Use document scanners instead of general office machines when paper capture is a sustained production process with meaningful requirements for throughput, mixed media, duplex completeness, double-feed detection, image profiles, OCR, indexing, quality review, and repository delivery. A multifunction printer can scan pages, but its shared design may prioritize copying and printing over capture control.
The decision is not based on advertised pages per minute alone. It depends on batch variability, missing-page risk, operator handling, required image fidelity, metadata, downstream systems, and support ownership. This explainer identifies when dedicated capture reduces operational and records risk and when an office machine remains the simpler choice.
