Key Scanner Features and Specifications

Image Sensors (CCD vs. CIS)

When you pick a scanner, knowing about its image sensor helps a lot. The two main types are CCD (Charge-Coupled Device) and CIS (Contact Image Sensor).

CCD scanners usually give you better pictures. They use more lenses to catch light from the document, making images clearer, especially for photos.

In contrast, CIS scanners are smaller and often cheaper. They work with a single line of sensors that move across the page. While they may not be as good as CCDs for quality, they can still do a decent job for documents.

Feature	CCD Scanner	CIS Scanner
Scan Quality	High	Good
Size	Larger	Compact
Cost	More expensive	Usually cheaper

Optical Resolution (DPI)

Optical resolution is super important when picking a scanner. It tells you how many dots per inch (DPI) the scanner can see while scanning. The higher the DPI, the better the detail in your scans.

For most home users or small offices, a scanner with at least 300 DPI is good enough for documents and photos. But if you’re into high-quality scans—like professional photography or detailed artwork—you should look for a high-resolution scanner that offers 600 DPI or even more.

Knowing about optical resolution helps make sure your scans meet your needs without losing quality.

Color Depth (Bit Depth)

Color depth shows how many colors can fit into an image based on bits used per pixel. The higher the bit depth, the smoother gradients and richer colors you get in scanned images.

Most regular scanners have a color depth of 24 bits. This means they can show over 16 million colors—just right for everyday photo scanning tasks. If you’re into graphic design or fine art reproduction where color accuracy matters, try to find scanners with at least 48-bit color depth capabilities.

OCR (Optical Character Recognition)

OCR technology lets scanners turn printed text into editable digital files through software that recognizes letters and words. An OCR scanner comes with software that helps it read characters correctly from scanned documents.

This is great if you often scan contracts or notes because it saves time by not needing to type everything after scanning them into formats like Word or PDF.

Many newer scanning options have advanced OCR features that make text recognition better than older models.

Connectivity Options

Connectivity options are key for how easily you can use your new scanner at home or work.

USB Scanners: These connect directly using USB cables; they’re dependable but limit how far you can move around.
Bluetooth Scanners: These give you wireless connection within short distances; nice if you want less cable mess.
Wireless Scanners: These connect over Wi-Fi networks so you can access them from different devices around your home office without needing cords each time you scan something.

Choosing the right features will help find which type of scanner suits your needs best!
