In an aspect, an inspection method for detecting the presence or absence of a defect on an object, the object comprising a recess having a physical depth, is disclosed. The device is hand cradleable with an elongate body configured to be held in one hand by an operator during text entry. An individual label with an active portion is produced from the roll-fed label web when the web is cut at the cut zones by a label application machine. In a second embodiment, each BLM is split into more than two segments. Sources of illumination that exhibit such patterns are arranged to physically correspond to indicia of such functions and actions to facilitate knowing selection thereof. Bytes of data in the stream may be shifted to avoid defective locations in the memory such as bad columns.
