Use store fixtures instead of document scanners when the required outcome is safe, accessible physical capacity for merchandise or retail service. Fixtures use shelves, brackets, uprights, cases, counters, hooks, bases, anchors, and clearances to carry loads and organize interaction. Document scanners perform an information-conversion task by measuring paper originals and creating digital page images.
The decision therefore turns on the work artifact and acceptance evidence. A fixture needs compatible components, verified load paths, installation, capacity, access, and recurring condition checks. A scanner needs capture completeness, image quality, page order, indexing, and repository acceptance. Digitizing a fixture drawing cannot commission the installed assembly.
