What Is an Image Scanner?

An image scanner is a device that captures a digital image of a physical photo, document or object. It allows you to upload printed materials into your computer so you can view, edit or store them digitally.

To use an image scanner, place the item you want to scan face down on the scanner glass or automatic document feeder. Select your scan settings like resolution, color mode (RGB or black and white), and file format (JPEG or PDF) using the scanner software on your computer. Then simply click “scan” and your item will be converted into a digital file that appears on your screen.

image scanners come in different sizes and types:

Flatbed scanners

are the most common and versatile. They have a lid that opens to reveal a glass scanning surface. They can scan photos, books, and delicate documents.

Sheet-fed scanners

have an automatic document feeder that pulls single sheets through for scanning. They’re ideal for scanning multiple loose leaf documents or business cards.

Portable scanners

are small, lightweight scanners that can be moved around. They’re convenient but typically lower resolution.

High-speed scanners

use fast-scanning technology to scan hundreds of documents per minute. They’re designed primarily for large-volume scanning in offices and libraries.

With the range of scanners available, there’s a solution for digitizing practically any physical media to back up and organize your files, enable searchability, and improve accessibility of information. The possibilities for using and sharing digital scans are endless!

Types of Image Scanners: Flatbed, Sheetfed, Handheld

So you want to scan your old photos, documents or artwork into digital files, but aren’t sure where to start. The good news is there are a few types of scanners to choose from.  Flatbed Scanners

Image Scanner

These are probably the most common and versatile. They have a flat glass surface that you place your item on, then a light and sensor move underneath to capture the image. Great for scanning photos, documents, books and small 3D objects. The downside is they tend to be bulkier and more expensive.

Sheetfed Scanners

As the name suggests, these feed single sheets through a roller system to scan them. They’re fast, compact and budget-friendly but can only handle single sheets, not bound items. Fine for basic document scanning needs.

Handheld Scanners

These portable wand-style scanners let you scan items on the go. Simply glide the wand over the item to capture the image. Very compact and affordable but typically lower resolution and image quality. Suitable for quick text scans or capturing images to digitize later with a flatbed scanner.

The choice ultimately comes down to your specific needs, how often you scan and your budget. A combo of a flatbed scanner for higher quality scans plus a sheetfed or handheld model for speed can be a great, flexible solution. With the right equipment and a few tips for getting the best scans, you’ll be digitizing in no time!

Key Features to Look for in an Image Scanner

When shopping for an image scanner, look for these key features:

Color Depth

Do you need to scan color photos or black and white documents? Choose between a grayscale, color, or black and white only scanner. For color photos, look for at least 24-bit color or “millions of colors”. This will capture color detail and subtle variations accurately.

Scanning Area

The scanning area refers to the maximum size of originals the scanner can scan. If you only need to scan letter or legal sized documents, a standard 8.5″ x 11.7″ area is fine. For photos, books or artwork, look for a larger scanning area, 11″ x 17″ or larger. Some scanners offer additional attachments to scan even larger originals.

Scan Speed

If you plan to scan high volumes of originals, consider a faster scanner, measured in pages per minute or seconds per scan. Faster scan speeds, like 30 ppm or less than 3 seconds per scan, can save you time, especially for single-sided scanning. For occasional scanning, moderate speeds around 10 to 15 ppm are acceptable.


Most modern scanners connect via USB, but some offer additional connectivity like Wi-Fi or Ethernet for wireless networking. Wi-Fi connectivity provides more flexible placement options and the ability to scan directly to mobile devices. Ethernet ports allow for wired network connectivity if Wi-Fi isn’t available.

Document Feeding

An automatic document feeder (ADF) allows you to scan multipage documents, photos, or business cards in one batch. An ADF that holds at least 50 sheets is good for most needs. For high volume scanning, look for an ADF with a larger capacity, up to 100 sheets or more.

Following these guidelines will help you choose an image scanner with all the right features for your needs. Shop around at local and online retailers to compare different makes and models, then you can get scanning with confidence.

Tips for Getting the Best Scan Quality

Getting high quality scans from your image scanner requires a few tips and tricks. Follow these steps to achieve the best results:

Choose the Right Resolution

For most scanning needs, a resolution between 150 to 300 dpi (dots per inch) should work great. Higher resolutions, like 600 dpi, are only needed for scanning photos or documents where fine details are important. Sticking with a lower resolution will keep your file sizes manageable and prevent wasting time and space.

Preview and Crop

Use the preview feature to view your item on the scanner screen. Check that it’s placed correctly and crop the scan area to exclude any unwanted portions around the edges. Cropping will result in higher quality scans since the scanner is focusing on just your item and not the surrounding area.

Clean the Scanner

Dust, dirt, and debris on your scanner surface or under the scan head can show up in your scans. Gently wipe down the entire scanner surface and scan head with a soft, dry cloth to remove any particles before scanning. For stuck-on messes, you can dampen the cloth slightly with water or a mild glass cleaner.
