Document Scanners

Pick a scanner based on volume (sheets per day), feed type (automatic document feeder for multi-page jobs vs. flatbed for books/photos), required resolution (300 dpi for text, 600 dpi+ for detailed images), connection type (USB, Ethernet, or Wi‑Fi), and software compatibility with your OS and workflow (OCR and searchable PDF support)

Sheet-fed scanners use an automatic document feeder to quickly scan stacks of loose pages, ideal for high-volume text; flatbed scanners have a glass platen for scanning bound materials, fragile documents, or thick items like passports and books. Some models combine both capabilities

OCR (optical character recognition) converts scanned images into editable/searchable text; look for high accuracy, support for multiple languages, export to common formats (PDF, Word, text), and batch/OCR-for-multiple-files capability to streamline document workflows

For small offices, 20–40 pages per minute (ppm) is usually adequate; medium offices often need 40–80 ppm or more. Check the daily duty cycle or recommended daily volume to ensure reliability under your expected workload

Resolution (dpi) affects detail—300 dpi is typically sufficient for text, 600 dpi+ for high-quality images; color depth (bits per channel) affects color accuracy and gradation—24-bit color is common for standard color documents, while 48-bit offers higher fidelity for color-critical tasks

Look for support for searchable PDF, standard image formats (TIFF, JPEG, PNG), and editable formats (Word/RTF or plain text via OCR). Batch output, PDF/A for archiving, and configurable compression options are also useful

Regularly clean the glass/platen and feed rollers per manufacturer instructions, replace consumable rollers or pads when recommended, keep software/firmware updated, and avoid overloading the feeder to prevent jams and mechanical wear
