Scanners are devices used to digitize documents and images. The main types include flatbed, sheet-fed, handheld, and drum scanners. Flatbed scanners are versatile for photos and documents. Sheet-fed scanners are ideal for bulk scanning. Handheld scanners offer portability, while drum scanners provide high-quality scans for professional use.
Scanners are selected based on factors like purpose, size, and features. Consider what you'll scan most often: photos, documents, or both. Think about the required resolution and speed. If you need portability, opt for a compact model. For high-volume tasks, a sheet-fed scanner is efficient.
Scanners' resolution determines image quality and detail level. Measured in dots per inch (DPI), higher DPI means sharper images. For standard document scanning, 300 DPI suffices. For photos or detailed graphics, consider 600 DPI or more to ensure clarity and precision.
Scanners with wireless capability offer flexibility and convenience by allowing you to scan directly to devices without cables. They suit modern setups where space is limited or when multiple users share the device. Wired scanners may offer faster data transfer rates but lack this flexibility.
Scanners should have features that match your requirements like automatic document feeders (ADF) for multi-page scanning, duplex scanning for double-sided pages, and OCR (Optical Character Recognition) for text recognition in scanned documents. Connectivity options like USB or Wi-Fi can also enhance usability.
