pivot point disposed a distance LD from the moving surface. A plurality of metering blades extending from the blade holder each include a blade tip disposed a distance LB from the pivot point such that LB is greater than LD. A replacement blade is brought into a working position in deflected engagement with the moving surface for metering a release agent onto the surface while the used blade is moved into a non-operational suspended position. Various blade replacement strategies are used to initiate a blade replacement operation.
