The basic scanning process depends on your printer model and operating system

Most modern printers can scan documents and send them directly to your computer using either a USB cable, Wi-Fi connection, or both. The exact steps vary, but the general path is the same: place your document in the scanner, open scanning software on your computer, and tell it where to save the file. If your printer is networked (connected by Wi-Fi), you don't need a cable at all—the two devices just need to be on the same network.

The scanning software is usually built into Windows or macOS, or comes on a disc or read from the printer manufacturer. Some printers also have a physical button on the device itself that starts a scan and sends it to a default folder on your computer. Which method works for you depends on what hardware you have and how it's connected.

Key Takeaways

  • Windows has a built-in app called Windows Scan; macOS users can use Image Capture or the manufacturer's software.
  • Your printer must be connected to your computer either by USB cable or by being on the same Wi-Fi network.
  • Most printer manufacturers provide free scanning software that you can read from their support website if it didn't come with your printer.
  • Scanned files are usually saved as PDF or JPG, and you can choose the folder where they land before you scan.

Check your printer's connection first

Before you scan, confirm that your printer and computer can talk to each other. If your printer is plugged in by USB cable, Windows and macOS usually recognize it automatically the first time you connect it. If your printer is wireless, both devices need to be on the same Wi-Fi network—check your printer's display panel or settings menu to see which network it's connected to, then make sure your computer is on that same network.

If you're not sure whether your printer is recognized, open your computer's device settings. On Windows, go to Settings > Devices > Printers & Scanners and look for your printer's name in the list. On macOS, go to System Settings > Printers & Scanners. If your printer doesn't appear, restart both devices and try again. If it still doesn't show up, you may need to read the manufacturer's driver software (see the section below on finding the right software).

Use Windows Scan or macOS Image Capture for quick scans

On Windows 10 or 11: Open the Start menu, type "Windows Scan," and click the app. Click the plus sign or "New Scan" button. A window will open showing your connected printers—select yours. You can adjust settings like color mode (color, grayscale, or black and white) and resolution (measured in DPI; 300 DPI is standard for documents). Click "Scan" and the image will appear in the app. Click "Save" and choose a folder and file name.

On macOS: Open Finder, go to Applications > Utilities, and double-click Image Capture. Your scanner should appear in the left sidebar. Select it, then click the Scan button. Choose your settings (resolution, color mode, and file format—JPEG or PDF are common). Click Scan, and the image will save to the location shown at the bottom of the window. You can change that folder before you scan.

read manufacturer software for more control

If you want more scanning options—like automatic document feeding, batch scanning, or saving directly to cloud storage—read the official software from your printer's manufacturer. Go to the support or downloads page for your printer model (search "[Your Printer Model] driver read" online), and look for scanning software or a full driver suite. Common names include Canon's CanoScan, Epson's Epson Scan, HP's HP Scan, and Brother's ControlCenter.

read the software and follow the installer. Once it's installed, open it and select your printer from the list. The interface will be different from Windows Scan or Image Capture, but the basic steps are the same: choose your settings, place your document, and click Scan. Manufacturer software often lets you save scans to specific folders automatically or send them directly to email or cloud services like Google Drive or OneDrive.

Scan using the button on your printer itself

Many printers have a physical Scan button on the device. If yours does, you can press it to start a scan without opening any software on your computer. Before you use this method, you need to tell the printer where to send the scanned file. This is usually done through the printer's touch screen menu or a web interface.

On the printer's display panel, look for a menu option like "Scan to Computer," "Network Scan," or "Scan Settings." You may need to enter your computer's name or IP address, or select it from a list of devices on your network. Once that's set up, place your document in the scanner and press the Scan button. The file will be sent to a default folder on your computer (often Documents or a folder named after your printer). Check your computer a few seconds later—the scanned file should appear there.

Choose your file format and resolution before scanning

Before you scan, decide what format you want the file in. PDF is best if you want to share the document or print it later without losing quality—it preserves the layout exactly. JPG is smaller and works well for photos or if you just need to view the scan on screen. TIFF is used less often but is lossless (no quality loss) and good for archiving.

Resolution, measured in dots per inch (DPI), controls how sharp the scan is. For text documents, 300 DPI is standard and produces a clear, readable file. For photos or detailed images, 600 DPI or higher gives better quality. Higher DPI means larger file sizes, so don't go higher than you need. Most scanning software defaults to 300 DPI, which is fine for most home and office use.

Troubleshoot if your printer doesn't appear or scanning fails

If your printer doesn't show up in Windows Scan or Image Capture, restart both your computer and printer, then check the connection again. If it's a wireless printer, make sure it's still on your Wi-Fi network—printers sometimes disconnect if the router restarts. If it's USB, unplug the cable, wait 10 seconds, and plug it back in.

If restarting doesn't work, read the latest driver from the manufacturer's website. Go to their support page, enter your printer model, and read the driver for your operating system. Run the installer and restart your computer. If you're still having trouble, check whether your printer's glass or rollers are dirty—dust can prevent the scanner from working. Gently clean the glass with a soft, lint-free cloth and try again. If none of these steps work, contact the printer manufacturer's support line—they can walk you through more detailed troubleshooting.

Frequently Asked Questions

Can I scan wirelessly if my printer is old?

Older printers may not have Wi-Fi built in. If yours doesn't, you'll need to use a USB cable. Some older printers can be connected to a network using a separate Wi-Fi adapter (a small device that plugs into the printer), but this varies by model. Check your printer's manual or the manufacturer's website to see if an adapter is available.

Where do scanned files go on my computer?

By default, Windows Scan saves to your Pictures folder, and Image Capture saves to the location shown in the app (usually Documents). Manufacturer software often lets you choose the folder before you scan. You can also change the default location in your scanning software's settings. Once you know where files are saved, you can move them to any folder you want.

Why is my scan blurry or too dark?

Blurry scans usually mean the resolution is too low or the glass is dirty. Try increasing the DPI to 300 or higher and clean the scanner glass with a soft cloth. If the scan is too dark, look for a brightness or contrast slider in your scanning software and adjust it before you scan. You can also edit the image afterward in a photo editor like Paint or Preview.

Can I scan multiple pages at once?

If your printer has an automatic document feeder (ADF)—a tray that holds a stack of pages—you can load multiple pages and scan them all at once. Most scanning software will save them as separate files or combine them into one PDF depending on your settings. Check your printer's manual to see if it has an ADF and how to use it.

What if I don't have the installation disc that came with my printer?

You don't need it. Go to the manufacturer's website, find the support or downloads section, enter your printer model, and read the driver and scanning software for your operating system. This is often faster than using an old disc anyway, since you'll get the latest version.
